## Overview

Rockwool RWA45 acoustic insulation slabs offer professional-grade sound absorption and transmission reduction in three thicknesses (50mm, 75mm, 100mm).

## Description

Rockwool RWA45 50mm 75mm 100mm ACOUSTIC SOUND INSULATION Dimensions (Per pack) RWA45 50mm – 600mm x 1200mm = 9 slabs (6.48m2) RWA45 75mm – 600mm x 1200mm = 6 slabs (4.32m2) RWA45 100mm – 600mm x 1200mm = 4 slabs (2.88m2) Rockwool RW semi-rigid and rigid slabs are high quality resin bonded slabs that can be used for thermal and acoustic insulation in general building applications. The slabs are available in a wide range of thicknesses and densities to suit most requirements and are CE marked to EN 13162 Rockwool stone wool products work in two distinct ways to reduce noise, either by impeding the transmission of sound through an element of the structure or by absorption of sound at the surface. Noise absorption is expressed as a factor between 0 and 1.0. The more sound that a surface absorbs, the higher its absorption coefficient.
