The UltraPly TPO InvisiWeld system from Firestone is a non-penetrating mechanical fastening solution that greatly reduces labour while increasing the wind uplift resistance of the Firestone UltraPly TPO membrane.
This VOC-free system features TPO-coated Firestone UltraPly TPO InvisiWeld Plates attached to the UltraPly TPO membrane using an induction welding tool. The InvisiWeld System meets or exceeds Factory Mutual (FM) approvals and requirements.
The roofing season can be extended since the InvisiWeld System functions well in many climates, including extremely cold environments where adhesives and asphalt are difficult to use. Eliminating insulation seam plates and fasteners reduces installation time and labor costs. Membrane waste is less because a 6" in-seam lap is no longer needed. This system requires less material for perimeters and corners than other attachment methods.
