Are aluminium sliding doors right for homes in County Londonderry?
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:
Thinking about a dark frame for a house in County Londonderry? Anthracite grey and black powder coats show off slim aluminium sightlines, and dual colour keeps the inside lighter if you prefer.
Where a County Londonderry property already has aluminium windows, matching the door colour and frame profile keeps the back of the house looking consistent.
- Aluminium is stiff enough to carry wide panels without bowing, which keeps the number of vertical frames low even across openings of four, five or six metres.
- 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.

A 2.4 m door is a guide £4,295–£5,295, and a 4.8 m four-panel door is around £6,995.

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.
