DESCRIPTION
THERM-A-CHANNEL is a specially compounded intumescent elastomeric material which is extruded into a 12 mm x 15mm channel, forming a glazing gasket which cups the edge of the glass pane. Being elastomeric the gasket is impervious to water and atmospheric moisture.
PERFORMANCE
THERM-A-CHANNEL has been designed and tested for use in the 30 minute glazing applications found in screens and firedoors, using either wired or clear fire rated glass. It is approved for use with glass sized up to 700 x 800mm in FD30 and FD30S fire doors and screens. As with any fire-rated element it is essential that the construction used is of a type previously tested, and therefore the following specifications should be
followed: |
