AESTUVER fire protection board

Aestuver are lightweight, cement-bonded, glass-fibre-reinforced concrete panels for high-quality fire protection.

– Fire protection solutions for walls / ceilings, beam / column cladding, electrical and ventilation services, and special constructions

– Weather-resistant, frost-resistant and water-resistant

– Fire protection solution for environments placing high climatic demands on components

– The sanded surface of the material provides a good bond with adhesives and other finishes
