    How to choose a sliding glass door

    Key things to decide before you order.

    • Measure the rough opening

      Measure width and height at three points and use the smallest. If your opening does not match a listed size, ask for a custom quote.

    • Panels and stacking

      Two-panel sliders suit most patios. Multi-slide doors stack several panels to one side for a much wider opening.

    • Energy performance

      Thermally broken frames and low-E double glazing limit heat transfer. Check the ratings against your local energy code.

    • Plan the install

      Exterior doors need careful leveling and flashing to stay watertight. Many owners hire a pro for this part.

    Follow our measuring guide before you order, and read the install guide if you are replacing a door in a load-bearing wall. Free finish samples help you match window frames and trim.

    Frequently asked questions

    Quick answers about sizing, installation and delivery.

    What size should I order?

    Measure the rough opening width and height at three points and use the smallest. If your opening does not match a listed size, request a custom quote.

    Should I install it myself?

    Interior doors and frame kits are good DIY projects. Exterior sliding doors and windows need accurate leveling and flashing to stay watertight, so many owners hire a pro.

    Are the frames energy efficient?

    Exterior doors and windows use thermally broken aluminum with low-E double glazing to limit heat transfer. Interior doors use tempered glass for safety.
