Frequently Asked Questions — Demountable Partition Walls

What is a demountable partition wall?

A demountable partition wall is a modular, non-masonry, dry-construction interior wall system built for relocation possibility. Unlike fixed walls — masonry or gypsum drywall — which require demolition to alter, a demountable partition is engineered so that panels can be removed, services can be accessed, and the entire wall can be dismantled and reassembled in a new position without damaging the base building. The frame, the panels and the services within the cavity are all recoverable. Demountable partitions are also searched for as modular partition walls, relocatable partitions, system walls, movable office partitions, solid partitions, panel partitions and office modular partition systems.

A movable or operable partition slides or folds on ceiling and floor tracks to open or close a space on demand — hotel ballrooms, conference halls, banquet spaces. It is engineered for frequent, daily operation by building users. A demountable partition, once erected, stays in place like a conventional wall: solid, stable, acoustically sealed. Its distinction from fixed construction is that it can be systematically dismantled during a planned reconfiguration and reassembled elsewhere. The modularity is structural, not operational. If you need to open and close a space routinely during occupied hours, specify a movable wall. If you need a permanent-feeling, acoustically rated wall that reconfigures at the pace of organisational change, specify a demountable partition.

The difference is reversibility. A gypsum drywall partition is built wet-and-fixed on site — studs, boards, taping, jointing, sanding, priming, painting — and altering it means demolition, debris, dust and repainting of adjacent surfaces. A demountable partition is a dry, engineered system assembled from pre-finished components; panels come off without tools, services are reached without cutting, and the wall relocates without demolition. Drywall costs less at first installation. Demountable costs less across a building’s reconfiguration cycles, because the second, third and fourth changes are near-free where drywall charges full price every time.

Choose by acoustic requirement, panel material and installation speed.

WP03P is the flagship: a 44×50mm post and 60×9mm rail frame, a 26mm continuous service cavity, panels from 6mm to 25mm on a 25×10mm hook section, and continuous EPDM gaskets on all four perimeter edges of every panel. That gasket line is what delivers its certified STC 51 rating. Specify WP03P wherever acoustic privacy is a stated requirement — boardrooms, consulting rooms, executive offices, HR and legal.

 

WP01P shares the post-and-rail architecture but is derived from the WP01 wall paneling system doubled into partition configuration. It uses a 50×44mm post and a 12×53mm rail with integral hook, a 25mm cavity, panels from 6mm to 18mm on lock clips, and no EPDM gasket line. Specify WP01P for general office partitioning, and particularly where WP01 wall paneling is used elsewhere in the same interior and you want the partitions to read in exactly the same visual language.

 

WP02P is a snap-fit panel-fixing system applied to a separately built frame rather than an engineered frame of its own. It is the fastest to install in the range and accepts the widest panel palette, including gypsum, mineral tile, GRG and PVC. Specify WP02P for speed, for cladding existing walls, for moderate acoustic requirements, and for temporary or semi-permanent configurations.

STC and NRC measure two distinct acoustic properties and should not be conflated. STC — Sound Transmission Class — quantifies how effectively a partition blocks airborne sound passing through it from one room to the next; it is a property of the whole wall assembly. NRC — Noise Reduction Coefficient — quantifies how much sound a surface absorbs rather than reflects within a room, controlling echo and reverberation; it is a property of the exposed panel material. A wall can have a high STC and a low NRC simultaneously: a dense, sealed, hard-faced partition blocks sound extremely well between rooms while reflecting sound back into each. If your requirement is speech privacy between spaces, specify STC. If it is echo and reverberation control inside a space, specify NRC through panel selection. In all three IQUBX systems, NRC is determined by the panel material specified, not by the framing — it is an architect’s choice at panel stage rather than a fixed system property.

The STC scale is logarithmic — a 10-point increment corresponds to roughly a halving of perceived loudness — so small numeric differences matter more than they appear. STC 30–40 provides good general speech privacy, adequate for open-plan enclosures and standard cabins. STC 50 and above means loud speech is inaudible through the wall, which is the threshold normally specified for boardrooms, HR and legal offices, medical consulting rooms, and any space where confidentiality is a stated requirement. Below STC 35, normal conversation remains intelligible through the partition.

Acoustic separation is only as good as its weakest path, and the most common flanking path is the plenum void above a false ceiling. A partition that stops at ceiling level leaves an open acoustic bridge between adjacent rooms regardless of the wall’s rated performance. To preserve a rated partition’s performance, the vertical framing must run full height to the structural soffit, the plenum section must be insulated and sealed, and the head junction must be closed with a continuous acoustic seal. A partition rated STC 51 in the laboratory will perform far below that figure in the field if the plenum is left open.

No. IQUBX partition systems do not currently carry a tested fire resistance rating, and we state that plainly rather than let a non-combustibility claim be mistaken for one. The distinction matters and is widely blurred in this category, so it is worth setting out precisely.

Reaction to fire describes how a material behaves when flame first reaches it — whether it ignites, spreads flame, produces smoke or drips burning material. The 6063 T6 aluminium used in IQUBX framing is non-combustible: it does not ignite, does not sustain combustion, does not contribute to flame spread and produces no smoke or flaming droplets. Solid aluminium profiles without organic coating classify at the highest reaction-to-fire level, Euroclass A1 under EN 13501-1.

Fire resistance is an entirely different measurement. It is a time — 30, 60 or 120 minutes — over which a complete assembly is tested to hold back a fully developed fire while maintaining integrity (E), insulation (I) and, where applicable, load-bearing capacity (R). It is determined by testing the whole wall, not by classifying its materials, under EN 1364-1 or BS 476 Part 22 internationally, or IS 3809 in India as referenced by NBC 2016 Part 4.

A material can be Euroclass A1 and still provide no fire resistance whatsoever. Aluminium melts at approximately 660°C, and a fully developed compartment fire exceeds 1,000°C. In that condition an aluminium frame will soften and lose structural integrity, regardless of the fact that it never burned. Any manufacturer implying that non-combustibility amounts to a fire rating is trading on the ambiguity between the two terms.

What this means for specification. Where the building code requires a rated assembly — fire compartment walls, fire separating walls, enclosures to escape corridors, staircases, lift lobbies and service shafts, and the locations tabulated in NBC 2016 Part 4 — a tested and certified fire-rated system must be used, and IQUBX systems should not be specified. Where the partition is a non-rated internal division, which covers the large majority of commercial office, co-working, institutional and residential partitioning, IQUBX systems are appropriate, and fire load can be materially reduced through the specification choices set out below.

IQUBX intends to pursue formal fire resistance testing. Until that testing is complete and certified, we will not claim a rating.

Four specification choices reduce fire load and flame spread within the assembly. We recommend all four wherever fire performance is a concern, even when a rated assembly is not mandated.

Specify mineral wool, not polyester, as cavity infill. This is the single most consequential choice and it is frequently made carelessly. Rockwool and mineral wool are non-combustible with melting points above 1,000°C. Polyester-based acoustic infill — commonly sold as polywool — is a combustible plastic. Both deliver comparable acoustic performance, so where fire load matters there is no reason to accept the combustible option.

Specify non-combustible or fire-retardant panel faces. Calcium silicate board, fire-rated gypsum, mineral board and glass are non-combustible or near-non-combustible. Where a timber-based panel is wanted for appearance, fire-retardant grade plywood and FR-treated veneer substrates are commercially available in India and internationally, as are intumescent coatings applied to the finished face. All three IQUBX systems accept these materials within their thickness ranges — the panel is a specification variable, not a fixed part of the system.

Firestop the service cavity at compartment junctions. The continuous vertical cavity that makes the system serviceable is also a continuous void, and any continuous void can carry hot gases. Where a partition run crosses a compartment line, or runs floor to soffit adjacent to a rated element, the cavity should be closed with a proprietary cavity barrier or intumescent firestop at that junction. This is standard practice for any cavity construction and should be shown on the partition layout drawing rather than left to the site.

Seal head and perimeter junctions with intumescent seals. Intumescent strips at head, base and abutment expand under heat to close the gap, restricting the passage of smoke and hot gas at the joints.

Taken together these measures reduce fire load and slow smoke movement. They do not confer a fire rating, and we do not present them as a substitute for one.

An installed IQUBX WP03P partition starts at around ₹500 per square foot in India (about USD 5.20), excluding taxes and excluding shipping outside India. That is a floor rather than an average — it is the rate for the minimum standard configuration, which is also the most commonly specified one: 12mm prelaminated particle board panels on both faces, rockwool or polywool cavity infill, posts at 600mm centres and rails at 750–900mm spacing. The figure is all-inclusive at that specification: framing, panels, insulation, labour, installation and normal contractor margin.

Specification decisions move the rate upward from there, and some move it substantially. Natural veneer, perforated acoustic panels, cork on HDF and lacquered back-painted glass on ply backing all sit well above prelaminated particle board on the panel line, and the panel line is the largest single variable in the estimate.

Published ranges for this category vary wildly — Indian listings from ₹200 to ₹350 per sq ft, international sources from USD 15 to 43 — because they rarely state what is inside the number. Demountable partition cost is composed of elements that move independently:

A note on the panel line, because it is widely misunderstood. IQUBX does not manufacture or sell the panels. They are specified by the architect and sourced locally, and the figures above are market rates for finished, installation-ready panels rather than an IQUBX price. The build-up for the most common choice illustrates why the floor sits where it does: prelaminated particle board costs roughly ₹40–50 per sq ft as raw sheet depending on brand, then has to be cut to the panel sizes the grid calls for, then edge-banded on all four sides. Finished and ready to install, that lands at around ₹75 per sq ft — the bottom of the range. Perforated acoustic panels, ply with natural veneer, cork on HDF and similar specifications sit substantially higher, and ₹200 per sq ft is a nominal figure for a great many of them rather than a ceiling.

Panel selection is therefore the largest single swing in the whole estimate, and it is a decision made by the design team rather than by the system.

Higher at first installation, lower across the fit-out’s life. A drywall partition in the Indian market typically runs well below the ₹500 per sq ft installed rate for a base-specification demountable system, because it carries no engineered aluminium frame and no pre-finished panel.

The economics reverse at the first reconfiguration. Altering drywall means demolition, debris removal, new studs, new board, taping, sanding, priming, painting, and the disruption cost of doing all of that in an occupied floorplate — full price, every time, plus the carbon and the waste. Altering a demountable partition means lifting panels off and reassembling them, with frame and panels both recovered. Organisations restructuring floorplates on five-to-seven-year cycles generally recover the premium at the first change. Co-working operators, who reconfigure far more often and typically over-build partitions up front to avoid the cost of later change, recover it faster.

The comparison also omits two things that belong in a proper appraisal: demountable partitions are commonly treated as Plant and Machinery rather than building capital expenditure in many jurisdictions, which changes the depreciation position, and the partition retains recoverable asset value at the end of a lease where a drywall partition does not.

In many tax jurisdictions, demountable and relocatable partition walls are classified as Plant and Machinery rather than building capital expenditure, which permits a materially faster depreciation schedule. The classification rests on the partition being genuinely relocatable and not forming part of the building’s permanent fabric — which is precisely what distinguishes a demountable system from a drywall partition. Treatment varies by jurisdiction and by the specifics of the installation, so confirm the position with your tax advisor before relying on it in a business case.

Yes, where the load path is anticipated at design stage. The frame is engineered to carry sensible equipment and service loads, but a wall-mounted television, shelving run, cabinetry or split air-conditioning unit should be identified before installation so that additional posts or channels are positioned to receive it. Fixing heavy items into panel skins alone, without a framing member behind, is not sound practice in any partition system, demountable or conventional.

Demountability is engineered for authorised reconfiguration, not casual disassembly. Full-height posts run continuously from floor to structural framework, and panels are retained on concealed hook or clip sections that require deliberate tool access to release. Systems can additionally be specified to be lockable from one side only, so that panels can be removed from the secure face but not from a public corridor or shared circulation area.

Yes, and this is one of the principal reasons they are specified. Installation is entirely dry — no wet trade, no curing time, no site cutting of masonry, no painting. Frames arrive knocked down and panels arrive pre-finished, so the noise, dust and debris of conventional partition construction are largely absent. Work can be sequenced in phases around occupied zones and, where required, outside business hours, with the floorplate returned to use the same day.

Maintenance is limited to the panel surface, and the routine depends on the panel material specified rather than the system. HPL faces tolerate hospital-grade cleaning agents and are the usual specification where cleanability is a clinical requirement. Prelaminated particle board, veneer and lacquered glass are maintained as any comparable interior finish. The advantage over a painted drywall partition is that a damaged panel is a replaceable component: a single panel can be lifted out and a new one fitted, without patching, sanding, repainting a whole wall face, or matching a paint batch.

There is no fixed limit; the practical constraint is the condition of the components rather than a cycle count. Frames are aluminium and do not degrade with dismounting, and panels are retained on hooks or clips rather than face-fixed, so removal does not damage the panel face. Screw holes in floor and ceiling remain from the previous position and are made good as part of the reinstallation.

The remedial work is minor and confined to fixing points. Posts are fixed to floor and structural soffit with screws, so removal leaves fixing holes to be filled — not the demolition scar, debris stream and repainting of adjacent finishes that removing a drywall partition produces. Flooring and ceiling systems either side are undisturbed, since the partition is not bonded to them.

Yes, through several distinct routes. Certified low-impact products contribute to materials and resources credits under LEED and WELL internationally, IGBC and GRIHA in India, BREEAM in the UK and Europe, and Green Star in Australia. Recycled content in the aluminium frame contributes separately. And demountability itself contributes in a way fixed construction cannot: a partition relocated rather than demolished avoids both the construction waste stream and the embodied carbon of manufacturing its replacement. All three IQUBX demountable partition systems — WP03P, WP01P and WP02P — carry GreenPRO Ecolabel Type 1 certification from the Products and Services Council of India and are manufactured from 6063 T6 aluminium with up to 100% recycled content.

An IQUBX lifecycle simulation study modelled a 50,000 sq ft commercial office over ten years and found WP03P generated 150.5 tCO₂e against 309.7 tCO₂e for a conventional fixed solid partition system — a reduction of 51.4%. The saving arises less from manufacturing than from what does not happen afterwards: no demolition waste stream at each reconfiguration, no replacement material to manufacture and transport, and recovery of the aluminium frame at end of life.

Yes. IQUBX designs and manufactures in India and supplies to projects domestically and internationally, with completed projects in the UAE, Bahrain, Oman and Nepal, and availability for international supply globally. The system architecture suits export particularly well because only the aluminium framing ships: posts and rails travel knocked down and containerise efficiently, while panels are sourced locally at destination from any sheet material within the system’s thickness range. Freight cost, lead time and shipping-related carbon all fall accordingly.

Frequently Asked Questions — WP03P

What is IQUBX WP03P?

WP03P is IQUBX’s demountable solid partition wall system, built on a 6063 T6 aluminium post-and-rail frame — 44×50mm post, 60×9mm rail, 25×10mm hook section — with a 26mm continuous vertical service cavity and tool-free removable panels. It is the flagship of the IQUBX partition range and the only one of the three systems with a certified acoustic rating: STC 51 in its tested configuration. Its three defining capabilities are the continuous service cavity, certified acoustic performance, and 51.4% documented lifecycle carbon reduction against conventional fixed partitions.

WP03P achieves STC 51 in its standard minimum configuration: 12mm prelaminated particle board panels on both faces, continuous EPDM perimeter seals, and polywool or rockwool insulation in the cavity. The test was conducted at the Research Department of All India Radio and Doordarshan, Prasar Bharati, Government of India. The rating is specific to that tested configuration — a documented result for a defined build-up, not a marketing ceiling.

Yes. STC 51 is the certified figure for the minimum configuration, and performance rises with mass and cavity treatment. Increasing panel thickness to 18mm or 25mm prelaminated particle board raises the assembly’s mass and improves low-frequency performance; adding mass-loaded vinyl within the cavity, increasing insulation density, or specifying an intermediate buffer in a thicker partition build-up all contribute further. For projects requiring performance above STC 51, IQUBX’s specification team advises on the build-up.

They are the reason WP03P holds a certified rating and WP01P does not. Continuous EPDM gaskets run along the full perimeter of every panel — top, bottom and both sides — compressing against the frame to close the air path at every panel edge. Airborne sound follows any air path, so an unsealed panel perimeter leaks sound regardless of how much mass the panel carries. The gasket line is what converts a well-built partition into a tested acoustic assembly, and it is the single most significant technical difference between WP03P and the rest of the range.

26mm, continuous vertically through the full height of the partition at every point along its length. The dimension is set so that a 25mm OD conduit passes through freely. The cavity accommodates electrical conduits, switchboard boxes, data cabling and light plumbing, and can be expanded by joining two posts through the thickness where a deeper services zone is required. Because it is continuous rather than interrupted by studs, a services run can be introduced at any point after installation rather than only where a route was left during construction.

Yes. Conduits drop into the continuous cavity between the two rail rows and run the full height of the partition. Because the panels are removable from either face without tools, a new circuit can be added, an existing one traced, or a faulty run replaced by lifting the panels covering that section — no cutting, no core drilling, no making good, no repainting. In a conventional drywall partition the same operation requires opening the board face and reinstating the finish.

Yes — this is fundamental to the system rather than an accessory feature. Panels are retained on a hook section (WP03Pc, 25×10mm) that clips onto the rail, allowing removal from either face without tools and without disturbing the frame, adjacent panels, or the services within the cavity. A panel can be replaced for damage, changed for a different material or finish, or lifted temporarily for service access and refitted.

Any sheet material from 6mm to 25mm thickness — the widest range in the IQUBX partition family. In practice: HPL at 6mm for maximum durability and clinical cleanability; prelaminated particle board at 12, 18 or 24mm as the most widely specified and the material used in the STC 51 test; natural veneer on board backing where the warmth and prestige of real wood is wanted; lacquered back-painted glass at 4–6mm on MDF, HDF or HDHMR backing, which doubles as a writing surface; soft board and cork board for pinboard and acoustic absorption; and perforated or grooved acoustic panels in PET, perforated metal or wood, and fibre boards. Panels are sourced and prepared locally, which shortens lead time and reduces both cost and transport footprint.

75mm is the standard configuration: 50mm framing including the 26mm cavity, with 12mm panels on both faces. A 100mm configuration is available using an intermediate buffer, which increases the services zone and improves low-frequency acoustic performance. Overall thickness ranges from 76mm to 104mm depending on panel selection and framing arrangement.

WP03P accommodates groove widths from 2mm to 12mm. A zero-groove finish should never be specified, and the reason is optical rather than mechanical.

The panels in this system float. They are held on a hook section rather than screwed, nailed or bonded to the frame, which is precisely what makes them removable — but it also means each panel sits with a very small amount of positional freedom. Across a run of panels this produces micro-misalignments between adjacent edges, and micro-imbalances in the plane of the surface. Neither is a defect; both are inherent to any floating panel system. The groove is what absorbs them. At 2mm and above, the shadow line reads as a deliberate joint and the eye stops registering the tiny variations within it. At zero groove, panel edges meet directly and every one of those micro-variations becomes visible as an irregular line. 2mm is the working minimum.

Above 2mm, groove width becomes a design decision rather than a technical one. Most architects prefer 6mm on aesthetic grounds — it reads as a deliberate, well-proportioned shadow line without exposing the frame within the joint. Grooves need not be uniform across a partition: because hook positions can be varied, different groove widths can be used in different locations within the same wall, and designers frequently use non-uniform or deliberately patterned groove rhythms as a compositional device. At 12mm the frame becomes visible within the groove and must be powder-coated or anodised to an aesthetic standard. Grooves should never be filled with putty, filler or strips — doing so defeats the modularity the system exists to provide.

A narrow groove does not prevent removal. It changes the sequence.

Disengaging a WP03P hook laterally — lifting a single panel straight out of the middle of a wall without touching its neighbours — needs a 9mm groove to give the hook room to clear. Many projects do not want a 9mm shadow line; beyond 2–3mm the joint starts to become a visual feature that some schemes would rather not have. Where the design calls for a tighter groove, panels are removed from the top down instead.

This works because of a detail that is already part of the standard installation: the junction between the partition head and the ceiling carries a shadow groove of around 12mm minimum. That gap gives the topmost panel the clearance it needs to disengage. Once the top panel is out, the panel below it has an opening to move into, and removal proceeds downward one course at a time. Reinstallation reverses it. The operation takes marginally longer than lifting a single panel out of the middle of a wall, and it is not a constraint on the design.

So the groove is an aesthetic decision, not an access one. A 2mm partition remains fully serviceable.

Vertical posts are typically set at 600–750mm centre to centre, with 900mm treated as a practical maximum. The optimal spacing is governed by the stiffness of the chosen panel: a thicker, stiffer skin such as 18–24mm prelaminated particle board resists mid-span deflection and permits wider spacing with correspondingly less framing material, while a thinner 12mm skin calls for closer posts. Because a thicker panel also raises the assembly’s mass and therefore its sound insulation, panel thickness and post spacing are best resolved together rather than separately.

Genuinely nail-less. Panels are retained on a concealed hook section rather than face-fixed with screws or nails, so there are no visible fasteners and no surface damage to the panel face during installation or subsequent removal. This is what makes pre-finished veneer panels practical: they are prepared and finished in a workshop and installed dry, with no site polishing, no filling of fastener heads and no touch-up.

Yes, and the system is designed for it. Frames are partly assembled in the workshop and shipped knocked down for compact transport; panels are prepared, veneered, edge-banded or glass-backed offsite and arrive finished. On site, posts are fixed floor to soffit, rails go on, services are run in the open cavity, and panels are hooked on one face and then the other. There are no wet trades and no drying times, so the sequence can be phased and interleaved with other site activity rather than blocking it.

Yes. Relocation reverses the installation sequence: panels are removed, services are withdrawn from the cavity, rails and posts are dismantled, and the components are transported and reassembled in the new layout. IQUBX records in excess of 95% remounting success, the small balance being panels cut to non-standard sizes for the original configuration. Screw holes at the previous floor and ceiling positions are made good; there is no demolition, no debris stream, and no replacement material to manufacture.

Substantially faster, because the construction is dry and modular. There are no wet trades and no drying times, frames can be pre-fabricated in the workshop and panels arrive pre-finished, and installation proceeds as a single trade rather than the sequence of framing, boarding, taping, sanding, priming and painting that conventional partition construction requires. The saving is not only in days but in sequencing: services can be installed after the frame is up and before the second face is panelled, rather than being buried during construction.

From around ₹500 per square foot installed (about USD 5.20) in India, excluding taxes and shipping. That is the starting rate for the minimum standard configuration — 12mm prelaminated particle board on both faces, rockwool or polywool cavity infill at ₹20–25 per sq ft, posts at 600mm centres and rails at 750–900mm spacing — and it includes framing, panels, insulation, labour, installation and normal contractor margin. It is a floor, not an average.

The component breakdown: IQUBX framing ₹150–300 per sq ft (USD 1.56–3.13), panels ₹75–200 per sq ft of panel (USD 0.78–2.08), and labour with on-site installation ₹40–100 per sq ft (USD 0.42–1.04). Transport, contractor fees and taxes are additional and project specific.

Panels are not an IQUBX product. They are specified by the design team and sourced locally, and the rates above are market rates for finished, installation-ready panels — raw sheet, cut to the grid sizes, edge-banded. Prelaminated particle board arrives at roughly ₹75 per sq ft finished; veneered ply, perforated acoustic panels and cork on HDF sit well above it.

Specification decisions move the rate substantially. Upgrading the panel face to natural veneer or lacquered back-painted glass increases the panel line several times over. Specifying for acoustic performance above the certified STC 51 adds panel thickness and cavity treatment. Intricate groove patterns, close post spacing and complex junction detailing add both framing and labour.

An IQUBX simulation study modelled a 50,000 sq ft commercial office over ten years and found WP03P generated 150.5 tCO₂e against 309.7 tCO₂e for a conventional fixed solid partition system — 51.4% lower. The frame is manufactured from up to 100% recycled 6063 T6 aluminium (10% pre-consumer, 90% post-consumer), and the system carries GreenPRO Ecolabel Type 1 certification.

WP03P occupies a distinct technical position in three areas. The continuous service cavity is a primary design commitment rather than an option, where competing systems generally treat service integration as an accessory. The STC 51 rating is documented for a specific tested configuration at a named Government of India laboratory, where premium brands more commonly publish an “up to” figure without stating the configuration it was achieved in. And the lifecycle carbon reduction is a published figure — 51.4%, 159.2 tCO₂e — where competitors typically publish sustainability positioning without a comparable number. Panel material freedom across the full 6–25mm range is also broader than systems restricting specification to a proprietary panel catalogue.

Yes, with completed projects in the UAE, Bahrain, Oman and Nepal and availability for supply internationally. Only the aluminium framing ships — posts and rails travel knocked down and containerise efficiently — while panels are sourced locally at destination from any material in the 6–25mm range. The GreenPRO Ecolabel Type 1 certification and documented lifecycle carbon performance contribute to green building credits under LEED, WELL, BREEAM, Green Star, Estidama and GSAS.

Frequently Asked Questions — WP01P

What is IQUBX WP01P?

WP01P is a demountable paneling partition system created by doubling the WP01 wall paneling system into a partition configuration. It uses a 6063 aluminium post-and-rail frame — 50×44mm post, 12×53mm rail with integral hook, 5×22mm hook section — with a 25mm continuous vertical service cavity and panels retained on lock clips that snap onto the rails. Its particular value is visual continuity: where a project uses WP01 wall paneling, WP01P delivers partitions in exactly the same panel language, groove rhythm and material palette, so a wall and a partition in the same room read as one system rather than two.

The continuous EPDM gaskets, and a set of consequences that follow from the different derivation of the two systems.

WP03P carries continuous EPDM gaskets on all four perimeter edges of every panel, which seals the air path at each panel edge and delivers its certified STC 51 rating. WP01P has no gasket line and no certified acoustic rating. That is the primary difference.

The secondary differences are dimensional and mechanical. WP01P’s cavity is 25mm against WP03P’s 26mm. Its panel range is 6–18mm against 6–25mm, so the heaviest panel build-ups available in WP03P are not available in WP01P. Panels are held by lock clips that snap onto the rail, where WP03P uses a separate 25×10mm hook section. The recommended groove is 4–12mm against WP03P’s 2–12mm. And the post and rail sections themselves differ: 50×44mm post with a 12×53mm rail in WP01P, against a 44×50mm post with a 60×9mm rail in WP03P.

Specify WP03P where a project specification names an STC figure. Specify WP01P for general office partitioning, and particularly where WP01 wall paneling appears elsewhere in the same interior.

No. STC 51 is certified for WP03P only, tested at the Research Department of All India Radio and Doordarshan, Prasar Bharati. WP01P is not gasketed on the panel perimeter and has not been separately tested, so no STC figure should be claimed or specified for it. WP01P does carry a continuous 25mm cavity that accepts acoustic insulation, which contributes to sound attenuation — but attenuation without a test certificate is not a rating, and specifying it as one exposes a project to a compliance failure. Where a project specification names a required STC figure, specify WP03P.

A uniform vertical and horizontal groove between 4mm and 12mm is the recommended working range, with 2–3mm the absolute minimum — the same minimum that applies to WP03P. The reason 4mm heads the recommended range is that 4mm is the clearance a WP01P panel needs to be disengaged and lifted out in place, so a groove at or above it keeps every panel individually removable without touching its neighbours.

The reason for the minimum is the same in both systems and is optical rather than mechanical. WP01P panels float on lock clips rather than being screwed or bonded, so each panel sits with a small amount of positional freedom. Across a run this produces micro-misalignments between adjacent panel edges and micro-imbalances in the surface plane — inherent to any floating panel system, not a defect. The groove absorbs them: at 2mm and above the shadow line reads as a deliberate joint and the eye stops registering the variation within it, while at zero groove every micro-variation shows as an irregular line where edges meet.

Above the minimum, groove width is a design decision. Hook positions can be varied, so different groove widths can be used in different locations within the same partition rather than one dimension applied throughout.

A zero-groove or flush finish should never be specified in either system.

No. As with WP03P, a narrow groove changes the removal sequence rather than preventing removal — and WP01P needs less clearance than WP03P to begin with.

Lifting a single WP01P panel laterally out of the middle of a wall needs a 4mm groove. This is less than half the 9mm WP03P requires, because the WP01P hook-and-rail arrangement is shallower — the rail carries an integral hook at 12×53mm and the hook section is only 5×22mm, against WP03P’s separate 25×10mm hook. Less hook depth means less clearance needed to disengage it.

Where a project specifies a groove below 4mm for appearance, panels are removed from the top down. The partition head carries a shadow groove of around 12mm minimum at the ceiling junction, which gives the topmost panel room to disengage; once it is out, each panel below has somewhere to move into and removal proceeds downward. Reinstallation reverses the sequence.

Panels are retained on lock clips that snap onto the rails, and they come off and go back on at any time. This gives two distinct functions: services within the cavity can be reached and maintained without cutting the wall, and a panel can be changed for damage, repair, or a different material or finish without disturbing the frame or its neighbours. The fixing is concealed, so there are no visible fasteners and no surface damage to the panel face.

Rails are fixed to the posts from the front with screws, with no brackets required. This is a meaningful practical difference: bracket-based frame systems require a separate component and a separate operation at every post-and-rail junction, and a partition frame contains a great many of those junctions. Screwing from the front removes both, which is why WP01P frames go up quickly. Rails can be positioned in any configuration the design calls for rather than at fixed bracket positions.

25mm continuous vertical cavity between the rails in the standard 75mm partition. The cavity carries electrical conduits and services, which can be added or modified at any time by removing panels, and it takes continuous acoustic insulation through the full height of the partition.

Yes. The 100mm variant uses two post frames with a 25mm buffer channel between them, producing a 50mm cavity rather than the standard 25mm. The particular flexibility this offers is that an additional tube can be introduced between the two WP01 frame components, which opens up configuration options within the partition thickness.

This is a specific advantage in a specific situation, not a general reason to prefer WP01P. Where the requirement is a partition with certified acoustic performance, a wider panel range or the full service-integration design commitment, WP03P remains the stronger system on every one of those counts.

6mm to 18mm, with 12mm typical. Materials include edge-banded prelaminated particle board, MDF, veneered ply, soft board and glass on ply backing. The upper limit of 18mm is the practical distinction from WP03P, which takes up to 25mm — so the heaviest panel build-ups, and the additional mass they contribute to sound insulation, are available only in WP03P. As with the rest of the range, panels are sourced and prepared locally rather than shipped as part of the system.

75mm standard: 50mm framing including the 25mm cavity, with 12mm panel skins on both faces. A 100mm variant is available using a 25mm buffer channel between two post frames, which increases the services zone to 50mm and adds mass to the assembly.

That is precisely where it comes from. WP01P is the WP01 wall paneling system doubled into a partition configuration — rails fixed to both faces of the posts rather than one — so the two share their panel modules, groove rhythm, clip fixing and material palette. In a single-face application the system panels a wall; in a double-face application it becomes a partition with a service cavity between the rail rows. For an interior where both are required, this is the cleanest way to get visual continuity between a clad wall and a freestanding partition.

The load path runs through the frame, not the panels. The posts are the load-bearing members, fixed floor to structural soffit, and the rails carry the panels. Where a wall-mounted television, shelving, cabinetry or a service unit is to be fixed, the position should be identified at design stage so that additional posts or channels are placed to receive it. Because the panels lift off, a fixing position can be verified and adjusted before the panel goes back on.

Yes. The frame dismantles and the panels lift off their clips, so the system comes down, transports and reassembles in a new layout without demolition or a debris stream. The aluminium frame does not degrade with dismounting, and panels held on clips rather than face-fixed are not damaged by removal. Because rails are screwed to the posts from the front rather than bracketed, dismantling is also faster than reassembling a bracket-based frame.

WP01P costs broadly the same as WP03P — expect a variation of around 10% either way against the WP03P base rate of approximately ₹500 per square foot installed in India (about USD 5.20), excluding taxes and shipping. The framing architecture is comparable and the panel and labour lines behave the same way.

Two things pull the WP01P rate slightly below WP03P: the absence of the continuous EPDM gasket removes a cost element, and the front-screwed rail connection reduces assembly labour. One thing narrows the saving: the 6–18mm panel range excludes the thicker, less expensive-per-unit-mass build-ups that WP03P can use. Where a project does not require certified acoustic performance, WP01P delivers the post-and-rail system with its continuous service cavity and removable panels at a marginally lower rate.

Frequently Asked Questions — WP02P

What is IQUBX WP02P?

WP02P is a snap-fit paneling and partition system: WP02 snap-fit mouldings applied to both faces of a lightweight frame. It is a panel-fixing system rather than a framing system, so the frame itself can be aluminium tube, timber, IQUBX OFRS, mild steel, or fabricated locally. The assembled snap-fit section measures 14×15mm, with a 14×13mm top channel — 14mm visible from the front, comprising 5mm flanges and a 4mm groove — and a 24×9mm base plate. It accepts any panel material between 10mm and 12mm and is the fastest system to install in the IQUBX range.

In excess of 1,000 square feet per day of cladding, equivalent to approximately 500 square feet of straight panel partition with two workers. That figure assumes straight runs without design complexity and varies with pattern, panel material and site conditions. The speed comes from the fixing method: a base channel is screwed to the substrate along one edge, and pre-sized panels snap into the grid without hooks, adhesives or face fixings.

WP02P is a fixing system, not a framing system — that is the fundamental difference. WP03P and WP01P are engineered post-and-rail frames that create the partition structure and carry the panels. WP02P supplies only the snap-fit grid and relies on a separate frame, which can be built from whatever is locally available. This makes WP02P faster and more materially flexible, but it means the system has no inherent service cavity unless the double-frame option is used, and no gasketed acoustic seal. Choose WP03P or WP01P for engineered partition structure; choose WP02P for speed, cladding, and panel material freedom.

No — and its acoustic behaviour is panel-dependent rather than a system property. Because WP02P is derived from the WP02 paneling system, sound performance follows entirely from the panel material specified, and the relevant measure is generally NRC (surface absorption) rather than STC (transmission between rooms). Any STC contribution depends on the frame construction and cavity treatment beneath. WP02P is best suited to spaces with moderate acoustic requirements. Where a specification names an STC figure, specify WP03P.

Any material between 10mm and 12mm, and the range is wider than the other two systems because no hooks are fixed to the back of the panel. That opens the system to gypsum board, calcium silicate, mineral tiles, GRG and PVC, alongside glass, prelaminated particle board, veneer and soft board. Materials that cannot accept a back-fixed hook — which rules them out of WP03P and WP01P — work in WP02P because the panel is held at its edges by the snap-fit grid.

Yes, in one specific and useful respect: panel material freedom. Because WP02P holds panels at their edges rather than on back-fixed hooks, it accepts gypsum board, calcium silicate board and mineral tiles at 10–12mm as standard. These are precisely the non-combustible and near-non-combustible panel materials specified where fire load is a concern, and WP02P accommodates them without special provision. The system itself carries no fire resistance rating and should not be specified where code requires a rated assembly; the advantage is that its material openness makes a low-fire-load panel specification straightforward.

Yes, and this is one of its principal applications. The base channel fixes with screws to any substrate, so WP02P can clad an existing masonry wall, drywall partition, or previously installed partition frame, converting a tired or damaged surface into a demountable, panel-changeable finish without demolition. It also installs onto purpose-built or prefabricated frames where a new partition is required.

Yes, using the double-frame option. Two light frames — for example 20×20mm tubes — are interlocked at the nodes with a 25mm gap between them, with WP02 paneling applied to both outer faces. The result is a hollow partition with a service cavity between the frames, giving WP02P the conduit routing and acoustic insulation capability of the post-and-rail systems while retaining the snap-fit installation speed.

Yes. Any panel can be released and replaced at any time — for a change of material or finish, for repair, or for maintenance access behind. Because panels are held at their edges by the snap-fit grid rather than fixed through their faces, removal leaves no marks and the replacement panel needs no preparation beyond being cut to size.

Yes. The panels and the WP02 snap-fit system move easily — panels release from the grid, mouldings unscrew from the substrate, and both reinstall elsewhere without demolition or a debris stream.

What WP02P cannot determine is the fate of anything that was never part of the system. WP02P is a panel-fixing system applied to a separately built frame, existing wall or existing partition, and those elements remain subject to their own nature: a demountable aluminium tube or OFRS frame comes down with the panels, while a masonry wall or built-in construction does not. Specify the substrate accordingly and the whole assembly relocates.

WP02P is the most cost-variable system in the range, because the snap-fit channel is inexpensive and the panel choice is unusually wide. Expect roughly ₹100 to ₹530 per square foot (USD 1.05 to 5.50) depending almost entirely on panel material, excluding taxes and shipping.

Taxes are additional. A gypsum-faced WP02P partition sits at the bottom of the range and is the most economical demountable option IQUBX offers; a veneered ply or lacquered glass face sits at the top and is comparable with a specified WP03P partition. Because the framing beneath WP02P can be built from locally available material — aluminium tube, timber, mild steel or IQUBX OFRS — the frame cost also varies with what is specified and sourced locally.

Three situations. Where a project specification names an STC figure, because WP02P has no certified acoustic performance and its behaviour depends on panels and frame rather than on the system. Where code requires a fire-rated assembly, because no IQUBX system is rated. And where the partition must be fully relocatable as an engineered unit, because WP02P depends on a frame it does not supply. In each of those cases specify WP03P, or WP01P where certified acoustics are not required.
