Envirograf TCB Thermal Cavity Barriers are an ideal solution to window and door apertures, particularly in timber-framed buildings, providing thermal protection in the cavity and fire protection for up to an hour. Creating an effective thermal barrier between cavities and window/door frames, thermal cavity barriers are completely waterproof and moisture resistant.
The 30mm-thick fireproof sponge is fixed to a thin foil-clad strip of intumescent material that expands in a fire to seal gaps, preventing the spread of smoke and fire. This can give more time for evacuation in an emergency, and helps contain a fire to prevent more damage.
The cavity barriers are available in 1m and 2m lengths and at different widths, depending on the cavity size.
Examples of Use
With rising energy costs, it is now vital to ensure homes and businesses are properly insulated to reduce escaping heat energy, keeping spaces warmer for longer. Gaps and reveals in door and window frames can lead to significant heat loss as well as damp issues, resulting in lengthy and costly repairs in the future.
Simply cut to the length required and fix using clout nails at 6 inch (150mm) centres.
