Are timber and alu-clad sliding doors right for your St Austell home?
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.
Oak floors, exposed beams or a timber kitchen in your St Austell home? Matching the inside finish of the door ties the new glazing into the room.
For a listed building or a house in a conservation area in St Austell, check with the local planning authority before choosing any new door; timber frames are often closer in character to the original joinery.
- Many timber systems use lift and slide hardware, letting large, heavy panels glide easily and then settle onto compressed seals for a tight closure.
- 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.
- A timber sliding door sits comfortably beside brick, stone, render or weatherboarding, which helps where a modern metal frame would look out of character.
How much sun will a door in St Austell get?
The midday sun over St Austell ranges from about 16° at the winter solstice to about 63° at midsummer. Low-angle winter light reaches further into a room through a tall door, which is one reason taller panels are worth considering; on south or west walls, pair them with solar-control glass.

How fitting works in St Austell
A surveyor visits your St Austell home to measure the structural opening, check levels and the lintel, and talk through glass and finish. Once you confirm the written specification, the door is made to measure — typically 8–10 weeks from survey sign-off — and fitting usually takes 1 day for a two-panel swap; 1–2 days for larger doors. We also cover Bodmin (15 km north) and Wadebridge (20 km north).
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.
Choosing the specification
- Sliding hardware. Inline rollers on smaller doors, or lift and slide gear for larger and heavier panels.
- Glass. Double or triple glazed safety glass, with slim glazing bars available for a period look.
- 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 St Austell
Can you match other doors and windows in my St Austell 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.
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 long do timber sliding doors take to make?
Timber and alu-clad sliding doors typically take 8–10 weeks to make after survey sign-off, longer than metal or uPVC, because each door is joinery-made, factory finished and allowed to cure before delivery. Fitting typically takes 1 day for a two-panel swap and 1–2 days for larger doors. These are typical timescales, confirmed once your order is placed.
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.
