Why choose timber and alu-clad sliding doors in Derby?
A few practical points decide whether timber and alu-clad sliding doors suit a particular room and opening:
For a listed building or a house in a conservation area in Derby, check with the local planning authority before choosing any new door; timber frames are often closer in character to the original joinery.
Where the back of a Derby 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.
- 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.
- 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.
- A timber sliding door sits comfortably beside brick, stone, render or weatherboarding, which helps where a modern metal frame would look out of character.
Planning glass for the light in Derby
In Derby the shortest day has roughly 7 h 34 min of daylight and the longest about 16 h 55 min. The noon sun sits near 14° above the horizon in winter and 61° 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.

What happens when you order timber and alu-clad sliding doors in Derby?
We plan the job around your home in Derby: 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 Belper or Ilkeston, the same process and prices apply.
Do you need approval in Derby?
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.
Finishes and extras for timber and alu-clad sliding doors
- 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.
- Interior finish. Clear lacquer, a wood stain or a painted colour, chosen to match floors, beams or kitchen units.
Questions about timber and alu-clad sliding doors in Derby
Can you match other doors and windows in my Derby home?
Usually, yes. Most aluminium and uPVC systems come in standard RAL colours and finishes, and we can quote dual colour where the inside and outside need to differ. Bring photos of existing frames to the 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 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.
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.
