Envoy Basic is a closed cell, non cross linked polyethylene foam, the low cost alternative quality performance underlay for all floor types. It is ideally suited for a floating installation of laminate and wooden parquet floors and levels out slight unevenness in the subfloor.


For a fast installation simply roll out the underlay across the floor and make sure that the joins are butted tightly together; the joins should be sealed with an adhesive tape. A damp proof membrane can be used in conjunction with Envoy Basic to ensure extra protection against humidity.
