Raise the acoustic rating of any wall, ceiling or floor.
AcoustiLayer® mass loaded vinyl is the concealed barrier that lifts the performance of standard building assemblies - party walls, partitions, suspended ceilings and timber floors.
Why mass loaded vinyl in buildings
A standard stud wall is light, so airborne noise passes straight through it. The fix is mass and decoupling. AcoustiLayer® adds a dense, limp barrier inside the build-up that reflects sound back - raising the assembly's rating without rebuilding the wall or losing significant floor space.
At 2-4 mm it slips behind plasterboard, into ceiling voids and under floating floors, and its water-resistant vinyl suits damp areas such as plant rooms and basements.
Where to apply it
- Party & partition walls - between flats, hotel rooms, offices and studios.
- Ceilings - over or under suspended grids to stop floor-to-floor noise.
- Timber floors - under battens or screed as part of a floating floor.
- Risers & service voids - wrap noisy pipework and ducts.
- Plant & generator rooms - line walls to contain equipment noise.
A typical wall build-up
From the noisy side inward: plasterboard → AcoustiLayer® MLV → mineral wool in the cavity → plasterboard, ideally on resilient bars so the leaves are decoupled. Seal perimeters with acoustic sealant - flanking paths and gaps undo the mass you've added.
Mass law means roughly every doubling of mass adds about 5-6 dB. Combining MLV with decoupling and an absorbent cavity gives far more than mass alone.
Which thickness to choose
Use 2 mm for ceilings and lighter partitions, 3 mm as the standard choice for party and partition walls, and 4 mm where the target rating is high or space for extra layers is limited. Every grade is the same 2000 kg/m³ AcoustiLayer® vinyl.
