A well-insulated and energy-efficient patio door can make a big difference to your home. Apart from preventing drafts, it can ensure that your interior is comfortable and your home’s energy efficiency is at optimal level.

If you’re shopping for a new patio door, Woodbridge Home Exteriors — a trusted provider of windows and doors — discusses some essential factors to look for.


Your choice of material can have an effect on the energy efficiency of your patio door. For example, fiberglass and steel with polyurethane foam are generally considered energy-efficient. They can also have additional insulation, and they won’t shrink or swell despite fluctuating temperatures.

Take note of the distinction between double and triple-pane windows too. The spaces between the panes in these windows are usually filled with air or gases, enabling the glass and the door to have better insulation.


Glazing level refers to the amount of glass in patio doors. Obviously, an opaque door has no glass. Meanwhile, doors with half-lite are usually made of half glass, and those that are greater than half-lite are mostly made with glass.


U-factor measures the rate of heat transfer, which typically ranges from 0.25 to 1.25. Make sure to look for a low U-factor rating as this means the door has better insulating power.


SHGC, or solar heat gain coefficient, refers to the capacity of the door to prevent solar heat gain. It ranges from 0.25 to 0.80.
