How Energy-Efficient Windows Work

How Energy-Efficient Windows Work 

More and more energy savings and efficiency have become factors homeowners consider when diving into home improvement projects. It can get confusing with windows because they all look fairly similar, causing homeowners to wonder how energy-efficient windows differ from others. To help clarify how energy-efficient windows work, we break down the efficiency features that help reduce the heat transfer between the interior and exterior of your home to keep you cool in the summer and warm in the winter.

Glass Coating

Energy-efficient windows also often use low-emissivity (Low-E) coatings on the glass. These coatings reflect heat into the room, reducing the heat lost through the window. Low-E coating also blocks the sun’s rays and keeps the heat inside when it’s cold and outside when it’s hot. The main benefit of the coating is to help save you on heating and cooling costs.

Multiple Panes & Insulated Glass

Double-paned and triple-paned glass increases the blocking of UV rays. When UV rays are blocked, your home will be more comfortable year-round. Energy-efficient windows will use insulated glass, two or three panes separated by a gas-filled space. This space reduces the amount of heat transferred through the window, improving the window’s insulating properties.

Window Frames 

The frames of energy-efficient windows are often made of materials with low thermal conductivity, such as Ultrex® fiberglass. Ultrex® is made from a combination of glass fibers and thermoset resin that produces a material that is strong, rigid, and stable, yet lightweight and easy to work with. Ultrex® window frames are resistant to cracking, warping, and fading even in extreme temperatures and weather, an excellent insulator, low maintenance, and can be molded into a variety of shapes and sizes to provide design flexibility and customization. It is a long-lasting material well suited for window replacement projects. At Veracity Window & Door, we install Ultrex® energy-efficient windows.


Energy-efficient windows also typically use high-quality weatherstripping to seal gaps between the window and the frame, reducing drafts and heat loss.

Windows can be a thermal black hole if they lack the proper glass, coatings, frames, and weatherstripping. It’s believed that one-third of the money spent on heating and air conditioning goes out the window. But with the many new technologies of energy-efficient windows, all you have to do is worry about getting your old windows replaced.
