Commercial office partitioning sits at the intersection of acoustics, aesthetics, flexibility and budget. This guide compares the five main system categories on performance, price, reconfig potential and installation time.
Partitioning is typically 15–22% of a CAT B fit-out budget — the single biggest line item after M&E. The system choice locks in acoustic performance, future flexibility, aesthetic and replacement cost for the life of the fit-out. A poor choice locks in disruption for the entire lease term.
Plasterboard face on steel-stud frame. Removable and reconfigurable. Rw 42–48. Affordable. Best for budget-constrained fit-outs and spaces requiring future change.
10–12mm glass with minimal frame. Transparent, modern, aesthetic. Rw 35–42 (lower acoustic performance). Best for open-plan-edge meeting rooms where visual transparency matters more than acoustic isolation.
Two panes with air or insulated cavity. Rw 45–52. Premium aesthetic with strong acoustic performance. Best for boardrooms and confidential-meeting spaces.
Veneered timber panels with integrated glazed openings. Rw 48+. Highest aesthetic. Best for executive offices and trophy spaces.
Bespoke multi-layer systems with acoustic-grade glazing, drop seals, thermal breaks. Rw 55–62. Best for hearing rooms, legal confidentiality, executive dictation rooms.
| System | Rw | Cost / linear m | Install time |
|---|---|---|---|
| Demountable solid | 42–48 | £140–£240 | 6 weeks typical |
| Single-glazed frameless | 35–42 | £380–£550 | 3–4 weeks |
| Double-glazed acoustic | 45–52 | £650–£900 | 4–5 weeks |
| Executive timber + glazed | 48+ | £900+ | 5–7 weeks |
| Specialist Rw 55+ | 55+ | £1,200+ | 6–8 weeks |
The partitioning market is dominated by 6–8 major system houses. Preference notes:
Demountable solid for enclosed rooms; single-glazed frameless for visibility-critical rooms. Rw 42–45 performance, typical cost £180–£300 per linear metre blended.
Double-glazed for boardrooms; demountable solid with slab-to-slab detailing elsewhere. Rw 48+ throughout. Cost £400–£600 per linear metre blended.
Frameless glazed plus executive timber-veneer for key rooms. Premium finish throughout. Cost £600–£900+ per linear metre blended.
All-demountable throughout (no plasterboard skim; separate joinery for aesthetics). Future reconfig at 20–30% of original cost. Specify at appointment stage.
For Rw to be realised, partitions must meet slab, not ceiling grid. Ceiling-grid-only partitions leak sound through the void.
Door acoustic rating matters as much as wall. Specify matched Rw door-sets with drop seals and acoustic gaskets.
Every cable, duct or socket penetrating a partition needs acoustic lagging or in-line attenuation.
Sound flanks around partitions via ceiling void, floor void, and perimeter walls. Acoustic baffles in the ceiling void between adjacent rooms are standard on premium fit-outs.
Our Office Partitioning service covers all five categories and works with all major system houses. We self-deliver installation under occupancy with typical night-shift completion of 2 hours per linear metre installed.
Limited retrofit options: adding acoustic door-seals (drops Rw back toward spec), adding acoustic baffles in ceiling void, upgrading glazing. Full acoustic re-performance almost always requires replacement.
Demountable adds 20–30% to initial cost but saves 60–70% on first reconfig. Break-even is typically 2–3 reconfigs over lease term.
Yes — most systems offer graded Rw packages within the same visual range (e.g. Rw 38 / Rw 45 / Rw 52 in the same glazed aesthetic). Specify room-by-room performance.
