Is a timber and alu-clad sliding door a good fit for your home in Grantham?
Most homeowners choosing timber and alu-clad sliding doors want the same things: more light, a clear view and a door that is easy to live with.
Because timber and alu-clad sliding doors typically take 8–10 weeks to make, a Grantham building programme runs more smoothly when the survey happens as soon as the opening size is fixed.
For a listed building or a house in a conservation area in Grantham, check with the local planning authority before choosing any new door; timber frames are often closer in character to the original joinery.
- 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.
- Scratches and dents on internal timber faces can usually be sanded and refinished locally, rather than needing a whole panel replaced.
- A timber sliding door sits comfortably beside brick, stone, render or weatherboarding, which helps where a modern metal frame would look out of character.
Light and sun in Grantham
Daylight in Grantham runs from about 7 h 35 min in December to 16 h 55 min in June, with the noon sun at roughly 14° and 61° 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.

How fitting works in Grantham
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.
Options to consider for your timber and alu-clad sliding door
- Timber species. Oak or another hardwood for a visible grain, or engineered softwood where a painted finish is planned.
- Interior finish. Clear lacquer, a wood stain or a painted colour, chosen to match floors, beams or kitchen units.
- 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 Grantham
How soon can you survey in Grantham?
Surveys in the NG31 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 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.
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.
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.
