Henry 558 Aqua-Brite Aluminum Roof Coating is designed to reduce maintenance and add reflectivity to a roof surface. With its combination of premium aluminum flakes suspended in emulsified asphalt, Henry 558 reduces surface temperature and penetration of the sun's rays to the roof surface, helps reduce interior temperature, and protects the roof and roofing membrane by reducing heat absorption, asphalt oxidation, and rapid thermal dimensional changes.
