French Doors
French doors are a pair of hinged glass doors that meet in the middle and open from the center, framing a wide, symmetrical opening to a patio or garden. Crateworks builds French doors in slim thermally-broken aluminum rather than timber, so the frame stays narrow and does not rot or warp, made to your opening for renovation and replacement projects.
Best for: A classic, symmetrical opening to outdoor space, where the look of a centered double door matters more than a fully cleared span.
French Doors spec into Maison Collection, and Farmhouse builds.

- What are French doors?
- French doors are a matched pair of hinged glass doors that open from the center, where the two panels meet. They give a wide, symmetrical opening and a traditional look. In aluminum, the frame and the central meeting stile stay slim, so the pair shows more glass than a timber equivalent.
- What is the difference between French doors and a sliding door?
- French doors swing open on hinges from the center, so they need swing clearance but give a classic, symmetrical look. A sliding door moves on a track and needs no swing space, but always keeps a panel across part of the opening. French doors suit a traditional facade; sliders suit a wide modern opening.
- Are aluminum French doors better than wood?
- Aluminum French doors keep a slimmer frame and meeting stile than wood, show more glass, and will not rot, warp, or need repainting. Wood has a warmth some buyers prefer. For a low-maintenance door that holds a narrow sightline, aluminum is the longer-lasting choice.
- Do these doors carry weather and structural certifications?
- We frame our exterior doors for renovation and replacement, and we only state a specific certification once the supplier has furnished the test documentation in writing. Requirements like water-tightness and wind-load vary by location. Tell us where the project is and we will confirm what we can document before you order.
