Envoy Ultra
Envoy Ultra is a cross-linked closed cell polyethylene foam underlay, especially designed and developed for use under all laminate and solid wooden floors. It combines thermal and sound insulation with damp proof performance. Envoy Ultra has excellent drum sound and impact sound properties. Its outstanding compressive creep performance makes it suitable for use in residential homes.
