Timber and alu-clad sliding doors in Slough: what to know
Most homeowners choosing timber and alu-clad sliding doors want the same things: more light, a clear view and a door that is easy to live with.
Because timber and alu-clad sliding doors typically take 8–10 weeks to make, a Slough building programme runs more smoothly when the survey happens as soon as the opening size is fixed.
Where the back of a Slough 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.
- 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.
- 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.
How much sun will a door in Slough get?
At the latitude of Slough, the midday sun climbs to about 62° in late June but only about 15° in late December, when daylight lasts around 7 h 49 min against 16 h 38 min in midsummer. A south-facing timber and alu-clad sliding door lets that low winter sun deep into the room; on a west or south elevation, solar-control glass keeps summer afternoons comfortable.

Survey, manufacture and fitting around Slough
Once the opening is measured, nothing is ordered until you sign off the specification. Lead time is typically 8–10 weeks from survey sign-off. Our fitters protect floors, remove the old door, install and seal the new one and leave the area clean — usually 1 day for a two-panel swap; 1–2 days for larger doors for a door like this.
Do you need approval in Slough?
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.
Options to consider for your timber and alu-clad sliding door
- Timber species. Oak or another hardwood for a visible grain, or engineered softwood where a painted finish is planned.
- Interior finish. Clear lacquer, a wood stain or a painted colour, chosen to match floors, beams or kitchen units.
- 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 Slough
Do I need building approval for timber and alu-clad sliding doors in Slough?
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.
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.
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.
How often do timber sliding doors need treating?
Timber sliding doors need the outside re-coated every few years, depending on how exposed the elevation is and which finish system is used; doors facing full sun or coastal weather need attention soonest. Alu-clad doors avoid this, needing only an occasional wash outside. Inside, timber only needs wiping and an occasional refresh of the lacquer or oil, and a clean track protects the rollers.
