Your ‘New’ Vinyl Windows May Use Inefficient Materials.

Endure Windows from ProVia use something 700x more efficient.

It’s a big promise. Better thermal breaks. Better protection against condensation. And it’s accomplished by incorporating INNERGY® Thermal Reinforcements.

Innergy is the innovative, energy-efficient alternative to aluminum, with added insulating properties making it 700x better.

As the next-generation of thermal reinforcement for the industry, Innergy is able to deliver a quantum leap above aluminum in how windows perform. It even helps provide better protection against condensation.
