Galvalume Metal Roofing Energy

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.

Galvalume metal roofing energy.

This is why light colored painted roofs have a better tsr total solar reflectivity rating than galvalume. Epa s energy star program is familiar to many homeowners who see the label on appliances and electronic equipment. 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 includes roofing systems constructed using unpainted galvalume and clear acrylic coated galvalume as well as both architectural and wood frame products in standard colors.

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. 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. Reflectance in relation to metal roofing refers to uv and infrared light rays being reflected from the roof surface. Energy star also has a roof products component for cool roofing.

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

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. We are proud to announce that fabral has received energy star approval on many of their metal roofing products. 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.

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