Description
High Performance Thickset Endura 90 consists of 4″ hollow blocks with thicker faces. This extends the fire rating to 90 minutes when used as window assemblies within fire-rated walls. Increasing the face thickness allows for higher levels of safety, security, and reduced sound transmission, which is used in buildings designed for public use; hotels, schools, nursing homes, restaurants, and cinemas, etc., and in buildings where flammable or combustible materials are stored and/or handled.
Endura pattern’s narrow flutes provide moderate light transmission and maximum privacy.
Actual size of each block 7 3/4″ x 7 3/4″ x 3 7/8″.
With large projects that demand both resilience and fire protection, GBA delivers complete 90-minute fire-rated glass block systems with expert installation
