The Climatemaster® roof series is designed for any climate and almost any condition. Climatemaster® roof systems have superior insulating R-values as well as strong snow load ratings. A Climatemaster® roof is the best way to protect your sunroom investment and your home. Roofs range from 3” to 6” thick with1 1/2# or 2# density EPS (expanded polystyrene) depending on your building code requirements. Roofs are thick gauge stucco-embossed aluminum protected by Krystal Kote® finish to prevent scratches and discoloration. The unique two-piece mullion system joins the roof sections together to create a gasket-like compression seal that will provide years of weather tight protection for your patio enclosure.
