Are timber and alu-clad sliding doors right for your Biggleswade home?
Here is what to weigh up if you are considering timber and alu-clad sliding doors for a home in Biggleswade:
Whether you live in Biggleswade or elsewhere in Bedfordshire, an exposed coastal or hilltop elevation makes a strong case for alu-clad rather than all-timber outside.
For a listed building or a house in a conservation area in Biggleswade, check with the local planning authority before choosing any new door; timber frames are often closer in character to the original joinery.
- 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.
- 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.
Light and sun in Biggleswade
Sun angles matter for big glazed doors. Around Biggleswade, midday sun reaches about 61° in summer and drops to about 14° in winter. That low winter sun is free heat through south-facing glass; high summer sun is easier to shade with a roof overhang, and solar-control glass helps where there is none.

Do you need approval in Biggleswade?
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.

Questions about timber and alu-clad sliding doors in Biggleswade
Do I need building approval for timber and alu-clad sliding doors in Biggleswade?
In England a replacement door is a controlled fitting, so compliance is arranged through a competent person scheme installer or Building Control; new openings need a Building Regulations application. We confirm the right route for your property at survey, so the paperwork is in place before fitting.
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.
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.
