Enjoy a simplified PVC roofing installation and lower material costs than other membrane attachment methods. With the Firestone PVC Invisiweld System you get all the durability of PVC roofing, plus VOC-free application that's friendlier for crews and business operators.

The Firestone PVC InvisiWeld System is a mechanically attached high-performance, non-penetrating roofing system that requires fewer fasteners while still providing high wind uplift ratings. Compared to other mechanical attachment methods, InvisiWeld installation is simpler, less disruptive to building occupants, and less costly.


InvisiWeld application is VOC-free and features induction welding of Firestone PVC membrane to specially treated Firestone PVC InvisiWeld Plates. Induction welding fuses the Firestone PVC membrane and PVC InvisiWeld Plate together, reducing or eliminating the need for separate insulation plates and fasteners, and may also reduce the total number of fastening points of the roofing system. In addition to reducing material and labor costs, InvisiWeld application is well suited to many climates, including cold environments where adhesives and asphalt are difficult to use.

Firestones PVC InvisiWeld System has the same advantages as the rest of the Firestone PVC system family. Firestone PVC membranes resist aggressors you can see, like impacts, punctures, and many chemical or biological materials, but also the ones you can't see, like UV. Firestone PVC is a reflective, cool roofing solution that improves building energy efficiency while providing long term weatherability. The InvisiWeld System also carries standard industry approvals like Factory Mutual (FM).


Features and Benefits

Designed for Strength, Designed to Stay

Installation Is Business as Usual

PVC roofing is known to enjoy a long service life when properly installed and maintained. It is highly resistant to damage from impacts, punctures, chemicals, fire, and wind. Firestone PVC InvisiWeld is a mechanically attached system that provides high wind uplift ratings. What's more, Firestone PVC single-ply roofing membrane formulation has proven to be a durable, long-term commercial roofing solution, with more than 25 years of quality performance in the market

Many roofing installation methods rely on petroleum or chemical-based products with high VOC content, but not Firestone InvisiWeld. VOC-free application features Firestone PVC InvisiWeld Plates to PVC membrane using an induction welding tool, so there are no harsh fumes during installation and business operations don't have to be interrupted

Potential for Great Energy Savings

Allows for an Extended Roofing Season

PVC roofing systems are typically highly effective in warmer climates due to their reflectivity and durability. InvisiWeld is no different. Available in white, the InvisiWeld system is a highly reflective, cool roofing solution for low slope roofs that offers great weatherability and ozone resistance. Heavy rain, high wind, or hot sun, Firestone PVC InvisiWeld can stand up to it all

What if you could conquer more roofs through summer, winter, spring, and fall? With Firestone, you might be able to. The InvisiWeld System allows some contractors to extend their roofing season as InvisiWeld functions well in many climates, including cold environments where adhesives and asphalt may be difficult to use

Excellence and Options Come Standard
