What timber and alu-clad sliding doors offer homes in Hendon
A few practical points decide whether timber and alu-clad sliding doors suit a particular room and opening:
Where the back of a Hendon 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 Hendon 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.
- 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.
Sunlight, glass and orientation in Hendon
At the latitude of Hendon, 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 39 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.

How fitting works in Hendon
A surveyor visits your Hendon home to measure the structural opening, check levels and the lintel, and talk through glass and finish. Once you confirm the written specification, the door is made to measure — typically 8–10 weeks from survey sign-off — and fitting usually takes 1 day for a two-panel swap; 1–2 days for larger doors. We also cover Golders Green (3 km south-east) and Finchley (3 km north-east).
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.
- Alu-cladding. A powder-coated aluminium outer shell in a standard or RAL colour, with timber left on show inside.
- Sliding hardware. Inline rollers on smaller doors, or lift and slide gear for larger and heavier panels.
Questions about timber and alu-clad sliding doors in Hendon
How soon can you survey in Hendon?
Surveys in the NW4 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.
Are timber sliding doors secure?
Timber sliding doors are secure when built with multi-point locking, laminated glass and robust sections, because engineered timber gives the locking keeps a solid, dense fixing. Timber systems are available tested to PAS 24, the UK enhanced security test standard for doorsets. Internally beaded glass and a key-locking handle add further resistance to forced entry.
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.
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.
