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.

Such a roof can be reasonably expected to be some 50 to 60 degrees cooler than a dark color asphalt shingles roof. 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. 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. Galvalume steel comes in various gauges that determine the quality and price.

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. Many metal roofing systems are energy star labeled and meet other cool roof requirements in codes and standards. 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.

Energy star also has a roof products component for cool roofing. Major costs of galvalume 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. This is why light colored painted roofs have a better tsr total solar reflectivity rating than galvalume.

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. A measure of the success of this program is the fact that virtually all of the major steel companies worldwide have become licensees of biec. And galvalume as well as kynar 500 coated and coolroof rated g 90 steel offers exceptional heat reflectivity resulting in lower energy load on homes and hvac equipment resulting in improved interior comfort and energy savings for homeowners. The mixture of zinc and aluminum protects the galvalume metal against corrosion and rust helping galvalume typically last much longer than galvanized steel.

What a consumer will pay for a galvalume roofing system depends on the quality of the material.
