Are timber and alu-clad sliding doors right for your Twickenham home?
The right door depends on the opening, the room and the way you use the garden. Here is how timber and alu-clad sliding doors tend to work out in practice:
Whether you live in Twickenham or elsewhere in Greater London, an exposed coastal or hilltop elevation makes a strong case for alu-clad rather than all-timber outside.
If your Twickenham 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.
- 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.
- Scratches and dents on internal timber faces can usually be sanded and refinished locally, rather than needing a whole panel replaced.
- An alu-clad exterior shields the wood from rain and sunlight, so the outside needs only washing while the inside keeps a natural timber finish.
Daylight in Twickenham and what it means for your glass
In Twickenham the shortest day has roughly 7 h 50 min of daylight and the longest about 16 h 38 min. The noon sun sits near 15° above the horizon in winter and 62° in summer — so glass that faces south collects useful warmth from October to March, while a west-facing door may need solar control to stop it overheating in July.

From survey to fitted door in Twickenham
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
In England, a replacement sliding door is a controlled fitting under the Building Regulations. In an existing home, a door with more than 60% glazing must reach a U-value of 1.4 W/m²K or better (or a Doorset Energy Rating of band C) under Approved Document L, and glass in doors must be safety glazing under Approved Document K. We arrange compliance through a competent person scheme installer or by notifying Building Control, and you receive the certificate.
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.
- Alu-cladding. A powder-coated aluminium outer shell in a standard or RAL colour, with timber left on show inside.
- Interior finish. Clear lacquer, a wood stain or a painted colour, chosen to match floors, beams or kitchen units.
Questions about timber and alu-clad sliding doors in Twickenham
Can you match other doors and windows in my Twickenham 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 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.
