What is Low E3 Glass?

Low E3 glass is low U-factor glass that has 3 layers of an extremely thin metallic coating. The low U-factor means the glass allows a low amount of heat to escape, making it ideal for colder climates like Ohio's. E3 glass has 3 layers of a metallic coating that allows light in, while rejecting solar heat and blocking up to 95% of the suns UV rays. Low E3 glass helps retain heat in your home during the winter and keep heat out during the summer, boosting your home's energy efficiency.

WHY INFINITY FROM MARVIN ULTREX FIBERGLASS?

Benefit

Infinity from Marvin

Fibrex® Composite

Vinyl

Our fiberglass transformed window materials, our windows will transform your home. Unlike vinyl and vinyl composites, fiberglass resists expanding, contracting, and warping with changes in the weather. It keeps a tight fit and doesn't stress seals that can cause leaks and loss of energy efficiency. Replacing windows can be stressful; with Infinity from Marvin, you'll only have to do it once.
