POLYFLAME is a range of modified bitumen membranes with a reinforcement of high quality non woven, polyester which provides suppleness and flexibility to compliment the plastomeric qualities of the bitumen blend at both high and low temperatures. The inlay is positioned within a matrix of bitumen modified with a special blend of polypropylene thermoplastic polymers ((APP) The polyester fabric is rot proof and extremely robust with certain isotropic qualities. Other weights of polyester are available on request.


POLYFLAME a general purpose membrane,  excellent in single layer roofing systems used with GLASFLAME as part of 2 or 3 layer systems in underground structures, multi-story car parks..etc. When surfaced with factory applied colourd slate granules, POLYFLAME is ideal as an exposed top layer.

Total impermiability for total waterproofing.
 Excellent resistance to aging and weathering.
Outstanding bond ability and seam integrity.
 Flexibility at low temperature.
 Stability at high temperature.
 Very high resistance to impact and puncture.
Simple single layer installation (reduces labour cost)
Variety of finishes for exposed and covered applications.
High tensile strength and tear  resistance
Very good puncture resistance.
Excellent for mechanical anchorage·
POLYFLAME  is installed by torch welding method, loose-laid or fully bonded to substrate. When loose-laid, only laps are bonded together. Peripheries and protrusions are sealed according to specifications.


The underside of the membrane should be torched just enough to superficially melt the bitumen. Excessive heating may damage the reinforcement. Overlaps should be re-heated from the top and resealed with a trowel to ensure seam integrity. For details of installation methods and flashing requirements, consult the relevant BITUMAT Design.


Available in two basic finishes:  
Black smooth finish with polyethylene  surfaces for covered applications.
Granule surfacing for exposed applications. Fine sanded upper surface in 3,4,5, mm are also available for covered applications.

For flat areas

1 mt.1.13 M2/M2 per layer

For 30 cm. girth flashing

0.35 M2/Mt/ length

Average wastage

3 - 5%


POLYFLAME complies with the requirements and tolerance levels of :
