Combined thermal and acoustic performance, inside the wall
WallSHIELD is dense-packed into wall and partition cavities before the board goes on, filling the cavity completely. The result is one integrated solution for better thermal and acoustic performance between spaces.
Put your walls to work
Privacy between spaces
Meeting rooms, hotel rooms, consulting rooms and executive offices — WallSHIELD adds sound-absorbing insulation within drywall cavities, helping support better acoustic separation as part of a properly designed partition assembly.
Two problems, one trade
Thermal and acoustic performance delivered through a single insulation installation, sequenced once in the programme.
Conforms to the cavity
Dense-pack flows around studs, noggings, conduit, boxes and pipework — helping minimise gaps around framing and services behind the board.
Designed to resist settling
Installed at density rather than laid in — dense-pack installation helps maintain consistent cavity coverage over time.
Designed for framed walls
Non-corrosive to steel studs and fixings, and borate-treated against mold and pests in a permanently enclosed cavity.
Fast on programme
Installed into open framing before boarding, in a single visit — so WallSHIELD is coordinated with the drywall contractor's installation sequence.
Where WallSHIELD performs
Acoustic & thermal data
IFI cellulose, tested to ASTM C423 on solid backing. Performance varies with installed thickness and the complete wall assembly; final specification is determined according to project requirements.
| Thickness | Imperial | R-Value | NRC |
|---|---|---|---|
| 16 mm | 5⁄8″ | 2.2 | 0.55 |
| 25 mm | 1″ | 3.6 | 0.75 |
| 38 mm | 1½″ | 5.5 | 0.90 |
| 50 mm | 2″ | 7.2 | 0.95 |
| 64 mm | 2½″ | 9.2 | 1.00 |
| 76 mm | 3″ | 10.8 | 1.00 |
Material performance at the stated thickness. Assembly performance (STC/Rw) depends on the full partition build-up — board type, layers, stud type and junction detailing. IFI can advise on WallSHIELD specification within the proposed partition build-up.
