Are timber and alu-clad sliding doors right for your Chislehurst home?
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 Chislehurst building programme runs more smoothly when the survey happens as soon as the opening size is fixed.
If your Chislehurst 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.
- 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.
- Stains, paints and lacquers are sprayed in the factory under controlled conditions, giving a more even and longer-lasting coat than a finish brushed on site.
- 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.
Light and sun in Chislehurst
Daylight in Chislehurst 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. Use that to choose your glass: standard low-E double glazing for north and east elevations, and consider solar-control or triple glazing for sunny south and west walls.
Guide prices for timber and alu-clad sliding doors in Chislehurst

Survey, manufacture and fitting around Chislehurst
Here is the usual sequence in Chislehurst: guide price, free survey, written quote, then manufacture (typically 8–10 weeks from survey sign-off). Fitting typically takes 1 day for a two-panel swap; 1–2 days for larger doors. Nearby, we also survey in Sidcup, Bromley and Eltham.
Rules for timber and alu-clad sliding doors in England
English Building Regulations treat a new or replacement external door in an existing home as a controlled fitting: it needs a U-value of 1.4 W/m²K or better (or Doorset Energy Rating band C) if more than 60% of it is glazed (Approved Document L), and safety glass in a critical location (Approved Document K). Compliance is arranged through a competent person scheme installer or a Building Control notification, so you get a certificate for your records.
Options to consider for your timber and alu-clad sliding door
- Handles. Traditional or contemporary handles in bronze, black, satin chrome or brass-effect finishes.
- Sliding hardware. Inline rollers on smaller doors, or lift and slide gear for larger and heavier panels.
- Alu-cladding. A powder-coated aluminium outer shell in a standard or RAL colour, with timber left on show inside.
Questions about timber and alu-clad sliding doors in Chislehurst
How soon can you survey in Chislehurst?
Surveys in the BR7 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.
Are timber sliding doors energy efficient?
Timber sliding doors are energy efficient because wood insulates naturally, and engineered timber systems typically achieve whole-door U-values comparable with good thermally broken aluminium, depending on the glass. In England, a new or replacement door in an existing home with more than 60% glazing must reach 1.4 W/m²K or better, and the glazing is specified to meet that. Wales, Scotland and Northern Ireland set their own energy rules.
How big can a timber sliding door be?
A timber sliding door in our range is typically about 1.5 m to 4.8 m wide overall, in two to four panels, at standard 2.1 m height or taller on request. Individual panel sizes depend on the system and glass weight; larger panels usually move to lift and slide hardware so they stay easy to open. Sizes are confirmed after survey.
