Expanded recycled glass granules

Expanded Glass Granulate is produced of recycled glass applying a patented technique.Treated breakage of glass is fine-ground, mixed and formed. The granulate is sintered and expanded at a temperature of 750°C to 900°C in a rotary kiln. An ecological product made of mineral raw materials is produced this way.

Sound Absorption

Sound absorption or noise deadening, is one of the key properties of Quietstone. This is because the structure of the material is designed to take in and absorb the sound energy. This unwanted sound is then lost or transmitted away thus ‘deadening’ the noise.

Fire Proofing

Fireproof is one of the key properties of Quietstone. Fire protection is a valuable property required in a range of applications, from tunnel linings to marine engine rooms.
