Can a stable door be fitted in a standard doorway?

Yes, stable doors are manufactured to fit standard residential door apertures. If your existing doorway is a non-standard size, we measure and order to your exact dimensions at the survey stage.

Are stable doors as thermally efficient as standard doors?

When both halves are closed and bolted together, a stable door performs comparably to a standard door. The meeting rail between the two halves is fully draught-sealed. Composite stable doors in particular offer excellent thermal performance.

Can the top half be left open safely while children or pets are inside?

Yes, the bottom half locks independently, keeping children and pets safely inside while the top provides ventilation and light. This is one of the main practical advantages of a stable door for rear and garden access.

How Stable Doors Work

See the operating states before you choose finishes

The stable door page is led by how the door behaves day to day: shut and bolted, split for ventilation, fully open, and detailed for weathering and security.

Made to measure

Closed, split-open, fully open, and detailed for weathering

These are the core positions homeowners usually want to compare when choosing a stable door for kitchens, gardens, and family entrances.

Closed and bolted together

When both leaves are shut and locked together, the door behaves as a single secure entrance door with the weather seals and locking working across the full height.

Everyday closed-door security position
Top and bottom sections secured as one unit
Best thermal and weathering performance

Split opening for ventilation

The upper sash can open independently so you can bring in air and light while keeping pets or children inside behind the lower section.

Classic stable-door use case
Good for kitchens, utility rooms, and family back doors
Ventilation without fully opening the entrance

Full opening when both sashes disengage

Both halves can be opened fully when you want the doorway clear for access to the garden, bringing items through, or using the door like a standard rear entrance.

Creates a full clear opening
Useful for garden traffic and wider access
Upper and lower sections disengage cleanly

Locking and drip-bar detail

Security and weathering matter as much as the split opening itself, so the meeting rail, locking detail, and double drip bars are part of the product decision.

Stable doors are a practical and characterful door style where the top and bottom halves open independently. You can have the top half open for light and ventilation while the bottom stays closed to keep children or pets safely inside. Originally found on farmhouses and cottages, stable doors have become a popular choice for rear doors and garden access in all kinds of homes. CII Double Glazing supplies stable doors in UPVC and composite materials across Essex and the surrounding area, fitted by our own directly-employed installation team.
