A 'second generation' single ply product , Hi-Tuff marries the advantages of previous generation materials while eliminating their limitations.

Hi-Tuff roofing systems are based on Hi-Tuff T.P.O. membrane; a copolymer of polypropylene and ethylene propylene rubber that has been formed into a membrane sheet and internally reinforced with a heavy duty polyester scrim. A 'second generation' single ply product , Hi-Tuff marries the advantages of previous generation materials while eliminating their limitations. The result is a roofing membrane that is faster and easier to install yet offers outstanding resistance to weathering, temperature extremes, ultraviolet exposure and a wide variety of industrial chemicals.

Membrane Alternatives COLOURS: Standard Hi-Tuff colours are white, grey and tan. Custom colours are available on special order, subject to minimum quantities and cost surcharges.




Hi-Tuff is a thermofusible membrane manufactured in different roll widths. The membrane is welded together with a hot air gun to form a uniform membrane across the roof.

Hi-Tuff may be installed in a number of different methods, including "loose laid and ballasted" applications such as Lexican's standard Design B and C assembles. It truly stands out in mechanically fastened or fully adhered systems, where its heavy duty scrim reinforcement and super strong, heat-welded seams offer the superior protection needed for a fully exposed application. Featuring an attractive, contour hugging surface in a truly light-weight assembly, Hi-Tuff is the preferred choice for many commercial and industrial roofing applications.
