We hear this question often. And we don’t have a single clear answer. In the vast majority of cases, new ENERGY STAR™ windows are more insulative which helps keep the heat out (or in depending on the season). However, choosing the right replacement ENERGY STAR windows makes a difference in just how well they make your home more comfortable. Because we’re in Texas, we’re going to focus on how today’s windows help keep your home cooler than older windows.

Dual Pane Windows

Dual (and triple) pane windows make a difference in homes comfort because the air, or other gas, in between the window panes act as insulation. When you put your hand on a single pane window, it’s the same temperature as the outside. With multiple panes, the air/gas between reduces the heat transference into the home.

Better Construction

Assuming you choose new windows from quality manufacturer, they’re going to be better constructed than what a mass builder typically installs. Better construction includes things like welded frames which leak less air. Of course, the air leakage of each window you’re considering can be found on the National Fenestration Rating Council’s rating sticker.

Low-Emissivity (Low-e) Glass

Perhaps the biggest difference in new ENERGY STAR windows and older windows is the Low-e glass. Sunlight (aka solar energy) contains three types of light; UV, Visible and infrared. Low-e glass has a special coating that’s virtually invisible to the naked eye but helps reflect UV and infrared light without much impact on the visible light. This helps keep your home cooler in the summer without impacting natural light. It also helps keep heat in the home during cooler months.
