ETHAFOAM* is a closed cell foam sheet with very good
impact sound insulation properties which can be used as
a resilient de-coupling layer in concrete floor constructions.
Due to the low thickness ETHAFOAM is suitable for use in
projects with floor height limitations (e.g. refurbishment).
Its low moisture sensitivity makes it an excellent product
for use in humid environments, such as bath rooms.
