Is a timber and alu-clad sliding door a good fit for your home in Farnham?
The right door depends on the opening, the room and the way you use the garden. Here is how timber and alu-clad sliding doors tend to work out in practice:
Oak floors, exposed beams or a timber kitchen in your Farnham home? Matching the inside finish of the door ties the new glazing into the room.
Whether you live in Farnham or elsewhere in Surrey, an exposed coastal or hilltop elevation makes a strong case for alu-clad rather than all-timber outside.
- 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.
- 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.
- A timber sliding door sits comfortably beside brick, stone, render or weatherboarding, which helps where a modern metal frame would look out of character.
How much sun will a door in Farnham get?
Sun angles matter for big glazed doors. Around Farnham, 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 Farnham?
Surveys in the GU9 district are booked at a time that suits you. After you approve the quote, manufacture is typically 8–10 weeks from survey sign-off; on fitting day the old door comes out, the new frame is set level and sealed, and the panels are adjusted so they glide properly. Fitting usually takes 1 day for a two-panel swap; 1–2 days for larger doors.
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
- Glass. Double or triple glazed safety glass, with slim glazing bars available for a period look.
- 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 Farnham

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.
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.
