Are secure sliding doors right for homes in Hampshire?
A few practical points decide whether secure sliding doors suit a particular room and opening:
Replacing an old slider in Hampshire that has its glass beads on the outside? That is a weakness a modern internally glazed door removes.
Whichever door you choose for your Hampshire home, pair it with good habits: lock the door, remove the key and keep side gates bolted.
- Specifying a tested door when you replace an old slider gives you a clear security standard to compare against, even though Approved Document Q only applies to new homes.
- Laminated glass has a tough interlayer that holds the pane together when struck, so even a cracked panel resists an attempt to break through.
- 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.

Approvals in England
English Building Regulations treat a new or replacement external door in an existing home as a controlled fitting: it needs a U-value of 1.4 W/m²K or better (or Doorset Energy Rating band C) if more than 60% of it is glazed (Approved Document L), and safety glass in a critical location (Approved Document K). Compliance is arranged through a competent person scheme installer or a Building Control notification, so you get a certificate for your records.
Questions about secure sliding doors in Hampshire
Can you match other doors and windows in my Hampshire 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.
What makes old sliding patio doors insecure?
Older sliding patio doors are often vulnerable because the sliding panel can be lifted off its track, the single-point lock can be forced, the glass beads are on the outside or the cylinder can be snapped. Modern secure sliding doors address each of those weaknesses with anti-lift devices, multipoint locks, internal glazing and anti-snap cylinders.
Does Approved Document Q apply to my replacement door?
No, Approved Document Q sets security requirements for doors and windows in new dwellings in England and does not apply when you replace a door in an existing home. Choosing a door tested to PAS 24 is still a sensible benchmark for a replacement, because it gives you a recognised standard rather than relying on how the hardware looks.
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.
