Are timber and alu-clad sliding doors right for your Alton home?
A few practical points decide whether timber and alu-clad sliding doors suit a particular room and opening:
Oak floors, exposed beams or a timber kitchen in your Alton home? Matching the inside finish of the door ties the new glazing into the room.
Whether you live in Alton or elsewhere in Hampshire, an exposed coastal or hilltop elevation makes a strong case for alu-clad rather than all-timber outside.
- A timber sliding door sits comfortably beside brick, stone, render or weatherboarding, which helps where a modern metal frame would look out of character.
- 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.
- 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.
How much sun will a door in Alton get?
At the latitude of Alton, the midday sun climbs to about 62° in late June but only about 15° in late December, when daylight lasts around 7 h 53 min against 16 h 34 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.

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.

Questions about timber and alu-clad sliding doors in Alton
Is the price different in Alton?
No. Guide prices for timber and alu-clad sliding doors are the same across mainland Britain, including Alton. The fitted price depends on size, system, glass and finish, and any structural work, all fixed in your 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.
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.
