Envoy Silver

Envoy Silver is a closed cell, non cross linked polyethylene foam with a silver metalised damp proof membrane. This film has excellent barrier properties that can be compared with a heavy duty LDPE film and thus avoiding humidity coming from the concrete.

Installation

To install Envoy Silver, simply roll out the underlay across the floor, place the next widthagainst the previous one (do not overlap), join the seams with adhesive tape. For a fast and easy installation Envoy silver is also available with an integrated tape onthe overhang or on the roll.
