Acoustituff is a tough, lightweight flexible vapour barrier consisting of polyester film bonded to aluminium foil with fire retardant hot melt adhesive and reinforcing scrim. The brown polyester film side is the side laminated to insulation while the aluminium foil side faces the airstream .
Acoustituff is used as a facing for Glasswool and Rockwool thermal and acoustic insulation. It provides a vapour barrier protection and protects the insulation from air erosion. The sealed, non-perforated surface offers an alternative to perforated foil and perforated foil-melinex film alternatives while still providing excellent sound absorption performance. Acoustituff is a cleanable surface and has excellent early fire hazard performance and complies with the requirements of AS1668.
