AngelStep® 48P acoustic underlay

AngelStep 48P acoustic underlay is designed for installation over concrete slab or light timber joists.

Suitable for carpet tiles, solid and engineered timber floors and timber laminates, AngelStep® 48P is 8mm thick and features a highly-effective ‘floating’ sound barrier above a noise absorbing core.

Durable and long-lasting, AngelStep® 48P won’t degrade under heavy weight and is also water and chemical resistant.

AngelStep® 48P achieves this with its unique and patented polymer construction. No degradation of acoustic properties due to structural collapse under the weight of heavy furniture, castors and appliances.

AngelStep®  48P is designed for a maximum traffic load of 65KN/m2 (approx. 6,500kg/m2)

AngelStep® 48P has been developed to suit construction over a concrete slab. It is supplied in tiles 1150x1150mm (1.3225m2)

The product has been independently tested to achieveLnt,w of 40 - equivalent to AAAC rating 6 stars tested by Marshall Day Acoustics; document 002 2007125 10/12/2015. The base floor/ ceiling construction, as shown in diagram 1, is considered to be representative of the performance of a typical masonry floor system that could be installed in an apartment that is required to achieve compliance with the impact sound insulation ratings detailed in the 2007 version of the Building Code of Australia; ie, Ln,w+C1 ≤ 62. A timber or tiling floor installed with Angel Step® 48P achieves an Ln,w 40 - 6 star performance with a floor/ceiling construction as per figure.
