Are aluminium sliding doors right for your Dorchester home?
A few practical points decide whether aluminium sliding doors suit a particular room and opening:
If your Dorchester home has a rear extension or kitchen-diner, aluminium sliding doors let you place a table close to the glass, because no panel swings into the room.
For a south- or west-facing garden in Dorchester, solar-control glass in the sliding panels can keep a glazed room more comfortable on summer afternoons.
- Polyester powder coating is baked onto the aluminium in the factory, giving a hard, even colour that resists fading and chalking and does not need repainting in normal use.
- Multi-point hook locks grip the frame at several points along the closing edge, while anti-lift blocks stop a shut panel being raised off its track from outside.
- Narrow aluminium frames and meeting stiles put more of the opening into glass, so you see more garden and less frame than with a uPVC door of the same size.
Sunlight, glass and orientation in Dorchester
In Dorchester the shortest day has roughly 7 h 57 min of daylight and the longest about 16 h 30 min. The noon sun sits near 16° above the horizon in winter and 63° 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.

Survey, manufacture and fitting around Dorchester
A surveyor visits your Dorchester 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 4–6 weeks from survey sign-off — and fitting usually takes 1 day for a two-panel straight swap; 1–2 days for larger doors. We also cover Weymouth (12 km south) and Wareham (23 km east).
Rules for aluminium 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 aluminium sliding door
- Glass. Double or triple glazed units in toughened or laminated safety glass, with solar-control or self-cleaning coatings.
- Threshold. A standard or low threshold, or a flush finish with a drainage channel outside where floor levels allow.
- Handles and locks. Slim pull handles or lever handles in matching or contrasting finishes, with an enhanced security locking pack available.
Questions about aluminium sliding doors in Dorchester
How soon can you survey in Dorchester?
Surveys in the DT1 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 4–6 weeks from survey sign-off.
Should I choose aluminium sliding doors or bifolds?
Choose aluminium sliding doors if you want the most glass and fewest frames when the door is closed, and bifolds if you want almost the whole width open in summer. A slider keeps wide panels with slim meeting stiles but only opens part of the width; a bifold folds away but shows a frame every metre or so. Our sliding doors vs bifold doors guide compares them in detail.
Are aluminium sliding doors secure?
Aluminium sliding doors can be very secure when they combine multi-point hook locks, anti-lift blocks and laminated glass. Systems are available tested to PAS 24, the UK enhanced security standard for doorsets, and an enhanced security locking pack can be added to your quote. Most systems are glazed from the inside, so the glass cannot be unclipped from outside.
How much do aluminium sliding doors cost?
Aluminium sliding doors start from a guide price of £3,295 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 £4,295–£5,295, and a 4.8 m four-panel door is around £6,995. Glass, colour and threshold choices move the price within the range, and the final figure is fixed in a written quote after survey.
