How Secure Are Your Windows And Doors?
Is Your Home As Safe As It Could Be From Intruders?

In 2024-2025 there were 166,577 home burglaries reported across England and Wales. That equates to a house being burgled every 189 seconds. Is your home equipped to keep you safe from intruders?
Here’s what you can do to improve the security of your home;
- Invest in laminated glazing.
- Replace door and window locks to have multipoint locking systems with 3 star rated cylinders.
- Replace PVCu door panels with aluminium reinforced PVCu panels.
- Consider investing in new windows or doors which are Secured by Design and consider a modern composite door, manufactured with extra reinforcement.
How does laminated glazing enhance security?
Laminated glass is made with a layer of vinyl plastic (a strong-binding resin) between the layers of glass which acts to hold the glass together even when shattered, similar to a car windscreen. Unlike toughened glass which breaks into lots of small pieces or tempered glass which breaks into shards, laminated glass gives extra strength and security with its ability to withstand impact, making it a lot more difficult for intruders to break through. Most existing windows and doors can be upgraded to have laminated double or triple glazed sealed units.
How is a multipoint locking system with a 3 star cylinder more secure?
A multipoint locking system has several locks along the edge of the door, ensuring high security and no vulnerable areas being left exposed. The 3 star rating indicates that the lock meets test standards and is considered safe and secure. Diamond secure 3 star cylinders ensure locks meet an even higher standard, preventing intruders ability to snap or drill the lock cylinder. Most locks can be upgraded in existing windows and doors.
How can the manufacturing of your door make a difference?
Composite doors specifically are often designed with strength in mind. Rockdoor composite doors have the option to be manufactured with a steel security mesh that cannot be cut through to ensure high security from break ins. Whilst Palladio composite doors are manufactured with an ultra strong monocoque structure resistant to impact. Apeer composite doors are also manufactured with an expanded mesh reinforcement within the core and a strong vertical steel bar, exceeding Police approved security standards.
PVCu doors can also have aluminium reinforcement within the PVCu panels for extra strength.
What is Secured by Design?
Secured by design is a Police governed accreditation scheme which ensures windows and doors meet specific security standards. All windows and doors which are approved by the Secured By Design (SBD) initiative, must meet PAS 24 standard which tests the overall strength and durability of a product. Manufacturers that are approved by SBD are inspected, tested and approved regularly to be secure against burglary.
