Why choose timber and alu-clad sliding doors in Belfast?
Here is what to weigh up if you are considering timber and alu-clad sliding doors for a home in Belfast:
Whether you live in Belfast or elsewhere in County Antrim, an exposed coastal or hilltop elevation makes a strong case for alu-clad rather than all-timber outside.
Where the back of a Belfast 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.
- 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.
- Many timber systems use lift and slide hardware, letting large, heavy panels glide easily and then settle onto compressed seals for a tight closure.
- A timber sliding door sits comfortably beside brick, stone, render or weatherboarding, which helps where a modern metal frame would look out of character.
Sunlight, glass and orientation in Belfast
Daylight in Belfast runs from about 7 h 15 min in December to 17 h 17 min in June, with the noon sun at roughly 12° and 59° 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 much do timber and alu-clad sliding doors cost in Belfast?

What happens when you order timber and alu-clad sliding doors in Belfast?
Surveys in the BT1 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. Belfast is in an area we cover by arrangement: the survey is still free, and survey dates, delivery and any travel cost for delivery and fitting are confirmed in your quote before you order.

In Northern Ireland, the Building Regulations (Northern Ireland) apply through your district council's building control service, with energy guidance in Technical Booklet F1. Work in Northern Ireland is by arrangement, and we confirm the approval route for your property at survey.

Questions about timber and alu-clad sliding doors in Belfast
Do you fit timber and alu-clad sliding doors in Belfast?
Yes, by arrangement. Belfast is in an area we cover by arrangement: the survey is still free, and survey dates, delivery and any travel cost for delivery and fitting are confirmed in your quote before you order.
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.
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.
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.
