Made of stronger stuff

There are many composite door designs across the market, from foam filled to laminated door skins. We have utilised their 25 years in the industry to create a composite door design that stands out, capturing a unique standard of quality that enables Endurance Preferred Installers to gain a competitive edge.

This door style comprises a wide range of innovative features that enable this door to outperform other door designs on the market. One of these is the solid timber core, designed and manufactured to achieve an exceptional standard of security. This core is 48mm thick, created using cross-laminated timber to achieve a door design that is 10% thicker than most solid composite doors.

This core uses Kerto, a laminated veneered lumber (LVL) to ensure Endurance doors offer homeowners an unrivalled degree of internal strength and dimensional stability. Standing as a smart choice of installers to use, these doors are CE marked and certified by VTT Technical Research Centre of Finland, no 184/03 for complete peace of mind.

Due to their impressive design, Endurance doors have also been rigorously tested to make sure they meet the latest standards of security. They are tough and durable, and fitted with the latest locking mechanisms, to keep any unwanted intruders at bay, and protect your loved ones and valuables.

The tests include a manual attack on the locking hardware with tools including a crow bar and mole grips, an unlimited number of 3-minute attacks on the door cylinder, a 3 minute manual attack using chisels and brick bolsters and a hard body impact test to the door leaf at the hinge and locking points using a 50kg steel impactor: they have even held against a sledgehammer attack.

To ensure a consistent standard of security is achieved across the board, we offer the ATK 3 Star Diamond Cylinder. As the UK’s highest accredited lock range, they are sure to offer homeowners the sense of ease that comes with a premium product. These locks have achieved BSI certifications and are designed alongside the Master Locksmith Association.
