Frequently Asked Questions About Energy-Efficient Windows

Many homeowners are looking for ways to make their homes more energy-efficient. One of the best ways to accomplish this is to install energy-efficient windows in your home. 

Read on as we answer the most frequently asked questions about energy-efficient windows:

What Is a Gas-Filled Window?

This simply means that the manufacturers added an inert gas like argon between the gas panes. This special gas fill improves the insulation of the window, making it more energy-efficient. 

What Is Low-E Glass?

Low-E stands for “low emittance.” It means the glass of the casement or double hung windows is coated with a clear material to reduce the transmission of ultraviolet and infrared rays into your home, protecting your home’s furnishings and reducing your reliance on your heating and cooling systems.

What Is Insulated Glass?

Insulated glass refers to windows with two or more glass panes separated by insulation at the edges and a special gas fill in the center to improve the unit’s energy efficiency.
