In addition to providing insulation and acting as a substrate for roofing, in many situations roof insulations also need to provide noise reducing characteristics. Building constructions near airports or other high noise areas require noise reduction principles to be employed. 

Sound travels through a building component because it sets up vibrations in that component. Almost all building materials are sufficiently elastic to transmit sound. The result is sound transmission through the construction. In addition, numerous other factors must be considered in proper sound control design. Such factors include background noise level, and transmission through floors, walls and penetrations through the construction (which also includes insulation joints). 

With our acoustic solution range, we are pushing the technical limits of the materials used as thin acoustic underlayments. A compromise between acoustic and mechanical performance: ΔLw of 22 dB and mechanical performance a2. In double layer, the impact noise reaches 25 dB. In other words, excellent acoustic and mechanical results, and for a long time.
