Is a timber and alu-clad sliding door a good fit for your home in Derry/Londonderry?
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.
Whether you live in Derry/Londonderry or elsewhere in County Londonderry, an exposed coastal or hilltop elevation makes a strong case for alu-clad rather than all-timber outside.
Where the back of a Derry/Londonderry 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.
- 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.
- A timber sliding door sits comfortably beside brick, stone, render or weatherboarding, which helps where a modern metal frame would look out of character.
- 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.
Light and sun in Derry/Londonderry
Sun angles matter for big glazed doors. Around Derry/Londonderry, midday sun reaches about 58° in summer and drops to about 12° in winter. That low winter sun is free heat through south-facing glass; high summer sun is easier to shade with a roof overhang, and solar-control glass helps where there is none.

Questions about timber and alu-clad sliding doors in Derry/Londonderry
Can you match other doors and windows in my Derry/Londonderry home?
Usually, yes. Most aluminium and uPVC systems come in standard RAL colours and finishes, and we can quote dual colour where the inside and outside need to differ. Bring photos of existing frames to the 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.
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.
