Are secure sliding doors right for homes in Berkshire?
These are the points a surveyor will go through with you when you choose secure sliding doors for a home in Berkshire:
For a new-build or conversion in Berkshire with a security condition attached, send us the specification before we quote so the right system is chosen from the start.
If your Berkshire home has a rear garden reached by a side gate or shared alley, the back door is the one to specify with PAS 24 testing and laminated 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.
- Anti-lift devices in the head of the frame stop a closed sliding panel being levered up and lifted off its track, which is a classic weakness of older sliders.
- 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.

Daylight and glass in Berkshire
Because Berkshire sees long summer days (about 16 h 37 min) and short winter ones (about 7 h 50 min), the elevation your door faces makes a real difference. With the midday sun at about 15° in winter, a south-facing door brings light well into the room; a west-facing door catches hot late-afternoon sun in summer.

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 Berkshire
Can you match other doors and windows in my Berkshire 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.
Are all your sliding doors PAS 24?
Not every door we supply is PAS 24 tested, and we would never claim otherwise. Our aluminium sliding doors are available in systems tested to PAS 24, and your written quote states the exact system and specification. If PAS 24 matters to you, tell us at enquiry and we will specify a tested system and configuration to suit your opening.
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.
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.
