For decades, drywall has been the default solution for dividing up office space. But in today’s world of constant change, drywall feels outdated. It’s messy, inflexible, and wasteful. Every time a company grows, restructures, or redesigns, drywall ends up in dumpsters costing money, creating downtime, and adding to environmental impact.
Forward-thinking firms are moving beyond drywall. With feco partition wall systems, you get modular, precise, and reusable solutions that transform office renovation into a smarter, greener process.
What Are Demountable Office Walls?
Demountable office walls are modular partition systems designed to be installed, disassembled, and reinstalled without generating construction debris. Unlike drywall - which is bonded to metal stud framing with screws and compound and cannot be removed without being destroyed - demountable systems use mechanical connections that allow panels to be separated and relocated.
Demountable systems are available in solid, glass, and combination configurations. They accommodate integrated doors, electrical outlets, data ports, and glazing. Acoustically, high-performance demountable systems from manufacturers like feco achieve independent tested ratings that meet or exceed typical drywall construction.
In the Canadian market, demountable walls are most commonly specified in:
•      Technology, finance, and professional services offices with frequent headcount and team changes.
•      Co-working and flexible workspace operators who reconfigure spaces for new tenants.
•      Corporate headquarters pursuing LEED certification or ESG waste reduction targets.
•      Tenants with 3-7 year leases who anticipate at least one significant layout change during occupancy.
The Real Cost Comparison: Drywall vs Demountable
The standard objection to demountable systems is cost: they cost more upfront than drywall. This is true. The relevant question is whether this upfront premium is recovered through lower lifecycle costs - and for most Canadian commercial tenants, it is.
Upfront Cost
As a directional market estimate (unverified - confirm with local contractors for your specific project):
•      Standard drywall partition construction: $35-$65 per linear foot installed (framing, drywall, tape, prime, paint).
•      Mid-range demountable partition system: $90-$160 per linear foot installed (system panels, hardware, integration).
•      Premium glass demountable system (e.g., feco): $180-$350+ per linear foot installed depending on configuration.
At face value, drywall appears to be the lower-cost choice by a significant margin. The full picture requires accounting for what happens when layout changes.
Reconfiguration Cost
A single office reconfiguration involving 100 linear feet of wall repositioning in a Canadian commercial office:
•      Drywall demolition and rebuild: $25,000-$60,000 (demolition labour, disposal, rebuild framing, drywall, finishing, painting, permit if required). This cost is incurred in full on every reconfiguration.
•      Demountable system reconfiguration: $8,000-$20,000 (disassembly, reinstallation, potential additional panels if layout expands). Materials are preserved and reused.
For a tenant with a 7-year lease who undergoes one reconfiguration at year 3 and another at year 6, the demountable system recovers its upfront premium entirely through reconfiguration savings alone - and produces significantly less construction waste.
A drywall reconfiguration costs money and creates waste. A demountable wall reconfiguration costs less money and creates none. This is the entire financial argument.
Acoustic Performance: The Misconception
The most common concern about demountable partition systems is acoustic performance: can modular panels really match drywall for sound isolation?
For mid-range and premium demountable systems, the answer is yes - and in some configurations, they exceed standard drywall construction.
Standard drywall partition (single layer each side, standard batt insulation): typically achieves STC 35-40 in practice. Double-layer drywall with resilient channel: STC 45-50 in laboratory conditions, typically lower in field installation.
feco glass and solid partition systems achieve Rw ratings (the European equivalent of STC) of 40-52 depending on configuration, independently tested to ISO 10140 standards. The Rw 52 acoustic configuration uses laminated glass with offset panel joints and sealed perimeter details.
For boardrooms, HR offices, legal conference rooms, and executive suites - where speech privacy is a compliance and confidentiality requirement, not just a preference - the acoustic performance of quality demountable systems is fully adequate.
Note: budget-tier demountable systems with thin panels and unsealed perimeters do not achieve these ratings. Specify systems with independent acoustic test data, not manufacturer claims alone.
Sustainability: The ESG and LEED Dimension
Canadian corporate real estate decisions increasingly involve sustainability criteria, driven by tenant ESG commitments, LEED certification requirements, and corporate net-zero targets.
Demountable partition systems contribute to sustainability outcomes in two ways:
Waste Reduction
Drywall construction generates substantial waste during initial fit-out (cutting waste, scrap material) and again at reconfiguration or lease end, when the material typically goes to landfill. In Canada, construction and demolition waste accounts for approximately 25-30% of total solid waste by weight (Canada Green Building Council, Verified).
Demountable systems generate minimal waste during installation (no cutting, no compound, no disposal) and effectively zero waste at reconfiguration (panels are reused). This directly reduces a project's contribution to construction waste streams.
LEED Credits
Under LEED v4.1 for Interior Design and Construction, demountable partition systems can contribute to Materials and Resources credits in two categories: Building Product Disclosure and Optimization (for products with verified environmental data) and Construction and Demolition Waste Management (for reducing site waste). Confirm specific credit eligibility with your LEED consultant.
Benefits by Stakeholder
Business Owners and CEOs
Demountable systems reduce the total cost of occupancy over the lease term and eliminate the operational disruption of full demolition-and-rebuild renovation cycles. A layout change that would require 6-8 weeks of construction with drywall takes 1-2 weeks with demountable systems, with significantly less dust, noise, and employee disruption.
Facilities Managers
Demountable systems allow incremental reconfiguration in response to organizational changes without triggering a full renovation project. Small changes - relocating a wall by 3 meters, adding a private office from an existing open area - can often be completed within existing maintenance budgets.
Architects and Interior Designers
Demountable systems provide design precision that site-built drywall cannot match. Panel dimensions, finishes, and integration of glazing and electrical elements are factory-engineered to tolerances that field-built construction cannot consistently achieve.
Landlords and Property Developers
Tenants who install demountable systems leave the space in a condition that is easier to re-let. The partition system has known specifications and can be assessed, retained, or reconfigured for the next tenant. Drywall in a vacated space must be assessed for damage, patched, repainted, or demolished - at the landlord's cost or the outgoing tenant's.
Frequently Asked Questions
Are demountable walls more expensive than drywall?
Upfront, yes. Demountable partition systems typically cost $90-$160+ per linear foot installed versus $35-$65 for standard drywall. However, over a 5-10 year Canadian commercial lease with at least one reconfiguration, demountable systems typically achieve lower total cost of ownership because reconfiguration costs are dramatically lower and materials are preserved rather than discarded.
How do demountable walls perform acoustically compared to drywall?
High-performance demountable systems from manufacturers like feco achieve acoustic ratings of Rw 40-52 in independently tested configurations. Standard drywall partitions achieve STC 35-40 in practice. Quality demountable systems fully meet the acoustic requirements of boardrooms, private offices, HR spaces, and legal conference rooms.
Can demountable walls be removed at the end of a Canadian commercial lease?
In most cases, yes - and this is one of their advantages. Unlike drywall, which must be demolished and disposed of at lease end (generating cost and waste), demountable systems can be disassembled and relocated to a new space, sold, or retained by the landlord. Confirm your specific lease provisions with your lawyer before making this assumption.
What is the installation timeline for demountable walls versus drywall?
Demountable systems are factory-engineered and installed using mechanical connections without wet trades (no compound, no paint, no drying time). Installation is typically 30-50% faster than drywall for equivalent linear footage. A 100-linear-foot demountable installation can often be completed in 2-3 days by a trained crew versus 2-3 weeks for equivalent drywall construction.
