GB15 Intumescent Strips
When Georgian and other period buildings undergo refurbishment or a formal change of use, the level of fire safety protection must frequently be improved to meet modern fire safety standards. Unfortunately it is not possible to fire rate the small panes of glass fixed into thin glazing bars characteristic of the Georgian style because these are consumed so rapidly during a fire. Sealmaster GB15 intumescent strips avoid this problem, giving glazed doors or partitions a Georgian appearance – with a fire rating of 30 or 60 minutes. The glazing bars are fixed to each face of larger panes of Pyran S glass in a lattice framework. To prevent the heat radiated by a fire from igniting the beads on the unexposed side, the bars automatically detach in the first few minutes of a fire- forced away from the glass by the GB15 intumescent strips which swell under heat to produce the required pressure. The large pane then reverts to provide 30 or 60 minute protection (depending on the FireGlaze system used to protect it).
