Contributions to Green Building Standards

Contributions to Green Building Standards

The Duro-Last single-ply roof membrane can help buildings obtain credits under the U.S. Green Building Council’s LEED® (Leadership in Energy and Environmental Design) rating system, as well as GBI’s (Green Building Initiative) Green Globes® certification. Both programs promote sustainable building management and construction practices.

The following tables refer to the flagship Duro-Last membrane. Additional LEED/Green Globe contribution data can be found on the Product Environmental Profiles listed on our website: Duro-Last.com/sustainability.

A Sustainable Choice for Your Building

A Sustainable Choice for Your Building

Across the world, extreme weather and prolonged heat waves are setting — and breaking — records. Worse, the localized urban heat island (UHI) effect has caused the annual average temperature in a city of a million people to increase between 1.8°F and 5.4°F, according to the U.S. Environmental Protection Agency. This number can jump to as high as 22°F warmer in the evening hours.1 Understandably, this has driven a growing demand for cooling technology.

Cooling is now the fastest growing use of energy in buildings, and ACs and electric fans already account for about 10% of all global electricity consumption. This is one of the most critical blind spots in the energy world today — by 2050, cooling demand could more than triple.2 While greater access to much needed cooling services is a good thing, it places a major strain on our energy infrastructure.

A building’s envelope — the parts of a building that form the primary thermal barrier between interior and exterior — plays a key role in how much energy is required to heat and cool a building.

Committed to Reducing Our Environmental Impact

Committed to Reducing Our Environmental Impact

Duro-Last is committed to promoting sustainable roofing practices through our products, services and corporate culture. Sustainability has been a part of the Duro-Last culture for more than 20 years.

• Duro-Last was the first manufacturer to publish a product-specific PVC Environmental Product Declaration (EPD) for single-ply membranes, reporting the life-cycle environmental impact of each of our membrane products.

• During production, edge trim and scrap is kept clean and recycled back into production, eliminating virtually all manufacturing waste.

• Manufacturing utilizes a closed-loop water cycle, reducing wasteful water discharging.

• Recycle Your Roof Program recycles membranes into high-quality commercial flooring, walkway pads, rooftop pavers and concrete expansion joints.

Duro-Last was recognized with the 2017 Excellence in Recycling Award by the Michigan Recycling Coalition for our commitment to recycling and sustainable materials management. The award recognizes Michigan-based organizations that show leadership and excellence in recycling and waste diversion.

Duro-Last also leads the roofing industry with the most certifications under NSF/ANSI 347 and is one of only two manufacturers to achieve the highest-level platinum certification:

Platinum Certification

– Duro-Last® membrane

– Duro-Last Rock-Ply® membrane

– Duro-Last Shingle-Ply® membrane

Gold Certification

– Duro-Tuff® membrane

– Duro-Fleece® membrane

– Duro-Fleece Plus® membrane

– Duro-Last® EV membrane

The NSF American National Standard for Sustainable Roofing Membranes — NSF/ANSI 347 — is the leading consensus standard for evaluating and certifying sustainable attributes of single-ply roofing membranes over their entire life-cycle. Using a point system to evaluate roofing products against established prerequisite requirements, they focus on the five key areas of:

Product design

Product manufacturing

Membrane durability

Corporate governance

Innovation
