Secure sliding doors (PAS 24) across Devon
Before you settle on a door type, it helps to know what secure sliding doors do well and what to check before you order.
Ask your insurer whether a tested door or particular locks are a requirement on your Devon policy, so the quote can be specified to suit.
If your Devon 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.
- 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.
- 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 Devon
Sun angles matter for big glazed doors. Around Devon, midday sun reaches about 63° in summer and drops to about 16° 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.

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 Devon
Can you match other doors and windows in my Devon 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.
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.
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 is Secured by Design?
Secured by Design is a police-backed initiative that sets security standards for homes and products, and its requirements for doors build on PAS 24. Products and developments can gain recognition under the scheme. We are not a Secured by Design member company; if a project specifies it, tell us at the start so we can check what the specification requires.
