Noise absorption is expressed as a factor between 0 and 1.0. The more sound that a surface absorbs, the higher its absorption coefficient. ## Features - 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.
