UltraPly TPO InvisiWeld System

UltraPly TPO InvisiWeld System

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, 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 extremely cold environments where adhesives and asphalt are difficult to use. Reducing insulation plates and fasteners reduces installation time and labor costs. This system requires less material for perimeters and corners than other attachment methods.

Quick and easy installation method:

  1. Fasten Firestone UltraPly TPO InvisiWeld Plates to Firestone approved insulation boards in a grid pattern with Firestone All Purpose or Heavy-Duty fasteners.
  2. Place UltraPly TPO membrane over the grid of InvisiWeld plates.
  3. Use induction welding tool to secure each plate to the underside of the TPO membrane – takes just 6 seconds!
