Will replacing my old 20 year old patio door with a new door be significantly more energy efficient?

Our sliding glass doors are 20+ yrs old. We’ve had estimates done and one guy said that even a new sliding glass door would let in some cold air because its a large glass surface. He recommends just repairing our existing doors. While I like saving money, is this true or can we drastically improve our energy efficiency with new doors?

Yes, depending on what kind of door you get.

The newer doors are much better made just go to home improvement store and look at them.

IF your existing doors are duo pane, you will not save appreciably by adding new doors…large areas of glass are cold when it is cold outside…if you have no real drafts from your doors, it is simply that even the best of glass is only about R4…and that is lousy when insulation numbers are being tossed around. It is the nature of large open panes of glass…I have a room that is nothing more than 42 feet of insulated patio doors! And without a lot of heat, it is downright cold in that room. If the doors look good, are double panes, have them repaired and save the money.

We have built 3 homes in the last 14 years and have never had cold air coming in through the sliders or patio doors. All our windows & glass doors in the homes were vinyl, low-E energy efficient. Because of them we have always received energy discounts. You would notice a definite change by upgrading to low-E.
