Bandages are made using Firefly 101 or 102 intumescent and are
enclosed in aluminium foil. Fireplug FPBs are designed to
fit into solid walls and floors directly around the service penetration.
This does away with the need for a potentially expensive
and clumsy metal canister. The solid structure inside which
the Fireplug bandages sit act as a wall of a canister, thus ensuring
the Intumescent is kept where it is needed.
content in an FPB will fill a larger hole when activated however
allowance has not been made for the frogs in bricks etc.
In these circumstances we recommend making good with sand and
cement, plaster or similar gap filler. A rough rule of thumb
would be if after fitting the bandage there is a gap of more than
10mm between the Fireplug FPB and the wall/floor it should be
made good. Fireplug FPB Bandages are normally supplied in
one length. Larger sizes may be supplied in more than one
length for ease of fitting.
Under the action
of heat PVC. pipe softens as the intumescent strip expands sealing
the hole through the wall or floor. In the instance of metal
pipes the intumescent absorbs the heat and detracts from it tracking
along the pipe and thus breaching the fire break structure.
Copper pipe can also melt or collapse in this case the intumescent
will act as with PVC. pipe. Lagged pipes should also be
protected as the intumescent will crush the insulation as it burns
has been tested by TRADA to British Standard BS476 part 20, on
14th May 1993, test No. IT360 and at the Building Test Centre
to British Standard BS476: Part 22: 1987: clauses 5, following
the methodology of PREN 1366.3 (1993) where 150 minutes insulation
and integrity was achieved. Full test reports are available
Bandages are wrapped around the pipe/service and secured tightly
to itself using the adhesive tongue. If there is more than
one piece to the bandage each will carry an adhesive tongue.
After attaching to the pipe the Fireplug FPB can be slipped along
and into the wall/floor. Note the possible need for making
good with mortar.
