Acoustic underlay with super low heat resistance

Heat-Foil® has been designed especially for application over floor heating and floor cooling systems. Because of a minimal thickness of just 1,2 mm and a density of 150 kg/ m³, Heat-Foil® will simply transmit the warmth to the floor surface (TOG 0,14). Heat-Foil® is made out of a Polyethylene foil (200 micron) with a self adhesive overlap, combined with a most stable Polyethylene layer of foam.

Heat-Foil® is used in combination with click laminate and engineered wood flooring. When used over floor cooling systems a guarding systems against the transmission of water vapour needs to be present.

Heat-Foil® combined with Heat-Pak® is the most ideal choice over floor heating and floor cooling for glue down of ALL resilient finished floor coverings, such as sheet vinyl, lino, cork, rubber, LVT and carpet.

Combined with click laminate or engineered wood flooring Heat-Foil® shows an impact sound reduction of 21 dB ΔLw, measured according to EN-ISO 10140-3: 2010.
