Why choose timber and alu-clad sliding doors in New Malden?
These are the points a surveyor will go through with you when you choose timber and alu-clad sliding doors for a home in New Malden:
If your New Malden home is a period property or a barn conversion, timber and alu-clad sliding doors can bring in more light without the modern look of a metal frame.
For a listed building or a house in a conservation area in New Malden, check with the local planning authority before choosing any new door; timber frames are often closer in character to the original joinery.
- A timber sliding door sits comfortably beside brick, stone, render or weatherboarding, which helps where a modern metal frame would look out of character.
- Many timber systems use lift and slide hardware, letting large, heavy panels glide easily and then settle onto compressed seals for a tight closure.
- 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.
Planning glass for the light in New Malden
Daylight in New Malden runs from about 7 h 51 min in December to 16 h 37 min in June, with the noon sun at roughly 15° and 62° respectively. Use that to choose your glass: standard low-E double glazing for north and east elevations, and consider solar-control or triple glazing for sunny south and west walls.

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.
Which options matter for timber and alu-clad sliding doors?
- Alu-cladding. A powder-coated aluminium outer shell in a standard or RAL colour, with timber left on show inside.
- Timber species. Oak or another hardwood for a visible grain, or engineered softwood where a painted finish is planned.
- Handles. Traditional or contemporary handles in bronze, black, satin chrome or brass-effect finishes.
Questions about timber and alu-clad sliding doors in New Malden
Is the price different in New Malden?
No. Guide prices for timber and alu-clad sliding doors are the same across mainland Britain, including New Malden. The fitted price depends on size, system, glass and finish, and any structural work, all fixed in your written quote after survey.
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.
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.
Are timber sliding doors energy efficient?
Timber sliding doors are energy efficient because wood insulates naturally, and engineered timber systems typically achieve whole-door U-values comparable with good thermally broken aluminium, depending on the glass. In England, a new or replacement door in an existing home with more than 60% glazing must reach 1.4 W/m²K or better, and the glazing is specified to meet that. Wales, Scotland and Northern Ireland set their own energy rules.
