Poraver® expanded glass is a versatile lightweight aggregate for high-quality building materials and industrial products. PORAVER® offers a mix of outstanding characteristics which no other product in this spectrum has. Despite its low density, Poraver® is very resistant to pressure. It not only acts as thermal insulation but also absorbs sound, dimensionally stable over the long term, and resistant to fire, moisture and chemicals. Poraver® consists of recycled glass and is 100 % mineral.
In 1983, Poraver® was the first expanded glass granule made of post-consumer recycled glass on the market. The development of the manufacturing method was the basis of the success story which is still going on today. Since then, we have been manufacturing lightweight aggregates at our production sites in Germany and Canada for customers and distributors throughout the world. We are the largest expanded glass granule manufacturer and market leader worldwide.
