French Door

Paired hinged doors with broad glass area and traditional styling.

French doors are paired hinged doors with generous glass area and a traditional divided-lite or full-lite appearance. They can be used between interior rooms or as exterior patio doors, but exterior applications require careful coordination of swing direction, astragal sealing, threshold drainage, multi-point locking, screens, and wind-driven rain exposure.

Configurations

How It Comes

Inswing French Door

Panels swing into the room, protecting exterior hinges but requiring interior clearance.

Outswing French Door

Panels swing outward, improving interior furniture clearance and wind-pressure performance in some exposures.

Full-Lite French Door

Large glass area maximizes daylight and views.

Divided-Lite French Door

Simulated or true divided lites provide traditional proportions and privacy options.

Project Coordination

Details To Confirm Early

01

Confirm rough opening and load path

Large and heavy door systems depend on plumb jambs, a level sill, and headers that stay within deflection limits.

02

Coordinate threshold water management

Sill pans, drainage paths, exterior slope, and accessibility requirements must be resolved before ordering.

03

Verify hardware and screen clearances

Handles, locks, closers, shades, and screens can conflict with trim, furniture, or adjacent panels if not coordinated.

Product Questions

Common Questions

What should I compare first when selecting french door?

Start with the operation or glass makeup, then verify performance ratings, installation conditions, accessory compatibility, and warranty limits for the exact product series.

Can french door be used in any opening?

No. Size, exposure, code requirements, frame capacity, hardware, and installation details determine whether a product is appropriate for a specific opening.

What documents should I ask for before ordering?

Request product data, installation instructions, warranty terms, available test reports, and shop drawings for custom sizes, large assemblies, or code-sensitive conditions.
