What aluminium sliding doors offer homes in Cobham
Most homeowners choosing aluminium sliding doors want the same things: more light, a clear view and a door that is easy to live with.
For a south- or west-facing garden in Cobham, solar-control glass in the sliding panels can keep a glazed room more comfortable on summer afternoons.
Thinking about a dark frame for a house in Cobham? Anthracite grey and black powder coats show off slim aluminium sightlines, and dual colour keeps the inside lighter if you prefer.
- 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.
- Because the panels slide rather than swing, nothing opens into the room or across the patio, leaving space for a dining table, sofa or planters right up to the glass.
- 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.
How much sun will a door in Cobham get?
At the latitude of Cobham, the midday sun climbs to about 62° in late June but only about 15° in late December, when daylight lasts around 7 h 51 min against 16 h 36 min in midsummer. A south-facing aluminium sliding door lets that low winter sun deep into the room; on a west or south elevation, solar-control glass keeps summer afternoons comfortable.

How fitting works in Cobham
We plan the job around your home in Cobham: survey first, then a written quote, then manufacture (typically 4–6 weeks from survey sign-off). The fitting itself usually takes 1 day for a two-panel straight swap; 1–2 days for larger doors. If you are in Surbiton or Woking, the same process and prices apply.
Do you need approval in Cobham?
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.
Finishes and extras 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.
- Glass. Double or triple glazed units in toughened or laminated safety glass, with solar-control or self-cleaning coatings.
- Panel configuration. Two, three or four panels, with the sliding panel on the left, right or both sides to suit how you use the room.
Questions about aluminium sliding doors in Cobham
Do I need building approval for aluminium sliding doors in Cobham?
In England a replacement door is a controlled fitting, so compliance is arranged through a competent person scheme installer or Building Control; new openings need a Building Regulations application. We confirm the right route for your property at survey, so the paperwork is in place before fitting.
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.
Are aluminium sliding doors warm enough for a UK home?
Thermally broken aluminium sliding doors are warm enough for most homes, with typical whole-door U-values around 1.2–1.6 W/m²K double glazed and 0.8–1.1 W/m²K triple glazed, depending on the system. In England, a new or replacement door in an existing home with more than 60% glazing must reach 1.4 W/m²K or better, so the glass is specified to meet that. Wales, Scotland and Northern Ireland have their own rules.
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.
