TPO and PVC are heat-welded, single-ply membranes designed for long-term performance in commercial low-slope applications.

Key Benefits:

Consistently Welded Seams: Using a Leister Varimat hot-air welder (pictured left), membrane sheets are fused at a controlled temperature and speed, creating a consistent bond often stronger than the membrane itself—without relying on adhesives or tapes.
Watertight Performance: Welded seams provide excellent resistance to ponding water and long-term moisture exposure.
Energy Efficiency: Light-colored TPO and PVC membranes offer high solar reflectance, reducing rooftop temperatures and lowering HVAC demand.
Durability: Engineered for UV resistance and long-term weathering performance in demanding commercial environments.
Serviceable System: Damaged areas can be cut out and new membrane heat-welded in, restoring system integrity efficiently.
Extended Installation Season: Heat welding does not depend on solvent curing, allowing installation in a broader range of weather conditions.
