Why "cool" matters

Cool roofs do two things: they reflect incoming radiation (reflectance) and help release trapped heat (emittance). As a result, a home or building uses much less energy, especially for cooling.  On a global level, cool roofs help lower emissions by reducing the amount of energy used by power plants. With lower rooftop temperatures, the ambient air outside is cooler which mitigates the "heat island" effect.


Why choose a "cool" metal roof?

The eco-friendly benefits of a metal roof are enhanced by cutting edge technology which render metal roofs a cool roof material.  In terms of efficiency, a cool metal roof outperforms other leading roof materials across a broad range of tests for reflectivity and emissive properties.  According to the Cool Metal Roofing Association, a cool metal roof can reduce energy consumption by as much as 40%.


About Kynar 500®:

Today's cool metal roofs are no longer limited to white or light colors because the Kynar 500® special pigments do not affect the visible color. As a result, darker colors can perform like light colors in terms of solar reflectance values. The Kynar 500® paint system features a Kynar 500® PVDF resin-based coating or finish that is highly durable and maintains stable color over a longer period than other finishes. Kynar 500® is a registered trademark belonging to Arkema, Inc. For more information, visit the manufacturer's website here.

Cool Metal Roofing Systems

"Cool" roofs are highly recognized as a significant part of sustainable, green design.  Energy-efficient mandates have highlighted the benefits of cool roofs, especially in areas of new contruction and Title 24 compliance in California.

What is a "Cool" roof?                                                           In general, a cool roof is one that does not absorb solar energy, thus establishing a much lower surface temperature. Unlike roofs made with conventional material, cool roofs are both reflective and highly emissive which means less heat gain in the building below. A metal roof system that uses a high-performance finish results in a cool metal roof that lowers a building's carbon footprint and overall energy consumption.

Westech Contractors, Inc. is proud to offer cool metal roofing systems that satisfy many of the requirements of today's high-performance and energy-efficient objectives.  Our cool metal roofing systems have many profiles and features, including durable Galvalume® steel combined with Kynar500® paint technology to give you a roof that meets the strigent criteria of today's building industry.
