What the AI looks for in Patio Doors
- Sliding vs hinged
- Choose a slider where swing space is tight. Choose a hinged French door for a wide, fully open look with clearance to swing. Swing clearance and furniture layout usually decide the type before style does.
- Operating configuration
- Specify which panel moves (for example XO or OX) as viewed from the exterior. Ordering the wrong configuration puts the moving panel on the wrong side of the room.
- Safety and glass
- Glazing must be tempered safety glass. Choose dual-pane Low-E and check NFRC U-factor and solar heat gain for your climate. Patio doors are mostly glass, so glass specs drive comfort and energy loss.
- Frame material
- Vinyl for value. Fiberglass for stability and paintability. Aluminum-clad wood for a wood interior. Aluminum only in mild climates unless thermally broken. Frame material sets maintenance, thermal performance and how well the door stays square.
- Rollers and track
- Prefer adjustable, replaceable tandem rollers and a track that drains water. Worn rollers and clogged tracks are the main reasons sliders become hard to open.
- Coastal or high-wind sites
- Check the design pressure (DP) and any impact or local code approvals the site requires. Standard units may not meet hurricane-zone code.
Brands that matter

What to avoid
- Non-thermally-broken aluminum frames in cold climates, which sweat and lose heat.

- Ordering by the old door's size instead of the rough opening.
