AngelStep® GOLD4

acoustic underlay for ceramic and carpet tiles

AngelStep GOLD4 acoustic underlay is primarily designed for ceramic and carpet tiles, but can also be used with solid timber, engineered timber floors, vinyl ‘klip’ planks and underfloor heating systems.

Moisture and rot resistant, AngelStep® GOLD4 features a gold aluminium facing foil combined with a high-density sound absorber for superior sound and impact noise reduction. Use foil side up for solid or engineered timber, or use foil side down resulting in a vapour barrier with ceramic tiles.

Boasting all the patented technology and high acoustic performance of the AngelStep® range, AngelStep® GOLD4 is just 4mm thick and can be layered for best results.
