GENERAL INFORMATION

Insulating glass blocks are manufactured by heat fusion at more than 800°C of two hollow half bricks obtained by compression of a glass drop* at about 1050°C. - Fusion is obtained at approximately 1550°C. The blocks are annealed at 560°C to eliminate internal tensions and contain rarefied air. The *glass composition is: Silica-sand, soda ash, and calcium.
