Hear the difference with 100mm 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.
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.
The slabs can be used in multiple applications, including the following:
- Interior timber or steel partition walls
- Interior timber frame floors
- Interior timber frame ceilings
- Acoustic ceilings and partition panels
- I-joist interior partitions
- Pitched roofs
- Party walls
- Industrial applications

Rockwool 100mm RWA45 Certifications
BS EN is British and European Standard Specifications. With over 100 years of experience, the British Standards Institute is recognised as the UK’s National standards body. BS EN considers Rockwool both:
- A1 non-combustible in accordance with BS EN 13501-1 - achieving the highest possible level of fire performance/resists high temperatures
- CE and Key marked in accordance with BS EN 13162:2012 + A1:2015.v
100mm Rockwool slabs are also certified by Lloyd's register of shipping as non-combustible materials for use on:

Rockwool RWA45 Insulation Storage & Handling
RWA45 slabs boast a soft, fibrous texture, very similar to a loaf of bread. Due to this soft composition, a simple serrated blade is all you will need to slice through them.
When it comes to storage, we advise that you store the slabs inside, protected from the elements.
100mm RWA45 Acoustic Performance
With a density of 45kg/m3, Rockwool thermal and acoustic insulation quells unwanted noise like no other. The non-directional fibre structure of the mineral wool essentially traps sound and keeps it locked in so it will not travel to the other side.
It is this absorbent nature which renders 100mm RWA45 Slabs the most popular acoustic and soundproofing insulation product on the market. In comparison to other insulation materials, Rockwool offers excellent acoustic performance and is highly effective at preventing noise transmission from room to room as well as deadening sound vibrations.
Due to the fact that noise tends to bleed most through internal and separating walls, RWA45 is best suited within these applications to keep noise levels to a comfort-friendly decibel.
The RW Slab product range consists of a variety of thicknesses and densities.

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) as well as a thermal conductivity of 0.035 W/mK.
Fantastic product. When it came to adding these in between the studwork, they were simple to fit into place and then to cut I used a bread knife, as I didn't have a drywall knife - the slabs are like you are cutting bread! The RWA45 slabs have helped reduce noise between rooms since I've installed and I would recommend buying them.
