Rockwool RWA45 Acoustic Insulation Slab: a robust 3-in-1 thermal, acoustic and fire insulant. 

This multi-application mineral wool insulation solution is suitable for a host of general building projects and specialist specifications- from residential extensions to refurbishment builds in both commercial and leisure applications. 

Thanks to its non-directional fibre structure and 45kg/m3 density, 100mm RWA45 is second to none when it comes to acoustic performance, making it the ideal solution for use in separating floors and internal walls. 

In terms of its fire performance, 100mm Rockwool RWA45 slab remains unbeatable, achieving an A1 non-combustible rating - the highest possible level of fire resistance. Rockwool RWA45 100mm can be used as a means of reducing fire spread and damage. 

Users of RWA45 can rest assured that these premium-quality semi-rigid slabs are not only optimising the fire protection of their build but (with a thermal conductivity of 0.035 W/mK) are also working in tandem to protect its thermal envelope.

Rockwool Sound Insulation Slab Applications

Unrivalled in its acoustic performance, 100m RWA45 (often referred to as a Sound Slab - no prizes for guessing why), makes for the ideal solution when soundproofing separating floors and internal walls. Not only will it maintain the volume within your project, but it will also protect it with an immaculate A1 non-combustible rating. 

To make life easier, Rockwool slabs are resin bonded and cut to 1200mm x 600mm, which allows them to slot perfectly between standard stud partitions and floor joists that are at 600mm centres.
