Secure sliding doors (PAS 24) across County Down
Most homeowners choosing secure sliding doors want the same things: more light, a clear view and a door that is easy to live with.
For a new-build or conversion in County Down with a security condition attached, send us the specification before we quote so the right system is chosen from the start.
Leaving a County Down house empty during the working day? A key-lockable handle stops anyone turning it from inside through broken glass.
- A multipoint lock throws several hooks or bolts into the frame when the handle is locked, spreading the load so the panel cannot be forced at a single point.
- Robust interlocks where the panels meet reduce the chance of the door being levered open at the overlap, which is where a sliding door is often probed first.
- A doorset tested to PAS 24 has resisted a defined set of timed attacks using hand tools, giving an objective benchmark rather than a claim based on the look of the hardware.

Daylight and glass in County Down
Sun angles matter for big glazed doors. Around County Down, 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 secure sliding doors in County Down
Is the price different in County Down?
The door price is the same as anywhere else. Because County Down is covered by arrangement, any travel cost for delivery and fitting is shown in your quote before you order; the survey itself is free.
How do anti-lift devices work on a sliding door?
Anti-lift devices are blocks or bolts fitted in the head of the frame or on the sliding panel that fill the gap above the panel when the door is closed. Without them, some older sliding panels could be lifted up and out of the bottom track. With them, the panel cannot be raised far enough to clear the track.
Can I upgrade the locks on my existing sliding door?
Sometimes, but upgrading locks alone does not turn an old door into a tested one. A new anti-snap cylinder or a secondary bolt can improve security on a sound door, and our sliding door repairs page covers lock work. If the panel can be lifted out or the glass removed from outside, replacement is usually the better answer.
What is PAS 24?
PAS 24 is the UK enhanced security test standard for doorsets, including sliding doors. A door tested to it has been subjected to timed manual attacks with hand tools, mechanical loading of the panels and locks, and tests on how the glass is held. It applies to the complete doorset as tested, not to individual handles or locks on their own.
