Glass Fire Door Seals


Glass fire doors present particular desgn challenges because unlike glazed fire doors there is often no substantial frame to restrain the glass so that it delivers the required fire resistance performance.  Sealmaster intumescent seals have helped glass fire door designers overcome these challenges.

Glass fire doors allow the optimul flow of natural light whilst achieving 30 or 60 minutes fire resistance performance.
