Are external pocket sliding doors right for your Larne home?
Before you settle on a door type, it helps to know what external pocket sliding doors do well and what to check before you order.
However sheltered or exposed your Larne home is, external pocket sliding doors need a drained pocket and a clear external channel so rainwater running along the track never sits inside the wall.
If the wall beside your Larne patio opening is free of windows, radiators and sockets, it may be long enough to take a pocket so the panels disappear completely.
- With every panel slid into the wall, the full width of the opening is clear, so the room and terrace join without a fixed panel in the way.
- When closed, a pocket door looks like a large-paned slider, with slim meeting stiles and plenty of glass instead of the many frames of a folding door.
- Open panels are hidden inside the wall rather than stacked in view, keeping the opening clean-lined compared with a bifold stack at one side.
Light and sun in Larne
In Larne the shortest day has roughly 7 h 12 min of daylight and the longest about 17 h 20 min. The noon sun sits near 12° above the horizon in winter and 59° in summer — so glass that faces south collects useful warmth from October to March, while a west-facing door may need solar control to stop it overheating in July.

How fitting works in Larne
A surveyor visits your Larne home to check the wall, the structure above and the floor levels, and talks through glass and finish. Any building work is planned to the engineer's design, the door is made to the finished opening sizes — typically 6–8 weeks from survey sign-off — and fitting usually takes 3–5 days of building work to form the opening and pocket, then 1–2 days to fit the door. Larne is in an area we cover by arrangement: the survey is still free, and survey dates, delivery and any travel cost for delivery and fitting are confirmed in your quote before you order.
Rules for external pocket sliding doors in Northern Ireland
Opening up a wall in Northern Ireland needs district council building control approval and structural calculations. We take on this work in Northern Ireland by arrangement.
Options to consider for your external pocket sliding door
- Glass. Double or triple glazed safety glass, with laminated or solar-control units as needed.
- Internal finish. Plastered, panelled or tiled finishes on the pocket wall, with the access panel set discreetly into it.
- System type. Standard aluminium, slimline or lift and slide pocket systems, chosen to suit panel weight and sightlines.
Questions about external pocket sliding doors in Larne
Can you match other doors and windows in my Larne home?
Usually, yes. Most aluminium and uPVC systems come in standard RAL colours and finishes, and we can quote dual colour where the inside and outside need to differ. Bring photos of existing frames to the survey.
How do you maintain rollers inside a wall pocket?
You maintain pocket door rollers through the access panel built into the inside of the pocket wall, which lets the track be vacuumed and the rollers adjusted without opening up the wall. Keep the outside drainage channel clear so water cannot back up into the pocket, and run the panels fully in and out now and then. If a panel starts to rub inside the pocket, a small roller height adjustment through the access panel usually cures it.
How long does an external pocket door project take?
An external pocket door typically takes 6–8 weeks to make after survey sign-off, and the building work to form the opening and pocket typically takes 3–5 days before the door goes in. Fitting the door then takes 1–2 days. Engineer design and Building Regulations approval come first, so the whole project runs longer than a straight door swap.
How much wall do I need for an external pocket door?
An external pocket door needs a clear length of wall beside the opening at least as long as the panels that slide into it, plus a little for the frame. For a single 2 m panel that means just over 2 m of wall with no windows, radiators, sockets or pipes in it. A two-sided pocket splits the panels between both sides, so each side needs less length.
