angelstep® gold 4



The AngelStep® GOLD 4 Acoustic Underlay is designed primarily for ceramic and carpet tiles, but can also be used on solid wood, engineered wood floors, vinyl "clip" planks, and underfloor heating systems.

Resistant to moisture and rot, the AngelStep® GOLD 4 combines a gold-coloured aluminum topsheet with highdensity sound absorbing materials for superior sound and impact noise isolation. Use foil side up on solid or treated wood and foil side down to create a vapor barrier on ceramic tiles.
