PYROSTRIP 100EC or 500 intumescent seals are nominally 2mm thick and are produced to the necessary width to suit the required fire performance.

PYROSTRIP 100 EC is white in colour, and PYROSTRIP 500 is charcoal grey.

It is recommended that the width of the PYROSTRIP should be set between

7 to 10mm in from either face of the door leaf. The timber lipping should be between 6 to 8mm. For FD30 doors, it is possible to have PYROSTRIP

concealed along the vertical edges and across the head of the door.

For FD60 doors, PYROSTRIP can be concealed along the vertical edges, but the head of the door/frame must have an exposed PVC encapsulated version. As a general rule the width of PYROSTRIP should be as follows: FD30 30mm x 2mm FD60 40mm x 2mm. The above is based on experience of successful fire tests conducted by numerous fire door manufacturers. Suitable adhesives must used for bonding the lippings. They should exhibit a thermoplastic nature under fire conditions, such as, 2 pack polyurethane,

hot melt adhesives or a suitably modified PVA adhesive. Suitably tested hinges must be used within the construction, to minimise the restriction of expansion of the PYROSTRIP in these areas.

PYROSTRIP 100EC and 500 has been successfully fire tested to BS476 parts 8 and 22, NEN 6069, by various door manufacturers.

Using Pyrostrip 100EC or 500 range of high performance intumescent seals, it is possible for fire door manufacturers to produce doors, with the intumescent concealed into the door lipping. This allows Architects the opportunity to specify high quality fire resisting doors, without exposed seals conflicting with the decorative finish.

PYROSTRIP 100EC and 500 can be inserted into the back of timber lippings on the hanging and swinging stiles of fire resisting doors. The lipping should be grooved slightly bigger than the seal to allow for shrinkage of the timber.

In a fire situation, the adhesive bonding of the lipping softens. As the temperature of the intumescent reaches approximately 100°c it begins to expand pushing off the lipping, wedging it against the door frame. This seals the gap and prevents the passage of smoke, hot gases and flames.
