Why choose aluminium sliding doors in Dunstable?
Here is what to weigh up if you are considering aluminium sliding doors for a home in Dunstable:
Before aluminium sliding doors are ordered for a Dunstable home, the survey should check the opening width, floor levels and existing lintel, so the quote reflects the real job.
Where a Dunstable property already has aluminium windows, matching the door colour and frame profile keeps the back of the house looking consistent.
- 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.
- A polyamide thermal break inside every profile separates the cold outer metal from the warm inner face, cutting heat loss and reducing the risk of condensation forming on the frame.
- 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.
How much sun will a door in Dunstable get?
Sun angles matter for big glazed doors. Around Dunstable, midday sun reaches about 62° in summer and drops to about 15° 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.

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.
Which options matter for aluminium sliding doors?
- Dual colour. A different colour inside and outside, so the exterior can match your windows while the interior suits the room.
- Handles and locks. Slim pull handles or lever handles in matching or contrasting finishes, with an enhanced security locking pack available.
- Colours. Standard shades such as anthracite grey, black and white, or a special RAL colour for an extra charge.
Questions about aluminium sliding doors in Dunstable
How soon can you survey in Dunstable?
Surveys in the LU6 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.
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.
How wide can an aluminium sliding door be?
An aluminium sliding door in our range can span from about 1.5 m to 6 m, split into two to four panels. Each panel is usually up to about 2.5–3 m wide depending on the system and the weight of the glass. Wider openings take more panels, and beyond about 6 m a multi-track or lift and slide system is usually the more practical choice.
