acoustic underlay, noise control, sound absorber

AngelStep® 484P acoustic underlay is specifically designed for spaces with timber floors, offering an exceptional reduction of both airborne and impact noise above or below the floor. This underlay is of particular importance to the New Zealand Building industry as timber substrates dominate residential building.

AngelStep® GOLD8 acoustic underlay is designed to enhance the acoustic performance of all flooring. It is ideal for use in apartments, townhouses, upmarket housing, professional offices or wherever separating floors or adjoining dwellings are present, regardless of their flooring type.

AngelStep® acoustic underlays offer high performance sound-absorbing solutions designed to minimise the transmission of impact noise between inter-tenancy floors.

By providing a resilient layer underfoot, these solutions absorb and dampen impact vibrations and other noises, ensuring a quieter and more comfortable living or working environment in residential, commercial and a variety of other spaces.

Angelstep provides maximum performance for minimum thickness combining an impact and vibration damping and sound absorber with a decoupled noise barrier.

The resilient polyester 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 New Zealand and Australia in respect to separating floors between adjoining dwellings.

When AngelStep is installed, it delivers optimum performance and comfort for both resident and neighbours alike.

AngelStep® 484P Premium Acoustic Underlay for Wooden Substrates

Angelstep 484P is a 10mm thick laminate of double needle punched high density sound absorbent polyester and two layers of visco-elastic noise and vapour barrier.

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).

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

Acoustica’s product range of noise control solutions for flooring systems has been repeatedly independently tested to consistently achieve 5 and 6 stars in the Association of Australian Acoustical Consultants (AAAC) star rating system. However, results will vary depending on the construction, substrate and surface materials of each project.

Untreated timber joist flooring systems that separate individual tenancies exhibit very poor impact isolation performance.

AngelStep® 484P resets the bar for the acoustic performance of flooring underlay.

Field tests have achieved the ultimate 6 Star rating – streets ahead of the NZBC minimum standards.

Based on field test results 484P is able to achieve a IIC rating as high as IIC 65 to 70 which far exceeds the standard IIC 55 required by the NZBC G6 code of compliance

The installation of the AngelStep® 484P underlay has resulted in a significant improvement in impact isolation between tenancies (an improvement of ≈ 17 to 19 dBA).

Measurements and assessments of sound transmission through floor/ceiling systems are carried out in accordance with the following standards: AS ISO 717.2-2004: Acoustics - Rating of sound insulation in building elements. AS/NZS ISO 140.7-2006: Acoustics - Rating of sound insulation in buildings and of building elements.

AngelStep® GOLD8 Premium Acoustic Underlay for all substrate types

AngelStep® GOLD8 is a 8mm thick laminate of double needle punched high density sound absorbent polyester and a resilient ‘cross linked’ microcellular foam providing maximum performance with minimum thickness.

Its construction combines a highly effective support and cushion. It provides maximum performance for minimum thickness combining an impact and vibration dampener and sound absorber.

This noise barrier greatly reduces airborne sound waves - noise above or below the floor - and complies with the BCA and NZBC in respect to separating floors between adjoining dwellings.
