Firestone UltraPly™ TPO InvisiWeld™ System is a high-performance, non-penetrating TPO membrane fastening system. The mechanically attached system provides high wind uplift ratings. Installation is simplified and requires less material for perimeters and corners than other attachment methods, reducing labor and material costs.
This VOC-free application features Firestone UltraPly TPO InvisiWeld Plates attached to the UltraPly TPO 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 cold environments where adhesives and asphalt may be difficult to use. Reduces the need for insulation plates and fasteners.
