Galvalume Metal Roofing Energy

The mixture of zinc and aluminum protects the galvalume metal against corrosion and rust helping galvalume typically last much longer than galvanized steel.

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. Many metal roofing systems are energy star labeled and meet other cool roof requirements in codes and standards. Welcome to galvalume biec international inc. 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.

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. Galvalume steel comes in various gauges that determine the quality and price. 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. Major costs of galvalume roofing.

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. 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. This is why light colored painted roofs have a better tsr total solar reflectivity rating than galvalume. 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.

Energy star also has a roof products component for cool roofing. Reflectance in relation to metal roofing refers to uv and infrared light rays being reflected from the roof surface. What a consumer will pay for a galvalume roofing system depends on the quality of the material. Epa s energy star program is familiar to many homeowners who see the label on appliances and electronic equipment.

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.
