Envoy Gold is a closed cell, non cross linked polyethylene foam with a golden damp proof membrane. Envoy Gold, based on corrugated foam, has been developed especially to reduce a maximum of transmission sound and is best suited in combination with laminate floors when installed in apartments and new buildings.
