SURPASSING THE BUILDING CODE STANDARD

The Building Code of Australia (BCA) regulates the minimum acceptable construction standard for buildings and in Clause F5.4 (a) stipulates the weighted normalised impact sound pressure level Ln,w plus the spectrum adaption term Ci. The BCA minimum impact standard for a floor in a class 2 or 3 building is to be no more than Ln,w+C1 ≤ 62.

AngelStep® with an impact sound pressure level on a concrete substrate of no more than Ln,w+C1 of 40, exceeds the BCA requirements by 22 points.

Many apartment owners have become dissatisfied with the acoustic performance of buildings built to the BCA minimum impact standard of Ln,w+C1 ≤ 62, which some building industry members have interpreted as absolute rather than minimum requirements. To address the concerns of the community and industry the AAAC introduced a star rating system to promote better standards of acoustic quality.

AngelStep® acoustic underlay carries the maximum AAAC 6 Star rating compared to the low-end rating of 21/2 for the BCA, Ln,w+C1 ≤ 62 minimum acceptable standard, a level of amenity which any owners, occupiers and developers will find unacceptable.

SCORES

CONSTRUCTION

AngelStep® provides highly effective support and cushion for timber, laminate and tiling flooring, is unaffected by water and will last the lifetime of the building.

AngelStep® consists of an 8 mm thick impact, noise and vibration damping absorber made from 75% recycled materials combined with a decoupled ‘visco-elastic’ noise barrier.

AngelStep® 48P with one noise barrier is used over a concrete substrate. AngelStep® 484P with the absorber sandwiched between layers of 2mm thick noise and vapour barriers is for use over a timber substrate.
