Galvalume Metal Roofing Energy

Is the worldwide licensor of the technology and know how associated with 55 aluminum zinc alloy coated sheet steel better known as galvalume.

Galvalume metal roofing energy. This includes roofing systems constructed using unpainted galvalume and clear acrylic coated galvalume as well as both architectural and wood frame products in standard colors. Many metal roofing systems are energy star labeled and meet other cool roof requirements in codes and standards. Such a roof can be reasonably expected to be some 50 to 60 degrees cooler than a dark color asphalt shingles roof. Galvalume steel comes in various gauges that determine the quality and price.

The mixture of zinc and aluminum protects the galvalume metal against corrosion and rust helping galvalume typically last much longer than galvanized steel. This is why light colored painted roofs have a better tsr total solar reflectivity rating than galvalume. A highly reflective and highly emissive painted or granular coated metal roof is optimal for reducing energy consumption and can actually re emit up to 90 of absorbed solar radiation. For example a galvalume section that is 16 x3 known as a classic rib steel roof panel is 29 gauge steel and comes with a 25 year warranty.

Epa s energy star program is familiar to many homeowners who see the label on appliances and electronic equipment. What a consumer will pay for a galvalume roofing system depends on the quality of the material. Galvalume metal roof and siding panels are coated with a mixture of zinc and aluminum and siliconized coating to help resist scuffs and fingerprints better than a bare metal product. Major costs of galvalume roofing.

Energy star also has a roof products component for cool roofing. In my opinion a light colored metal roof will always outperform a galvalume roof in energy savings unless you live in an extremely cold area like some parts of canada. Welcome to galvalume biec international inc. In fact a high end kynar 500 white metal roof is energy star rated and classified as a cool roof by the cool roof rating council.

Reflectance in relation to metal roofing refers to uv and infrared light rays being reflected from the roof surface.
