Are timber and alu-clad sliding doors right for your Thornbury home?
Before you settle on a door type, it helps to know what timber and alu-clad sliding doors do well and what to check before you order.
Because timber and alu-clad sliding doors typically take 8–10 weeks to make, a Thornbury building programme runs more smoothly when the survey happens as soon as the opening size is fixed.
If your Thornbury home is a period property or a barn conversion, timber and alu-clad sliding doors can bring in more light without the modern look of a metal frame.
- A timber sliding door sits comfortably beside brick, stone, render or weatherboarding, which helps where a modern metal frame would look out of character.
- An alu-clad exterior shields the wood from rain and sunlight, so the outside needs only washing while the inside keeps a natural timber finish.
- The inside face can be finished to match existing oak floors, stair parts or window boards, so the new door feels part of the room rather than an addition.
Planning glass for the light in Thornbury
Because Thornbury sees long summer days (about 16 h 40 min) and short winter ones (about 7 h 48 min), the elevation your door faces makes a real difference. With the midday sun at about 15° in winter, a south-facing door brings light well into the room; a west-facing door catches hot late-afternoon sun in summer.

Rules for timber and alu-clad sliding doors in England
In England, a replacement sliding door is a controlled fitting under the Building Regulations. In an existing home, a door with more than 60% glazing must reach a U-value of 1.4 W/m²K or better (or a Doorset Energy Rating of band C) under Approved Document L, and glass in doors must be safety glazing under Approved Document K. We arrange compliance through a competent person scheme installer or by notifying Building Control, and you receive the certificate.
Options to consider for your timber and alu-clad sliding door

- Alu-cladding. A powder-coated aluminium outer shell in a standard or RAL colour, with timber left on show inside.
- Glass. Double or triple glazed safety glass, with slim glazing bars available for a period look.
Questions about timber and alu-clad sliding doors in Thornbury
Is the price different in Thornbury?
No. Guide prices for timber and alu-clad sliding doors are the same across mainland Britain, including Thornbury. The fitted price depends on size, system, glass and finish, and any structural work, all fixed in your written quote after survey.
How much do timber sliding doors cost?
Timber and alu-clad sliding doors start from a guide price of £5,095 for a 1.5 m two-panel door, fitted, inc VAT, at standard 2.1 m height. A 2.4 m door is a guide £6,495–£7,995, and a 4.8 m four-panel door is around £10,395. Species, cladding, finish and glass all affect the figure, and the final price is fixed in a written quote after survey.
How long do timber sliding doors take to make?
Timber and alu-clad sliding doors typically take 8–10 weeks to make after survey sign-off, longer than metal or uPVC, because each door is joinery-made, factory finished and allowed to cure before delivery. Fitting typically takes 1 day for a two-panel swap and 1–2 days for larger doors. These are typical timescales, confirmed once your order is placed.
What is the difference between timber and alu-clad sliding doors?
The difference is the outside face: a timber sliding door is wood inside and out, while an alu-clad door has a powder-coated aluminium shell fixed over the exterior timber. Alu-clad needs only washing outside and comes in any RAL colour; all-timber needs periodic re-coating but keeps a natural wood look on both faces. The inside is timber either way.
