Viterolite 300

sustainable non-fibrous sound absorbing tiles

Viterolite® 300 – The versatile sound absorber for challenging environments. Viterolite® was developed to meet requirements of a durable, sustainable sound absorber that is non-fibrous and overcomes issues of weather aging and contamination damage.

Viterolite® 300 are pre-cast tiles made from expanded glass granules that are produced from recycled glass. The processed granules are bonded together using a polymer resin binder. Each granule inherently acts as an acoustic absorber and the polymer resin binder considerably enhances the impact resistance of the tiles.

The result is a light-weight, porous, sound-absorbing panel with excellent impact resistance properties that are suitable for both external and indoor use. They are an ideal choice for areas with challenging weather and impact conditions such as train stations, as well as indoor areas with high humidity or fire concerns. Unlike traditional porous or open-cell materials, its natural resistance to moisture ensures that the panels will not significantly retain or absorb moisture. Viterolite® achieves the highest fire rating -‘Class O’ required by British building standards.

Viterolite® 300 tiles can be worked on site and retrofitted to reflective surfaces such as concrete walls to provide effective noise absorption. The panels can withstand weather conditions, impact, animal infestation and have a long life-span without any additional treatment.

They can be cut into different shapes and sizes, routed to provide varying texture and shadowing effects, thereby opening up several aesthetic options for interiors as well as outdoor applications. Constructed from recycled material, and VOC free, Viterolite® tiles are easy to work on, fix and maintain.
