Acoustic Flooring Underlay: AngelStep® 630



Part of the high performance AngelStep® range, AngelStep® 630 acoustic underlay is designed to enhance the acoustic performance of vinyl flooring. At just 4mm thick, it is highly effective against impact and airborne noise, as well as vibration damping.

It has a resilient polyester structure that absorbs impact energy and airborne noise from above and below.

AngelStep® 630 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.

Despite its thin profile, AngelStep® 630 will not degrade in acoustic performance under heavy weight of furniture or appliances. Acoustica Projects will advise if any additional support is needed such as flooring grade plywood, if vinyl is thin or does not interlock or clip together.

The BCA provides minimum construction standards for various building classes including acoustic privacy.

The BCA requirement is a weighted standardised impact sound pressure level with spectrum adaptation term Ci, of less than or equal to 62 Lnt,w+Ci. However, the reality is that this is in most cases unacceptable to occupants and can result in the need for costly reparation works. In response the Association of Australian Acoustic Consultants (AAAC) has developed the star rating system to rank the acoustical quality of apartments and provide guidance in the design and construction process.
