AngelStep^® Acoustic Underlay

Treatment of Impact and Airborne Noise transfer through Floors

AngelStep^® is an acoustic underlay for carpet and solid timber or laminate floating floors. AngelStep’s construction combines a highly effective support and cushion for floating floors. It provides maximum performance for minimum thickness combining an impact and vibration damping and sound absorber with a decoupled noise barrier.

AngelStep^® comprises an 8 mm layer of double needle punched polyester matting sandwiched between 4 kg/m² ‘visco-elastic’ polymer flexible noise barriers.

When laid over timber floors the first barrier in contact with the floor seals and damps the flooring substrate (T&G, ply, chipboard, marine ply). For concrete floors Angel Step® can be ordered without the bottom noise barrier.

The resilient polyester middle core layer absorbs impact energy and residual airborne noise from above and below, transforming wave vibrations into heat energy.

The ‘decoupled flexible floating’ top noise barrier greatly reduces airborne sound waves - noise above or below the floor - and complies with the Building Code of Australia in respect to separating floors between adjoining dwellings.
