Corle's Commitment to Green


The color green has always held a place of high importance for Corle Building Systems. It has been the primary corporate color since our company's beginning. In recent years, however, "Corle Green" has come to represent our commitment to providing our customers with environmentally friendly processes and products.

Keep in mind, Corle Green is not a pre-engineered Green building, per se. It is a part of the entire Green Building process. Corle Green is about the efficiency of the materials we use -- recycled and recyclable (steel), "cool" colors for wall and roof panels, wall and roof insulation that can reduce energy use, etc.

The creation of a Green building is taking "materials efficiency" (Corle Green) and integrating it into a building's total design, providing environmental quality enhancement, water and energy use efficiency, operations and maintenance optimization, occupant health, employee productivity, waste reduction, minimal environmental impact, etc.

The Benefits of a Green Building:

Environmental Benefits

• Enhance and protect ecosystems and biodiversity
• Improve air and water quality
• Reduce solid waste
• Conserve natural resources

Economic Benefits

• Reduce operating costs
• Enhance asset value and profits
• Improve employee productivity and satisfaction
• Optimize life-cycle economic performance

Health and Community Benefits

• Improve air, thermal, and acoustic environments
• Enhance occupant comfort and health
• Minimize strain on local infrastructure
• Contribute to overall quality of life


Recycled Content

Corle Building Systems uses recycled materials in the manufacturing process. Recycling reduces costs, while conserving energy and natural resources. In the construction industry, recent interest in recycling has been driven largely by the US Green Building Council's Leadership in Energy and Environmental Design (LEED®) rating system. The LEED rating system only promotes the use of materials with high levels of recycled content.

At the end of their useful life, about 88% of all steel products and nearly 100% of structural steel beams and plates used in construction are recycled into new products - an amazing reclamation rate!

Structural Systems and Components: Steel Joists

Cold-rolled steel framing typically contains 20-25% recycled material (10-15% post-consumer content), though some manufacturers have in excess of 90% recycled content. Steel framing is also recyclable at the end of the building's useful life.


"Cool Roofs"


In general, a "cool roof" is one that has relatively high solar reflectance and high thermal emittance. Corle CoolColor™ roof panels are manufactured with reflective TRINAR® 70% Fluoropolymer PVDF resin-based finish. Durable TRINAR® on Corle CoolColor™ panels provides reflectance and emissivity to meet ENERGY STAR® requirements.

Corle CoolColor™ panels provide the benefits of lower energy costs, increased roof life expectancies, superior roof color choices, and a cooler, cleaner, "Greener" environment for all of us.

The Ecological Benefits of Metal Roofing merits inclusion in the list of "environmentally friendly" or "green" roofing materials.




Metal roofing's durability can virtually eliminate the need to use future raw materials to produce roofing. Other roofing materials can break down due to changing weather cycles. Metal roofing is not affected such cycles. Metal is the material of choice for sustainability.

Recycled Content

Most metal roofs have recycled content ranging from 25% to 95%. Conventional roofing shingles have much shorter lives and use oil-based products as their primary raw material. Some state and local entities include metal roofing on their list of "green" and recycled content products.


Metal roofing is 100% recyclable. Conventional roofing products are disposed of by the ton in landfills across the country.

Low Weight

Depending on the product, metal roofing has a weight that is from 1/3 to 1/8 the weight of conventional shingles or slate roofing. In many instances, metal roofing can be installed over conventional roofs, eliminating the need to remove the old roof and eliminating the need to dump the old materials into landfills.

Product Safety

Metal roofing and the finishes used on it, are inert, safe materials that do not pose a health risk. Metal roofing in noncombustible.

Energy Efficiency

Many available metal roofs are being documented to meet Energy Star requirements. Meeting solar reflectance and thermal emittance standards can have a tremendous impact on energy usage by reducing air conditioning needs, thereby reducing the pollution created by the production of the energy used. Metal roofing dissipates heat very quickly. Other materials have greater thermal mass and will continue to radiate captured heat into the structures beneath them, even when the sun is not shining.

Metal roofing's many benefits, including sustainability, recycled content, recyclability, low weight, and energy efficiency, far outweigh virtually all other roof systems from an ecological standpoint.   (Source: Metal Construction Association)



Indoor air quality is a growing concern with today's tighter construction practices for buildings. According to the U.S. Environmental Protection Agency, most people spend about 90% of the time indoors where "thousands of chemicals and biological pollutants are found", thus negatively affecting their health. That is why Corle Building Systems offers Bay Industries Insulation to our customers. Bay Industries has made a point to achieve the highest possible product certification - "Greenguard Certification™". Greenguard Certified Products can reduce indoor air contaminants and promote a better indoor environment.

What is the Greenguard Certification Program?

The Greenguard Certification Program was founded in 1999 to establish a true third party certification based on proven emissions criteria used by U.S. Environmental Protection Agency, the state of Washington, the U.S. Green Building Council's LEED program, OSHA and the World Health Organization.

Greenguard Certified Products must pass rigorous emissions testing for certification. Critical components (such as volatile organic compounds, formaldehyde and other product specific components) are monitored quarterly. Fiberglass loose fill and batt insulation products from Bay Industries meet the Greenguard Certification Program's establishment emission standards.
