Firestone PVC KEE InvisiWeld™ System is a high-performance, non-penetrating PVC membrane fastening system. The mechanically attached system provides high wind uplift ratings. Plus, simplified installation reduces labor and material costs. Overall, installation is less costly for building owners versus fully adhered systems and less disruptive for building occupants.
This mechanically attached application features Firestone PVC InvisiWeld Plates attached to the Firestone PVC KEE membrane using an induction welding tool. The InvisiWeld System achieves Factory Mutual (FM) approvals.
The roofing season can be extended since the InvisiWeld System functions well in many climates, including cooler environments where adhesives and sealants may be more difficult to use. The InvisiWeld system reduces the need for insulation plates and fasteners. The Firestone PVC KEE InvisiWeld System is compatible with Firestone Polyisocyanurate (ISOGARD™) insulation, Firestone ISOGARD HD Cover Board, Structodek® H, Securock® or DensDeck® boards.
Pair simplified installation with the proven benefits of PVC KEE, and you have a long-term commercial roofing solution that's great for contractors, building owners, and occupants alike. Firestone's PVC KEE membrane formulation uses DuPont™ Elvaloy® Ketone Ethylene Ester, a solid plasticizer that bonds with the PVC to provide consistent and dependable plasticizer retention for the service life of the roof. The product formulation has proven in-market performance for 30 years, and we stand behind it with the Firestone Red Shield Limited Warranty.
