French Doors and Glazed Double Doors: Vision Glass, Security and Hardware Specification
How to specify glass type, muntin layout, security film and matching hardware for French doors and glazed double-door sets.
Quick answer
Specify French and glazed double doors by confirming the glass safety requirement, muntin layout, leaf and frame construction, active and inactive leaf, meeting detail, lock set and any closer or coordinator hardware before the door set is released.
French doors are a full door-set specification
French doors and glazed double doors are not only a leaf style. The project must identify the glazing, grid or muntin construction, meeting stiles, active leaf, locking arrangement, hinges, closer or sequencer hardware and the frame condition. These details affect both appearance and daily operation.
Glass and grid choices
| Detail | What to define | Why it matters |
|---|---|---|
| Glass type | Safety, privacy, acoustic or security requirement | The selected glass must suit the intended opening and use |
| Muntin layout | True divided construction, applied grid or approved visual pattern | Grid depth and shadow lines change the finished appearance |
| Double-door meeting | Active leaf, inactive leaf, astragal or meeting-stile detail | Hardware and closing sequence depend on the meeting arrangement |
| Hardware | Lock, flush bolts, hinges, closer and coordinator where needed | Double leaves must close and latch in the intended order |
Muntins, glass edges and visual consistency
Confirm whether the grid is a true divided construction, an applied decorative grid or another approved method. The project sample should show the glass edge, muntin proportion, paint or finish, and the view from both sides of the leaf so the installed result matches the desired style.
Double-door hardware and closing sequence
Where both leaves close into one opening, the active and inactive leaves must be clear in the schedule. If a closer or coordinator is required, confirm the hardware location and closing sequence with the selected frame, meeting detail and lock arrangement. Do not add these components after the leaf and frame preparation are fixed.
RFQ checklist for glazed double doors
- Leaf count, active leaf, inactive leaf and handing.
- Glass type, thickness or safety requirement and privacy direction.
- Muntin layout, panel count and finish reference.
- Frame, threshold, meeting-stile and astragal detail.
- Hinges, lock, flush bolts, closer and coordinator requirement.
- Opening size, quantity, packing protection and destination.

Buyer questions
Select the glass by the project’s safety, privacy, security, acoustic and location requirements, then confirm that choice in the approved door-set specification.
True divided construction separates glazing areas structurally, while applied grids create a visual division on the glass surface. The approved sample should make the chosen method clear.
A coordinator can control the closing order of paired leaves when the selected meeting detail or hardware requires one leaf to close before the other.
Not always. Active and inactive leaves, flush bolts, meeting details and any coordinator or closer can change the required hardware preparation.
Approve one complete door set showing the glass, muntin layout, finish, active leaf, meeting detail and hardware before releasing repeated production.
