Why choose timber and alu-clad sliding doors in Beckenham?
A few practical points decide whether timber and alu-clad sliding doors suit a particular room and opening:
Because timber and alu-clad sliding doors typically take 8–10 weeks to make, a Beckenham building programme runs more smoothly when the survey happens as soon as the opening size is fixed.
Oak floors, exposed beams or a timber kitchen in your Beckenham home? Matching the inside finish of the door ties the new glazing into the room.
- 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.
- Many timber systems use lift and slide hardware, letting large, heavy panels glide easily and then settle onto compressed seals for a tight closure.
- Engineered timber is laminated from several layers with the grain opposed, so frames resist the twisting and warping that solid timber can suffer as the seasons change.
Light and sun in Beckenham
Daylight in Beckenham runs from about 7 h 50 min in December to 16 h 37 min in June, with the noon sun at roughly 15° and 62° respectively.

Survey, manufacture and fitting around Beckenham
Surveys in the BR3 district are booked at a time that suits you. After you approve the quote, manufacture is typically 8–10 weeks from survey sign-off; on fitting day the old door comes out, the new frame is set level and sealed, and the panels are adjusted so they glide properly. Fitting usually takes 1 day for a two-panel swap; 1–2 days for larger doors.
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.
Which options matter for timber and alu-clad sliding doors?
- 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.
- Sliding hardware. Inline rollers on smaller doors, or lift and slide gear for larger and heavier panels.
Questions about timber and alu-clad sliding doors in Beckenham
How soon can you survey in Beckenham?
Surveys in the BR3 district are booked at a time that suits you, and we offer survey dates when we reply to your enquiry. After you approve the written quote, manufacture is typically 8–10 weeks from survey sign-off.
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.
