Hear the difference with 100mm Rockwool RWA45 Acoustic Insulation: a multi-application thermal, acoustic and fire insulation solution made from mineral wool, suitable for use in a wide variety of general building projects - from residential extensions to refurbishment builds. 100mm Rockwool RWA45 slab is rated as A1 non-combustible in accordance with BS EN 13501-1, achieving the highest possible level of fire resistance.
This acoustic insulation slab (often referred to as a Sound Slab - no prizes for guessing why), has a density of 45kg/m3, giving it excellent acoustic soundproof properties and making it ideal for use in separating floors and internal walls. 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.

Rockwool is recognised as being the market-leading acoustic insulation solution. All Rockwool RW slab products offer outstanding fire, acoustic and thermal insulation properties as well as lifelong durability. Rockwool RW semi-rigid slab products, either un-faced or with an aluminium foil or glass fleece on one or both surfaces, achieve an A1 classification in accordance with BS EN 13501-1 and thus meet the requirements of non-combustible materials, as defined in UK and Ireland Building Regulations.
The 100mm is the most popular thickness of the Rockwool RW slab range and has a pack quantity of 4 slabs (25mm, 50mm, 75mm, and 100mm) and a thermal conductivity of 0.035 W/mK.
RWA45 is a durable insulation solution which is trouble-free when it comes to cutting so you can get the best fit possible in all situations. The slabs have a soft, fibrous texture, very similar to a loaf of bread. Because of this, a serrated blade is all you need to slice through it.
When it comes to storage, we advise that you store the slabs inside; keeping them nice and dry.
A robust insulation solution, 100mm RWA45 Slabs are the most popular acoustic and soundproofing insulation product on the market. Although Rockwool offers excellent thermal performance with a thermal conductivity of 0.035 W/mK, Rockwool thermal and acoustic insulation is best known for its excellent acoustic performance.
In comparison to other insulation materials, Rockwool is highly effective at preventing noise transmission from room to room, making it ideal for installation in internal and separating walls. Its higher density and non-directional fibre structure trap sound waves and deaden sound vibrations like no other insulation on the market.

Great acoustic insulation slabs. Really reduced the sound from upstairs after my daughter moved back in. Next time I need any acoustic and thermal insulation, I'll be sure to come back to this site.
