An energy efficient home is a comfortable home! Making it either warmer or cooler; and will help in saving money on utilities, too. The type of glass material you choose is critical when it comes to energy efficiency!

Residential windows are generally referred to as either “single glazed” or “insulated,” dual panes. What’s the difference, you ask?

Single Glazed vs. Insulated Glass, the difference…
A single glazed window is constructed of a single pane of glass.  This means, this is the only barrier separating your home from the outside elements. A single glazed window can be up to 20-times less efficient than an insulated window when it comes to energy loss.

Insulated glass, or double glazed window, is constructed of two or more panes of glass, sealed with an insulated air spacer. Factory made insulated windows can be up to 100% more efficient than a single glazed equivalent.
Even if only one pane of glass is broken, the entire unit needs to be replaced because the seal has been broken.

UV protective coatings, LowE, is another option that prevents UV sun rays from penetrating through the glass, at a lower impact.

Even though the initial cost of insulated windows is higher than single glazed, insulated or double glazed windows will eventually pay for themselves by reducing energy costs, over time.
