Rockwool RWA45 insulation slabs

RWA45 insulation slabs from ROCKWOOL are versatile insulation slabs that can be used for both thermal and acoustic insulation in a range of general building applications. 

RWA45 characteristics

Rockwool RWA45 slabs are manufactured from mineral wool, which involves the heating of rock materials at high temperatures, before spinning it into hundreds of fine strands. These fine strands of fibre are then compressed and compacted into slab-shaped panels, bonded with resin. This manufacturing process means that the RWA45 insulation slabs are sturdy enough to retain their structure throughout the lifetime of the building, retaining a high thermal and acoustic performance, whilst also being easy to handle, manipulate and install. It also means that RWA45 slabs do not require any maintenance once installed. 

RWA45 acoustic insulation

ROCKWOOL RWA45 slabs are effective acoustic insulation products because they work to reduce noise in two ways. Firstly, they prevent the transmission of sound by acting as a barrier, and secondly, the sound is absorbed by the fibres within the RWA45 insulation, which are effective sound absorbers.

RWA45 fire resistance

All Rockwool RWA45 slabs are fire-resistant, achieving a Euroclass A1 non-combustible rating. This is the highest level of fire performance and means that RWA45 insulation can be used to compartmentalise rooms within a building, reducing the risk of fire spreading. 

RWA45 water repellent

RWA45 ROCKWOOL insulation contains water repellent qualities, which helps to prevent a build-up of moisture and damp, which can often result in rot, causing structural damage.

Rockwool RWA45 insulation slabs are available in a wide range of thicknesses, from 25mm up to 100mm, making them suitable for a wide range of applications, including ceilings, walls and floors.
