AngelStep® 630 acoustic underlay for vinyl

The AngelStep® range is an acoustic underlay for the treatment of Impact and airborne noise transfer.


AngelStep® construction combines a highly effective support and cushion. It provides maximum performance for minimum thickness combining impact and vibration damping and sound absorber.


The resilient polyester core layer absorbs impact energy and residual airborne noise from above and below, transforming wave vibrations into heat energy. 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. When AngelStep® is installed, it delivers optimum performance and comfort for both resident and neighbours alike


Compared to products made by others, Acoustica’s AngelStep range of underlays have been shown in independent comparison tests to offer a more effective acoustic treatment, a thinner solution, that is also cost effective.


The product has been independently tested:


to achieve Lnt,w of 37 - better than AAAC rating 6 stars - independently tested by Vipac Engineers & Scientists Ltd May 2016; document 20E-16-0040-455704 under loose lay vinyl in a building over 50 years old

to achieve Lnt,W of 43 - better than AAAC rating 5 stars - independently tested by Vipac Engineers & Scientists Ltd October 2016; document 20E-16-0192-ADM-456564-0 under Novocore vinyl with a 200mm concrete slab with bare concrete ceiling

It is 4mm thin and is supplied in tiles 1200x1200mm(1.44m2)


The unrivalled performance of AngelStep® 630 is due to its unique and patented polymer construction. No degradation of acoustic properties due to structural collapse under the weight of heavy furniture, castors and appliances. For thin vinyl or vinyl that does not interlock or clip together we recommend installation of the vinyl on top of flooring grade plywood on top of the AngelStep product.
