What aluminium sliding doors offer homes in Caerphilly
The right door depends on the opening, the room and the way you use the garden. Here is how aluminium sliding doors tend to work out in practice:
If your Caerphilly 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 Caerphilly, solar-control glass in the sliding panels can keep a glazed room more comfortable on summer afternoons.
- 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.
- 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 Caerphilly get?
Daylight in Caerphilly runs from about 7 h 49 min in December to 16 h 39 min in June, with the noon sun at roughly 15° and 62° respectively. Use that to choose your glass: standard low-E double glazing for north and east elevations, and consider solar-control or triple glazing for sunny south and west walls.

How fitting works in Caerphilly
Once the opening is measured, nothing is ordered until you sign off the specification. Lead time is typically 4–6 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 straight swap; 1–2 days for larger doors for a door like this.
Do you need approval in Caerphilly?
Wales sets its own Building Regulations guidance, including Approved Document L (Wales) for energy. A replacement sliding door must meet those requirements and use safety glass, and we arrange compliance through a registered installer or the local Building Control service.
Choosing the specification
- Threshold. A standard or low threshold, or a flush finish with a drainage channel outside where floor levels allow.
- Dual colour. A different colour inside and outside, so the exterior can match your windows while the interior suits the room.
- 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 Caerphilly
How soon can you survey in Caerphilly?
Surveys in the CF83 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.
