Intumescent Fire and Smoke Seals
Envirograf® Product 100 is available in two styles: original and new push-fit. Both styles of
fire and smoke seals consist of a plastic holder containing an intumescent fire seal and either
brush or rubber smoke seals. The original style is also available as a plastic holder fitted with
an intumescent fire seal only, for use when a smoke seal is not required. However, as smoke
kills before flame, it is always advisable to fit intumescent seals with smoke seals. The original
style is supplied in 1050mm or 2100mm lengths, backed with self-adhesive tape for easy
fitting in rebates, whereas the new push-fit seals are supplied in 2100mm lengths only and
they simply push into place with no need for adhesive or other fixings, making them ideal as
replacement seals. The standard colours of the plastic holders are brown and white, but other
colours may be available (please check availability before specifying or placing an order).
U S E
Used for fitting to doors, door frames, and windows. Once fitted, the plastic facing of the seals
can be painted, although the brush or rubber smoke seal must NOT be painted.
