Post Consumer Recycled Material
Post consumer recycled materials are those materials which have already served their initial purpose to a consumer and are then reclaimed rather than being discarded in traditional landfills. Common post consumer recycled materials include tires, aluminum cans, newspapers, plastic bottles and glass. Innovative companies are finding new ways to break down these materials and incorporate them into their processes. Post consumer waste is generally recognized as being more environmentally friendly because once materials reach the consumer they are more likely to end up in landfills.
Post Industrial Recycled Material
Post industrial recycled materials are those materials that have been recovered or otherwise diverted from the waste stream during the manufacturing process. This does not include used, reconditioned or remanufactured components.
Scrim
The reinforcing fabric that acts as a carrier for the polymer modified bitumen. The scrim contributes to performance characteristics of the finished product that include tensile strength, puncture resistance and fire resistance. The two primary fabrics for scrim include fiberglass and polyester. There is also a combination scrim which incorporates both of these fabrics.

LEED
The Leadership in Energy and Environmental Design (LEED) Green Building Rating System, developed by the U.S. Green Building Council (USGBC), is a third-party certification program and the nationally accepted benchmark for the design, construction and operation of high performance green buildings. LEED promotes a whole-building approach to sustainability by recognizing performance in five key areas of human and environmental health: sustainable site development, water savings, energy efficiency, materials selection and indoor environmental quality.
Low Temperature Flexibility
The ability of a membrane to remain flexible (resist cracking) after it has been exposed to low temperatures. Roofing membranes encounter extreme weather conditions and resisting cracking at low temperatures this is vital to the long-term performance of roofing membranes in colder climates. Low temperature flexibility is directly related to the amount of rubber incorporated in the membrane. Since the rubber modifier also increases UV protection, the better the low temperature flexibility, the greater UV protection a membrane will have. Therefore, low temperature flexibility is a vital criteria for warmer climates as well.
Mechanical finishes are raised features on metal panels. These features are mesa patterns, pencil lines, or stucco embossing. Mechanical finishes help to reduce oil canning and strengthen the panels. Garland uses mechanical finishes to increase the performance of our metal roof systems, and also to add to their aesthetic appeal.
