ISOLGRAEN is designed to give the roofs and wooden roofs in particular, an adequate increase of the sound insulating power, thanks to its sound-absorbing and sound-impeding performances. The rubber very high mechanical resistance makes the laying operations secure even in the most critical use conditions.
Wooden roofs acoustic insulation, directly laid on the timberframe and underneath the thermal insulation layer. Inserted in a double wall cavity to increase the sound insulating power.
