Product Specifications

A modified pvc based product, specifically designed for roofing & rainwater products.

Conventional PVC roofing technology requires the use of low molecular weight liquid plastisol polymers applied to lightweight fabrics to create a flexible membrane. Over time, UV, heat and environmental contaminants draw the plastisol (plasticizer) to the surface of the membrane where it's washed away by wind and rain. This plasticizer migration reduces flexibility and leaves the membrane susceptible to damage from thermal shock, hail impact and foot traffic. Additional effects of plasticizer migration on the in situ aging process can make the membrane difficult to repair, and subsequently impossible to maintain.
Fatra Coated metal is engineered using an alternate technology whereby a Plasticizer Free PVC, (non-Plasticised Polyvinyl Chloride) is used. This unique development vastly reduces the ageing process and the subsequent potential modes of failure.
This coating technology is then thermally bonded to hot dip galvanized steel with 4 added protective layers of epoxy polyester paint. The result is a high performance membrane coated steel product that remains flexible and ideally suited for roofing and guttering applications.
