Viterolite 900

Viterolite 900

non-combustible sound absorber

Viterolite® 900 is a non-combustible sound absorber ideally suited for areas which require no smoke emission, volatiles, toxic or noxious gases such as tunnels, air shafts or public areas. It is constructed using cement binding agents, ideally used in high wear, high impact and trafficable areas.

It can be custom made into any shape or size. Typical custom applications include wall panels, road barriers, air shaft linings, rail and vehicle tunnels.

Viterolite® 900 has been engineered to optimize maximum sound absorption across a broad frequency range while maintaining a natural concrete-like appearance.
