Timber and alu-clad sliding doors in Bromley: what to know
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 Bromley building programme runs more smoothly when the survey happens as soon as the opening size is fixed.
Where the back of a Bromley home faces south and takes full sun, choosing alu-clad keeps the timber protected and cuts out the re-coating that strong sunlight makes necessary.
- 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.
- 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.
- Wood is a natural insulator, so timber frames feel warm to the touch in winter and help keep condensation off the inside face of the frame.
Daylight in Bromley and what it means for your glass
In Bromley the shortest day has roughly 7 h 51 min of daylight and the longest about 16 h 37 min. The noon sun sits near 15° above the horizon in winter and 62° in summer — so glass that faces south collects useful warmth from October to March, while a west-facing door may need solar control to stop it overheating in July.

How fitting works in Bromley
We plan the job around your home in Bromley: survey first, then a written quote, then manufacture (typically 8–10 weeks from survey sign-off). The fitting itself usually takes 1 day for a two-panel swap; 1–2 days for larger doors. If you are in Beckenham or Chislehurst, the same process and prices apply.
Do you need approval in Bromley?
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.
Which options matter for timber and alu-clad sliding doors?
- Timber species. Oak or another hardwood for a visible grain, or engineered softwood where a painted finish is planned.
- Sliding hardware. Inline rollers on smaller doors, or lift and slide gear for larger and heavier panels.
- 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 Bromley
Is the price different in Bromley?
No. Guide prices for timber and alu-clad sliding doors are the same across mainland Britain, including Bromley. The fitted price depends on size, system, glass and finish, and any structural work, all fixed in your written quote after survey.
Can I fit timber sliding doors to a listed building or in a conservation area?
Timber sliding doors can suit listed buildings and conservation areas, but listed buildings and properties under an Article 4 direction may need consent before any door is changed, so check with your local planning authority first. In England, replacing doors on an ordinary house with similar-looking ones is usually permitted development. Wales, Scotland and Northern Ireland have their own planning rules.
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.
Are timber sliding doors secure?
Timber sliding doors are secure when built with multi-point locking, laminated glass and robust sections, because engineered timber gives the locking keeps a solid, dense fixing. Timber systems are available tested to PAS 24, the UK enhanced security test standard for doorsets. Internally beaded glass and a key-locking handle add further resistance to forced entry.
