InvisiWeld Non-Penetrating Fastening System
November 19, 2009
Firestone Building Products is pleased to introduce the Firestone UltraPly TPO InvisiWeld System. It is a high performance, non-penetrating TPO membrane fastening system that includes a special TPO coated Firestone UltraPly InvisiWeld plate fastened with Heavy Duty, Heavy Duty Plus or Purlin fasteners and used to attach Firestone approved insulation boards. After laying out the TPO membrane over the plates, an induction welding tool is placed over each plate and within 6 seconds, the plate is welded to the underside of TPO membrane. It’s that simple! Saving you time, labor and material.
Other advantages of this system are: - Elimination of seam plates and fasteners, saving installation time.
- Elimination of half TPO sheets at perimeters and corners.
- A 3” lap means less membrane waste, as opposed to a 6” lap for in-seam mechanically attached TPO systems.
- Minimal wind flutter or membrane fatigue due to a more even load distribution over the membrane.
- Extended roofing season since the InvisiWeld installation works well in extreme cold environments whereadhesives and asphalt are difficult to use.
- Increased savings with material and labor due to no mechanical seam attachment and by following a simple grid-like pattern of induction welding the plates.
- High wind uplift ratings.
- Meets or exceeds Factory Mutual (FM) Approvals and requirements.
- VOC free roofing system.
Firestone Building Products is committed to continue to bring high quality products, systems and tools to the market that increase efficiency, productivity, and most importantly increase the profitability of our customers.
The new UltraPly TPO InvisiWeld System is offered in addition to traditional mechanically attached and fully adhered TPO systems; it’s an additional system using an innovative attachment method having unique advantages.
