Sprayed polyurethane foam (SPF) technology has been performing as an excellent means of insulation for over 50 years. When the polyurethane technology was first introduced, it was used as a barrier of heat and cold transfer in refrigerators. Since then, it has become a popular means of insulating a building, keeping the heat inside the building during cold months, and keeping the cool, air-conditioned air from escaping the building during the warm months.
These systems are ideal for avoiding a costly and time-consuming roof replacement when your current roof is not capable of performing as necessary. SPF roof systems are spray applied directly over your existing roof, creating a monolithic, closed cell waterproofing layer with custom insulation, providing excellent resistance to heat and cold transfer. This allows you to reduce cost and energy usage associated with creating a comfortable temperature inside the building.
The AcryShield SPF Roofing System is National Coatings’ spray foam system. This system can be applied over BUR, asphalt, concrete, metal, Mod Bit, and wood substrates. Initially the SPF is applied directly over the roof deck or existing roof, a layer of AcryShield base coat is then sprayed on top of the SPF providing a foundation layer of waterproofing with superior adhesion. Next, an AcryShield topcoat is applied, offering outstanding UV protection, longevity and brightness. Our topcoats are formulated to provide superior resistance to dirt pick-up from air borne contaminants, which allows the coating to remain highly reflective. Finally, a layer of RoofGuard Granules may be embedded into the topcoat for appearance, as well as, impact and foot traffic protection. These granules also improve traction across the rooftop while providing enhanced durability.
