50mm Rockwool RWA45 Acoustic Sound Insulation Slab (6.48m2/Pack)

What Is RWA45 50mm? 

50mm Rockwool RWA45 Acoustic Insulation is a multi-application thermal, acoustic and fire insulation slab. 

Made from robust mineral wool insulation, it is purposed to minimise the noise in your home, as well as a wide variety of general building projects - from residential extensions to refurbishment builds. 

With a density of 45kg/m3, these acoustic insulation slabs do an incredible job of soundproofing, making them especially ideal for use in separating floors and internal walls. 

What's more, these high-quality resin bonded slabs are cut to 1200mm x 600mm, which allows them to slot perfectly between standard stud partitions and floor joists that are at 600mm centres. 

50mm Rockwool RWA45 slab is rated as A1 non-combustible in accordance with BS EN 13501-1, achieving the highest possible level of fire resistance and reducing fire spread within your project.

RWA45 50mm Storage & Handling

RWA45 50mm is a durable insulation solution which is hassle-free when it comes to cutting so you can get the best fit possible in all situations.

With a soft, fibrous texture, slicing through is effortless with a serrated blade. For optimal preservation, store the slabs indoors to maintain dryness.

RWA45 50mm Acoustic Performance

Rockwool thermal and acoustic insulation slab is best known for its excellent acoustic performance. 

RWA45 50mm slabs work in two distinct ways to dampen sound, either by impeding the transmission of sound through an element of the structure or by absorption of sound at the surface.

Its higher density and non-directional fibre orientation trap sound waves and deaden sound vibrations like no other insulation on the market. The open-porous structure of the fibres in RWA45 slabs grants them their incredible sound-absorbing performance, with characteristically high coefficients over a wide frequency range.
