Secure sliding doors (PAS 24) across County Durham
Most homeowners choosing secure sliding doors want the same things: more light, a clear view and a door that is easy to live with.
Whichever door you choose for your County Durham home, pair it with good habits: lock the door, remove the key and keep side gates bolted.
If your County Durham 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 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.
- Internally glazed or secured beads mean the glass cannot be removed from the outside, closing off a route that some older doors left open.
- 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 County Durham
In County Durham the shortest day has roughly 7 h 14 min of daylight and the longest about 17 h 18 min. The noon sun sits near 12° above the horizon in winter and 59° 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
In England, a replacement sliding door is a controlled fitting under the Building Regulations. In an existing home, a door with more than 60% glazing must reach a U-value of 1.4 W/m²K or better (or a Doorset Energy Rating of band C) under Approved Document L, and glass in doors must be safety glazing under Approved Document K. We arrange compliance through a competent person scheme installer or by notifying Building Control, and you receive the certificate.
Questions about secure sliding doors in County Durham

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.
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.
Is laminated glass worth it on a sliding door?
Laminated glass is worth considering on ground-floor doors that are hidden from the street, because it stays in one piece when cracked and slows anyone trying to break through. It also reduces some outside noise and filters most UV light. Toughened glass is still a safety glass but shatters into small pieces when broken.
