Angel Step® acoustic underlay from Acoustica - the treatment of impact and airborne noise transfer through floors
Angel Step® is an acoustic underlay for carpet and solid
timber or laminate floating floors. Angel Step'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.
Angel Step® 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.
Angel Step® is moisture resistant. Exposure to an atmosphere of 50%
and 95% relative humidity for four days showed that Angel Step® has
a moisture absorption rate of less than 2% by volume.
