Corner sliding doors across County Antrim
Here is what to weigh up if you are considering corner sliding doors for a home in County Antrim:
On any corner installation in County Antrim, the survey records floor and patio levels along both walls, because a terrace that falls differently on each side changes the threshold detail.
A County Antrim garden that sits to the side as well as the rear of the house is where a post-free corner earns its place, opening the room towards both.
- Because panels slide rather than fold, the corner can be opened on one side only, keeping the other side closed as a wind screen on cooler days.
- A corner of glass gives a much wider field of view than a single straight door, taking in more of the garden from a seat inside.
- Each elevation can have its own number of panels and its own sliding direction, letting the opening suit the shape of the garden and the furniture layout.

Daylight and glass in County Antrim
Sun angles matter for big glazed doors. Around County Antrim, midday sun reaches about 59° in summer and drops to about 12° 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.

Questions about corner sliding doors in County Antrim
Do I need building approval for corner sliding doors in County Antrim?
In Northern Ireland the Building Regulations (Northern Ireland) apply through district council building control; work there is by arrangement. We confirm the right route for your property at survey, so the paperwork is in place before fitting.
How long does a corner sliding door project take?
A corner sliding door typically takes 4–6 weeks to manufacture in standard aluminium and 6–8 weeks for slimline or lift and slide systems, from survey sign-off. The steelwork and building work usually take 3–5 days before the door goes in, and fitting the door takes 1–2 days. Engineer design and approvals come first, so the door is ordered once the steel is designed.
How do you maintain a corner sliding door?
Maintaining a corner sliding door is much like any aluminium slider, with extra attention to the corner: keep both tracks and the corner drainage clear, wipe the corner seals, and check the meeting panels still lock smoothly. Rollers can be adjusted if a panel drops. Because a new extension can settle slightly in its first year, the corner panels may need a small adjustment after that.
How big can a corner sliding door be?
A corner sliding door in our range typically covers about 3 m to 8 m of combined width across both walls, usually four panels up to about 4.8 m and six panels above that. The two sides do not need to be equal. Panel height starts at the standard 2.1 m and can go taller depending on the system, which is confirmed at survey alongside the structural design.
