Envoy Sonic
Envoy Sonic is a high-tech underlay with superior density and weight, especially designed for heavy duty applications where acoustic insulation and heavy surface loads are needed. Envoy Sonic offers an acoustic insulation and reduces the sound level in the underlying room as well as the click-clack sounds of floating floors in the room itself.
Envoy Sonic attacks impact and air borne sounds in one single product, making it a unique, high performance acoustical underlay. The underlay is based on a synthetic rubber with a membrane of cross linked polyethylene high density foam. As a result Envoy Sonic is a durable, long lasting underlay with an excellent resistance to compression.
