BEACHWOOD, Ohio — Tremco Roofing and Building Maintenance has added two tough, waterproof, easy-to-install single-ply roofing systems to its TremPly line: TremPly KEE and KEE FB (Fleeceback).

Both systems incorporate proven Ketone Ethylene Ester (KEE), which provides superior flexibility to accommodate building movement, as well as resistance to harmful UV rays and chemicals. Heavy duty reinforcement makes the systems extremely resistant to tears and punctures, and combines with maximum seam strength for durability and long-term performance. Their additional resistance to fungus, algae and fire makes TremPly KEE systems one of the most sustainable roofing systems available.

TremPly KEE and TremPly KEE FB single-ply roofing systems are available in mechanically attached or fully adhered configurations, with seams fused with conventional hot air welding.  They come in 45-mil and 60-mil thicknesses with a highly reflective standard white surface which could help lower energy use; tan and gray are also available, and all colors can help a business meet LEED requirements. 

Both systems carry extensive FM Global and Underwriters Laboratories approvals. They are available in conventional 74” or 100” wide by 100’ long rolls; customized, prefabricated roll widths and lengths also are available.

A range of adhesives are available to meet local environmental requirements, as are a line of pre-fabricated accessories designed to save time and money during installation, including walkways, protection mats flashing accessories and stress plates.
