Are large floor-to-ceiling sliding doors right for homes in County Londonderry?
A few practical points decide whether large floor-to-ceiling sliding doors suit a particular room and opening:
If your County Londonderry extension has a higher ceiling than the rest of the house, panels around 2.7 m high carry the glass right up and avoid a strip of wall above the door.
For a County Londonderry kitchen extension facing south or west, a whole wall of glass takes in sunshine all afternoon, so solar-control glass or integral blinds help keep it comfortable.
- Solar-control coatings can be added to tall south or west facing panels, reducing summer heat gain while still letting in plenty of daylight.
- Designing the door and steel together lets the engineer allow for panel weight and tight deflection limits, so the sliding gear runs true across the full span.
- A flush threshold with an outside drainage channel lets a large opening work as a level route between the kitchen floor and the terrace.

Questions about large floor-to-ceiling sliding doors in County Londonderry
How soon can you survey in County Londonderry?
Survey dates in County Londonderry are arranged individually when we reply to your enquiry. After you approve the written quote, manufacture is typically 6–8 weeks from survey sign-off.
How much do large floor-to-ceiling sliding doors cost?
Large floor-to-ceiling sliding doors start from a guide price of £7,995 for a 2.4 m two-panel door with 2.7 m high panels, fitted, inc VAT. A 4.8 m three-panel door at that height is a guide £12,595–£15,395, and an 8 m four-panel door is around £18,695. Structural work is priced separately, and the final price is fixed in a written quote after survey.
Do large sliding doors need a steel beam?
Large sliding doors usually need a steel beam or frame, because most are fitted into a new or widened structural opening. In England that is structural work needing a Building Regulations application and structural calculations, which are included in our guide price for forming the opening; in Scotland it needs a building warrant, and Wales and Northern Ireland have their own approval routes. The beam must be stiff enough not to deflect onto the door.
How long do large sliding doors take?
Large sliding doors typically take 6–8 weeks to make after survey sign-off, as most use slimline or lift and slide systems with large glass units. Forming the opening typically takes 3–5 days of building work, and fitting the door 1–2 days with a larger team and lifting equipment where needed. Each stage is a typical duration, and dates are agreed once you order.
