High Performance

High Performance products consist of 4” glass block with thicker faces and solid glass block. This allows the glass block to extend its standard 45 minute fire rating to include 60 and 90 minute when used as window assemblies within fire-rated walls. The increased face thickness combined with solid glass bricks, allows for higher levels of safety, security, reduced sound transmission, and in some cases, ballistic capabilities.
