A sash or panel that does not close tightly can let in a steady draft, and a thin frame can transfer outdoor heat or cold much faster than people expect.

If the door system is not sealed well, warm moist air can work its way indoors and raise the load on the air conditioner.

A few signs usually point to an inefficient patio door: - A noticeable temperature difference near the door
Drafts around the sides or threshold Condensation on the interior glass Faded flooring or furniture from direct sun Difficulty opening, closing, or locking the door
