The Original Polarhide- Beware of Cheap Imitations!
The Ideal SPF Roof Foam Coating
Polarhide has unique advantages as a roofing-foam skin for Spray Applied Polyurethane Foam (SPF ).
Both products are designed to solve the same problem set (i.e. cool and waterproof a roof). Both are seamless and block roof heat; foam by insulating and Polarhide by reflecting. Polarhide blocks 90% of the heat impacting a roof before the 2.0” of 2.7lbs+ closed cell foam has been touched. It is hard to imagine any combination of heat barriers that can perform like Polarhide and SPF. Polarhide can be installed on a wet roof, withstands standing water for the life of the 20 year warranty, and is not subject to weather in that it can be installed in high or low temperatures, high or low humidity, during rain fall (heavy rain stops work and makes it difficult to install but that I not a Polarhide limitation).
Polarhide has unique features always in demand in the roof foaming business:
- Foam on flat roofs is very vulnerable to standing water. Polarhide eliminates the standing water problem for foam.
- Polarhide is a non-chalking, non-yellowing, flexible roof epoxy.
- Epoxies are known to have a better bond with Polyurethane foam than polyurethane.
- Foam and Polarhide Self-adhere –wind uplift ratings are the best in the roofing industry.
- White roof shingle granules can be embedded in the Polarhide topcoat to make a tough non-skid surface.
- Many roof coatings presently used on foam roofs are water based. Acrylics and elastomerics are water based . The water in standing water on a roof bonds with the water in the water based coating causing the coating to break down irreversibly. Thus exposed to the sun, UV will corrode the foam. Polarhide, the epoxy, can withstand standing water for the life of its 20 year warranty
- The polyurea based roof foam coatings have a unique set of problems that Polarhide is not subject to, for example, polyurea must be delivered at a high temperature. When this hot coating hits small blemish spots in the foam a small hole is formed there. The solution offered by the polyurea tech reps requires that silicone be applied to these holes. There may be thousand of these holes. Polarhide is a cold applied liquid epoxy and it does not react with these blemishes in the foam thus eliminating this problem.
- Foam is critically vulnerable to humidity, wind and temperature. In project terms this means your expected 8 hour day of foaming is often a 4 hour day - or worse - you do not work at all. Polarhide can be installed in any weather from a very cold 30°F to very high temperatures where Polarhide thrives. As rain first falls on a roof you can continue with Polarhide without panic.
