min
Use:
Envirograf® intumescent fire and smoke seals are fitted
into rebates in doors and/or frames. The release paper on
the adhesive backing is removed and then the strip is pressed
into the rebate in the door or frame and secured at each end
with pins. Once fitted, the plastic facing can be painted,
although the brush and rubber seals themselves must not be
painted over. Sizes available 10x4, 15x4, 20x4, different
colours and different types of smoke seals available.

Intumescent Air Transfer Grilles
Use:
Envirograf® Metal Grilles type MG (slotted) and type MGL
(louvred) are utilised either side of a ventilation opening
in doors and walls, and they are sold as a set of two grilles.
Matching individual plain metal grille plates are available
for use in non-risk situations. The sets are defined in two
ways: the /D version is for use in situations in which the
risk is double-sided (that is, the opening could be attacked
by fire from either side); and the /S version is for use in
situations in which it has been clearly identified that only
a single side of the opening is at risk. When fitting the
/S version, the intumesced plate is placed on the risk side
and the plain plate is placed on the opposite side of the
opening. Sizes available upto 550mmx550mm

can be individually adjusted to allow for warped doors. CE

Intumescent Glasing Tape
Use:
Envirograf® intumescent glazing strips are used in timber
and steel doors and in partitioning, where the strips are
fitted to beads either side of the glazing. Although the seal
is only 2mm thick, it can also be compressed down to 0.5mm
with no detriment to its intumescent performance.
