FIREPLUG
INTUMESCENT STRIP
|
|
- For Rebating
|
Fireplug Intumescent
Strips are available white or brown, in standard 2100mm or 1050mm
lengths and is supplied self adhesive. Fireplug Intumescent
Strips are also available in door sets. Packed 5 x 1050mm
for single doors and 10 x 1050mm for double doors. |
Fireplug IFS104,
IF104, IFS204, IF204 are produced using Firefly 102 intumescent
material and encased in a PVC sleeve, achieving a high degree of
protection from mechanical and chemical damage. |
Fireplug Profile
ref IF - is in a cross section as shown above, rectangular,
normal sizes 10mm wide x 4mm deep (ref: IF104) for 1/2 hour protection,
20mm wide x 4mm deep (ref: IF204) for 1 hour protection. |
Fireplug Profile
ref IFS - differs from Fireplug IF where smoke inhibition is
required. In this instance a 5mm long brush pile incorporating
a polypropylene blade is inserted along the entire length of the
PVC profile. Ref IFS104 for 1/2 hour protection and ref IFS204
for 1 hour protection. |
Under the action
of heat, the PVC profile softens as the intumescent core expands
sealing the gap between the door and the door frame, through which
fire and toxic gas could pass. The amount of pressure developed
by the expanding intumescent is dependent on the gap to be
sealed. The wider the gap the lower the pressure.. The
temperature at which Fireplug Intumescent strip starts to activate
is 120 - 160 oC. At this temperature no one would survive on the
fireside of the door and in most cases the thermal shock would be
fatal to anyone on the unexposed side opening the door. However,
despite the requisite that the pressure developed by the expanding
intumescent is sufficient to keep the door closed it is possible
to make the door open if required. |
Fireplug IFS104
and IF104 has been tested by TRADA to British Standards BS476 Part
22, on April 20th 1993, test No. FR1687. The test criteria
attained in Fireplug Intumescent Strip being acceptable for use
in many leading manufacturers doors for 30/30 half hour doors, likewise
Fireplug IFS104 and IF104 has been tested for use on 60/60 one hour
doors. |
Fireplug IFS104
and IF104 is fitted into a groove nominally 10mm wide x 4mm deep.
To aid fixing, although not essential, the strip can have a self
adhesive backing, alternatives to this are gluing or securing with
tacks. IFS104 and IF104 are fixed similarly but the groove
is nominally 20mm wide x 4mm deep. The groove can be routed
into either the door or into the door frame. The rout is along
the head of the door and down the jamb. Intumescent is not
required along the bottom as in a fire situation a negative pressure
results making the air flow in the opposite direction to the top.
Where the groove is masked by hinges,
locks or other door ironmongery we recommend that FIreplug Intumescent
Strip is used in conjunction with Fireplug Hinge and Lock Protection.
If a smoke seal is required then the Fireplug IFS Profile can be
used. The recommended gap around the door is 4mm, this enables
ease of opening and closing against the brush stroke seal. |
| N.B.
i) Never use brush seals
in both sides of meeting stiles. ii)
Always fit the IFS brush directly opposite the IF profile.

FIREPLUG INTUMESCENT
STRIP - SURFACE MOUNTED
|
|
| Fireplug
surface mount intumescent strip is available in most colours,
or with a real wood veneer. All seals are self adhesive.
These seals can be ordered made up into complete door sets.
A single door set consists of 3 lengths FP202 and 2 lengths
FP102. Ref: single door set FPSD A double door set consists
of 4 lengths FP202 and 4 lengths FP102. Ref: double
door set FPDD. |
|
The surface mounted
intumescent fire and smoke seals are 25mm wide incorporating 20mm
wide intumescent plus 5mm wide brush smoke seal, complete with polypropylene
blade. FP202 is nominally 2mm thick, FR102 is nominally 1mm
thick. FP102 is used for ease of fitting to the hinge jamb,
where you would expect a smaller gap in comparison to closing jamb
or head. All seals come self adhesive as standard. |
Under the action
of heat, the intumescent rapidly expands to seal around the door
stopping the passage of fire and toxic gases. The brush smoke
is designed to inhibit the passage of cold smoke. |
Fireplug FP202
and Fireplug FP102 have been tested by TRADA to British Standards
BS476, Part 22, on April 20th 1993, test No. FR1687. |
Fireplug Surface
Mounted Fire and Smoke Seal is supplied in door sets. The
thicker pieces, Fireplug FP202, are installed on the closing lock
jamb and the head of the door. The thin pieces, Fireplug FP102,
are installed on the hinge jamb, the surface mount strip is placed
over the metal of the hinge, this is to absorb the heat off the
metal and to prolong the efficiency of the hinge. A gap of
3 - 4mm is required to the head and closing jamb prior to application.
A single door set will fit any door up to 2100mm x 1050mm wide.
if necessary additional strips can be supplied using the refs: FP202
and FP102. |

that ironmongery should be protected using Fireplug Hinge Strip
and Lock Protection (ref Fireplug CFPM). |
