The TremPly KEE and KEE FB (Fleeceback) Single Ply Roofing Systems are designed to provide superior performance and exceptional value. 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 resistance to fungus, algae and fire makes TremPly KEE systems one of the most sustainable roofing systems available.

High performance, water-borne TremPly KEE FB WBII Bonding Adhesive is formulated to adhere KEE FB (Fleece back) membranes to such approved substrates as polyisocyanurate insulation, gypsum-based coverboards and approved base sheets. By being both VOC compliant and environmentally safe, it is especially useful in applications requiring a high degree of sustainability. TremPly KEE FB WBII Bonding Adhesive provides a very high initial tack strength, unlike many competitive products.

TremPly® KEE LV Bonding Adhesive is a low VOC, solvent-borne Nitrile/PVC polymeric adhesive used to adhere TremPly KEE membranes to horizontal and vertical surfaces; do not use with TremPly KEE FB (Fleeceback) membranes. Substrates approved with TremPly KEE LV Bonding Adhesive include wood, metal and for flashing (vertical) applications, and pre-approved polyisocyanurate insulation, approved gypsum-based coverboards and approved base sheets for horizontal roofing applications.

TremPly KEE LV Bonding Adhesive complies with all air quality districts in California and other regulated areas, making it the most environmentally-friendly, solvent-borne adhesive available in the USA. 

TremPly KEE Plus Stress Plates were created to enhance both load distribution and wind resistance for TremPly KEE Roofing Systems. They are engineered for all mechanically-fastened TremPly KEE Roofing Systems, including our 100-inch-wide membranes, exceed FM Global (FMG 4470) requirements for corrosion resistance and are FMG Approved for Class One Mechanically-Attached TremPly KEE Roofing Systems. 

TremPly® KEE Plus Stress Plates are manufactured from 0.47 in. (1.19 mm thick) AZ50 Galvalume-coated steel. Oblong in shape, they feature three-quarter inch (1.9 cm) radial corners, a 0.25 in (0.635 cm) hole in the center of the plate, a raised reinforcement area to resist deflection and 12 barbs to enhance wind resistance all within a compact 23/4” x 11/2” plate.

The TremPly KEE Protection Walkway is designed to increase rooftop safety with enhanced slip resistance, with an embossed, low-profile diamond plate design, and integrated reinforcement for additional membrane protection. The highly visible yellow color provides a direct path for rooftop traffic while the integrated reinforcement protects against possible damage from dropped or improperly handled materials. The TremPlyKEE Protection Walkway should be installed around hatches, doorways and other roof access points; around mechanical equipment that undegoes scheduled maintenance; or where there is frequent foot traffic.
