Timber and alu-clad sliding doors in Marlow: what to know
Here is what to weigh up if you are considering timber and alu-clad sliding doors for a home in Marlow:
Where the back of a Marlow 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.
Oak floors, exposed beams or a timber kitchen in your Marlow home? Matching the inside finish of the door ties the new glazing into the room.
- 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.
- 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.
Light and sun in Marlow
Sun angles matter for big glazed doors. Around Marlow, midday sun reaches about 62° in summer and drops to about 15° 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.

What happens when you order timber and alu-clad sliding doors in Marlow?
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.
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.
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.
- Handles. Traditional or contemporary handles in bronze, black, satin chrome or brass-effect finishes.
- 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 Marlow
How soon can you survey in Marlow?
Surveys in the SL7 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.
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.
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.
