Energy Efficiency

A variety of factors make windows and doors more energy efficient.

The way the frame and sash are engineered and manufactured, type of glass used (single-, double-, or triple-paned), use of Low-emissivity ("Low-E") coating, presence of argon or krypton gas-filled insulated glass (IG) all contribute to a product's energy-saving capabilities. And with the ever-increasing cost to heat and cool your home, you can't afford not to choose the most energy-efficient windows and doors.*

As an ENERGY STAR^® partner, Vytex uses the latest advances in window and glass technology to maximize the performance and efficiency of your window investment. Our products help you stay warmer in the winter, cooler in the summer—and reduce your energy costs—through our exclusive line of energy-saving window features.
