Question 1

What is a demountable partition wall?

Accepted Answer

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.

Question 2

What is the difference between a demountable partition and a movable (operable) partition?

Accepted Answer

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.

Question 3

What is the difference between a demountable partition and a gypsum drywall partition?

Accepted Answer

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&#8217;s reconfiguration cycles, because the second, third and fourth changes are near-free where drywall charges full price every time.

Question 4

Which IQUBX system should I choose - WP03P, WP01P or WP02P?

Accepted Answer

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.

Question 5

What is the difference between NRC and STC?

Accepted Answer

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&#8217;s choice at panel stage rather than a fixed system property.

Question 6

What STC rating does an office actually need?

Accepted Answer

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.

Question 7

How is sound leakage above a false ceiling prevented?

Accepted Answer

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&#8217;s rated performance. To preserve a rated partition&#8217;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.

Question 8

Are IQUBX demountable partitions fire rated?

Accepted Answer

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.

Question 9

How can fire risk be reduced in a non-rated IQUBX partition?

Accepted Answer

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.

Question 10

How much do demountable partitions cost per square foot?

Accepted Answer

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:

Cost component	Typical range (₹/sq ft)	USD equivalent
IQUBX aluminium framing	150 – 300	1.56 – 3.13
Panels — locally sourced, per sq ft of panel	75 – 200	0.78 – 2.08
Acoustic infill — rockwool or polywool	20 – 25	0.21 – 0.26
Labour and on-site installation	40 – 100	0.42 – 1.04
Transport / shipping	project specific	project specific
Contractor margin and fees	project specific	project specific
Taxes	extra	extra

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.

Question 11

Which cost variables move the rate most?

Accepted Answer

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.

Question 12

Do demountable partitions qualify for accelerated tax depreciation?

Accepted Answer

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&#8217;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.

Question 13

Can demountable partitions carry loads such as wall-mounted televisions or shelving?

Accepted Answer

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.

Question 14

Are demountable partitions secure?

Accepted Answer

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.

Question 15

Can demountable partitions be installed in an occupied office?

Accepted Answer

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.

Question 16

How are demountable partitions cleaned and maintained?

Accepted Answer

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.

Question 17

How many times can a demountable partition be relocated?

Accepted Answer

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.

Question 18

What happens to the floor and ceiling when a demountable partition is removed?

Accepted Answer

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.

Question 19

Do demountable partitions contribute to green building certification?

Accepted Answer

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.

Question 20

What is the carbon footprint of a demountable partition compared with a conventional one?

Accepted Answer

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.

Question 21

Are IQUBX demountable partitions available outside India?

Accepted Answer

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&#8217;s thickness range. Freight cost, lead time and shipping-related carbon all fall accordingly.
