Imagine how much money you could save on your energy bill if only there were a material that let in light but also kept heat from seeping through. Glass! It’s the perfect insulator on your patio doors!

The right kind of glass doors can save an average homeowner around $300 per year on heating or cooling costs because single pane glass leads to higher bills while good insulation will keep them low with no-fuss installation.


Many homes across the country have patio doors to allow a fresh breeze in and out of their living space. If you’re lucky enough to live where it’s not too hot or cold, then one glass pane will be sufficient for keeping your home cool while using less energy than with two panes. But if you are unlucky like me, who lives somewhere that is constantly experiencing extreme temperatures all year round (I’m looking at YOU Myrtle Beach), more than just one panel may do wonders for my comfort level!


Double-paned glass doors are not more energy efficient just because of the second layer of glass. More importantly, it is a space between the panes that is filled with gas such as argon or krypton.


To further insulate glass, manufacturers coat it with a low-emissivity or Low-E coating. This material is made of tiny metallic particles that reflect heat either indoors in the winter or back outside during summer months. Some experts even estimate this increased layer on your windows is like adding another whole pane to them!


The most insulating frame materials are fiberglass and vinyl. Wood is not far behind, but there’s a lot of upkeep required for wood frames. Aluminum isn’t as good at insulation, but people still love it for its strength and durability in hurricane-prone areas.
