Are secure sliding doors right for homes in Norfolk?
Most homeowners choosing secure sliding doors want the same things: more light, a clear view and a door that is easy to live with.
Leaving a Norfolk house empty during the working day? A key-lockable handle stops anyone turning it from inside through broken glass.
Replacing an old slider in Norfolk that has its glass beads on the outside? That is a weakness a modern internally glazed door removes.
- 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 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.
- 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.

Daylight and glass in Norfolk
In Norfolk the shortest day has roughly 7 h 37 min of daylight and the longest about 16 h 52 min. The noon sun sits near 14° above the horizon in winter and 61° 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.

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 Norfolk
Is the price different in Norfolk?
No. Guide prices for secure sliding doors are the same across mainland Britain, including Norfolk. The fitted price depends on size, system, glass and finish, and any structural work, all fixed in your written quote after survey.
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.
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.
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.
