Keeping you Secure - Police Preferred Standards

Secured by Design (SBD) is the official UK Police flagship initiative supporting the principles of ‘designing out crime’. Endurance doors hold the Secured by Design License and their Composite doorset range has been designed, tested and achieved the standard when combined with laminated glass.

This collection of composite doors has been designed, tested and assessed to ensure they meet SBD requirements. This means that they have been tested to PAS 24 2016 and have shown complete compliance. We understand the importance of feeling safe in your home, which is why we only offer you the most secured designs.

Intense Testing

The testing process is intense and comprehensive, comprising:

  • A manual attack on the locking hardware with tools including a crowbar and mole grips.
  • An unlimited number of 3-minute attacks on the door cylinder using a range of tools such as craft knives and screwdrivers.
  • 3-minute manual attack using chisels and brick bolsters to gain entry through the door.
  • Hard body impact test – impacts are applied to the door leaf at hinge points and locking points using a 50kg steel impactor.

Solid Timber Core

Our composite doors are renowned for their strength and security, our 48mm thick cross-bonded veneered laminated solid timber core delivers unrivalled strength and dimensional stability and is a natural choice for high security, providing our homeowners peace of mind.

These doors are made up of 17 laminations making the door nearly 10% thicker than most composite doors. By investing in our doors, you’ll be able to enjoy an unrivalled degree of security and performance.

Due to the inherent thickness of our composite doors, they can offer a much higher lifespan than conventional composite door designs. Outdated designs can often warp out of shape over time, effecting door performance and appearance.

This solid timber core has a unique moisture barrier system that prevents moisture build-up, helping to protect the door from bowing, warping or swelling. The door slab has a bowing tolerance of just 3 millimetres. This means that if your door were to bow even slightly, we would replace your door slab free of charge.

Our doors are one of the heaviest doors on the market, making them the sturdiest and most secure composite door.

Other Brands

Many other brands of composite doors provide a core that is made from soft timber or even a high density polyurethane foam. These cores can be enough in providing your home with a solid, durable door. However, with a softer core, the door is automatically more vulnerable to break-ins.

The ABS Ultimate lock will remain secure after forced entry snapping attacks and in most cases will still be operable with the key from the inside. This means that you won’t be trapped inside your home should the lock be attacked.


Although inherently low maintenance in their design, our composite doors will require a little TLC over their long lifespan to ensure they are always offering you the very best standards of performance and appearance. It ensures they will be a worthwhile investment for your home.
