SPF Roofing

SPF Roofing

The U.S. non-residential roof market accounts for approximately 60% of all U.S. roofs. Over a 30 year life span, Spray Polyurethane Foam (SPF) roof systems have proven to provide a cost savings of between 10% and 50% less on average than comparably insulated membrane roof systems.

Sprayed Polyurethane Foam has been used as a roofing and insulation material for over 45 years. During this time, foam roofing systems have proven to be dependable, long lasting, and very affordable. Today there are foam roofs that have been in place for decades, and by all appearances they should be able to last indefinitely as long as they are properly maintained.

Spray Polyurethane Foam roofs carry a UL 790, class A Rating, which is the highest Fire Resistance Rating obtainable.

Duratite™ is a closed cell foam, so it is waterproof, but the UV rays alone degrades foam 1/8" per year. By coating the foam, you can protect it from UV rays. Rhino offers an acrylic topcoat and a silicone topcoat as part of our Duratite™ roofing system.

A key advantage of acrylic topcoats is that they can be continually recoated, so you can renew and protect your roof year after year. Acrylic should be applied when the temperature is higher than 50°F. Most acrylic coatings are highly reflective white and can reflect sloar heat and help keep roof temperatures low. Acrylic coatings are water-based, breathable, UV and weather resistant. They cure in about 4 hours.

Silicone coatings are inorganic coatings based on solvents, not water. They are breathable, UV and weather resistant. Silicone coatings are popular in cold climates. Apply when the temperature is above 40°F. These are moisture cured meaning moisture in the atmosphere acts as a system catalyst. Low humidity areas will require longer cure times or the addition of a catalyst.
