About the Product

SPF is a closed-cell roofing material formed by combining two liquid components. When these two materials meet in the mixing gun, they expand 20 to 30 times their volume immediately, forming rigid polyurethane foam (PUF). This foam is sprayed on the entire roof to the desired thickness, usually 20 – 30mm, to form a seamless monolithic surface including flashing, penetrations and parapet walls. This eliminates seams and cold joints, the primary source of major leaks, and provides a durable waterproof covering that bond tightly to nearly any properly prepared surface.

For more than 30 years Sprayed Polyurethane Foam (SPF) has been used as a roofing and insulation material. SPF systems have been proven through comprehensive, independent studies to be dependable, long lasting, and very affordable. Their are foam roofs today that have been in place for more than 30 years, and if properly maintained they should be able to last indefinitely.

Sprayed Polyurethane Foam is lightweight – about 600g per square metre – and can be applied over most existing roof structures without exceeding the structural load capacity. Yet it's amazingly strong, easily withstanding foot traffic and other weight requirements. Since it can be applied directly over tar, IBR, Chroma-deck, corrugated, built up roofs, roof tiles, concrete, metal and wood. There is little to no need for strip, reducing the amount of time, disruption to the business and even reducing the clean up time.
