Low-E Glass

If you have ever poured a hot drink in a glass container, you know how poor of an insulating material glass can be. Glass absorbs and transfers heat very easily, which can be a very costly problem for any home with a significant number of windows. Low-E glass, like our Zoe-e-Shield glass, is designed to help block out the sun’s heat and harmful UV rays. In fact, our Zo-e-Shield glass blocks 95 – 99.9 percent of the sun’s UV-A and UV-B radiation, which can reduce the fading or interior furnishings in addition to reducing the amount heat absorbed by your windows.


There are many low-E glass options including tints, reflective coatings, and multiple glass panes.


Double and Triple Paned Options

In the past, windows were only a single pane of glass that separated the interior of your home from the exterior. As we mentioned before, glass is an excellent conductor of heat, so single paned windows are excellent transmitters of heat into and out of your home.


Today, energy-efficient windows are available with two and three glass pane options with insulating gas-filled airspace to lessen the amount of heat transfer through the window.


Energy-Efficient Window Spacers

Rather than simply using metal framing as a window insulator, today’s windows utilize a thermally efficient spacer made of low-conductive materials that insulate against cold airflow and condensation. When combined with insulating dual or triple paned windows and low-E coatings, you get exceptionally energy-efficient replacement windows.


Energy-Efficient Materials

Although all varieties of windows can have different components and options, some of our windows offer superior energy efficiency. Fiberglass replacement windows, for example, offer superior energy efficiency to all other varieties of windows. Fiberglass is a low-conducting material that has very little expansion or contraction in hot or cold temperatures. This reduces the amount of airflow around the frame of the window—saving you money.
