Regupol 3912 is specially designed and manufactured for use in timber-based constructions in timber floors. The timber acoustic underlay utilizes PUR foam to reduce impact sound by up to 50dB. PUR foam is a high-performance material that's still easy to cut and very flexible. This makes installing this product easy, with rolls 6mm thick available for a range of different sized jobs. Once Regupol 3912 acoustic underlay has been laid, simply seal with acoustic sealant to complete the acoustic insulation layer. Compatible for installation in timber constructions and refurbishment projects, as marked out in Part E Building Regulations, this tough underlay from Regupol will continue to perform even if it's under heavy loads. What's more, it can be installed above or below underfloor heating and it's compatible with all floor finishes. Regupol 3912 will reduce impact sound significantly for timber joisted floors, ideal for installing on upper floors in domestic residences, in apartment blocks to reduce noise between tenants, and in commercial offices or schools.
