For all who have been searching for attractive, energy-efficient, high-performance vinyl windows, let us clear the way. The Endure™ Window Series has been independently tested to meet strict energy efficiency standards and is ENERGY STAR® certified. Endure windows come standard with the highest-quality frame and sash designs and ComforTech™ Warm Edge Glazing, a high-tech glass package that measurably improves thermal performance—for less heat loss, warmer glass temperatures and reduced interior condensation.

For the Endure vinyl window line, ProVia has chosen the optimum levels of technology to make a window that will work continually at peak performance. Endure windows provide all that you would expect from energy-efficient, high-performance vinyl windows, using much less energy to stay warm in the winter, cool in the summer, and provide more comfort all year round.

ProVia’s Endure vinyl windows offer maximum energy efficiency, while displaying stunning beauty.


ENERGY STAR is a U.S. Environmental Protection Agency (EPA) voluntary program that helps businesses and individuals save money and protect our climate through superior energy efficiency.
