Q. WHAT IS EPDM?
A. EPDM stands for ethylene propylene diene monomer. It is a single-ply roofing system based on a high-performance synthetic rubber compound. It is widely praised for its outstanding weathering characteristics in any climate and has an excellent performance record. Because of this record, it is an ideal choice in low-slope commercial roofing. EPDM has been used successfully in the roofing industry for more than 40 years and, in that time, has proven to be a reliable, high-performance material. EPDM is lightweight and provides strength, high wind uplift performance, and versatility.
Q. WHAT IS TPO?
A. TPO stands for thermoplastic polyolefin. It is a single-ply thermoplastic roofing membrane and an economical choice for commercial roofing. It is one of the fastest growing commercial roofing products in the country because of its installation and performance advantages. It has excellent heat-reflective and energy-efficient qualities. It is praised for being lightweight, durable and low maintenance.
Q. WHAT IS SBS?
A. SBS is a modified bitumen roofing system. It provides excellent resistance to fatigue and elongation, while providing the strength of a glass-reinforced polyester mat. Many SBS systems has excellent solar reflectivity as well as durability. It typically comes with several choices in granule surface color and can be installed by hot asphalt, heat welding, mechanical attachment, and cold-applied adhesive. It is praised for being flexible in application, low maintenance, and lightweight.
Q. WHAT IS BUR?
A. Built-up roofing (BUR) is a time-tested, reliable method for installing a new commercial roof. It has been in use for more than 100 years. BUR consists of alternating layers of multiple plies of roof felts and bitumen. The result is a finished membrane. The bitumen used in BUR is typically asphalt or coal tar. BUR is easy to repair and is low maintenance. It is praised for its durability, reliability, resistance to weathering, thermal performance, and uplift performance.
