Hopefully, you’ll never have to deal with unwanted visitors attempting to force their way in, but if you do, your composite door will resist them long enough for you to call the Police. That’s why we believe composite doors are a worthy investment. They provide protection and peace of mind as well as look good.

Why Composite Doors Are More Secure

It’s not pleasant to think about someone trying to break into your house, but they won’t get in through your composite door. If you’ve not seen it yet, we recommend watching our sledgehammer test. There’s no finer demonstration of how tough our doors are than seeing a former Gladiator failing to break through one with a sledgehammer.

The reason they’re so resilient is because of how they’re made. Traditional timber doors are made of a single piece of wood, but as their name suggests, composite doors are built with multiple materials. Each of ours is built from Kerto Laminated Veneer Lumber, an exceptionally solid piece of engineered timber. They have 17 cross-layers and are some of the most secure doors on the market. Their 48mm core makes them 10% thicker than most of our competitors, so you can sleep soundly knowing that your door is keeping your house safe.

Secure Locking Systems

Additionally, Endurance Doors benefit from the increased security of advanced locking mechanisms. We fit our doors with the ABS Master Cylinder, a high security system that meets the requirements of the British Kitemark, TS007 3* and Sold Secure Diamond testing criteria. They’re also accredited with Secured By Design (SBD) approval as part of the Police Crime Preventions Initiative.

The ABS Master cylinder has been designed to resist all known methods of breaking into a euro cylinder while remaining operable from the inside. If your composite door is attacked, a hidden lock inside the cylinder’s core is activated to provide extra protection. This means that the lock won’t be a weak point, and even the most talented safe-cracker will have trouble getting in.

How Are Composite Doors Made?

17 Laminations

Our composite doors are made up of 17 laminations with a solid timber core. We use BBA accredited, engineered LVL (laminated veneered lumber.). Our 48mm thick core offers exceptional stability and eliminates the possibility of warping over time. Each door is manufactured with an integrated Moisture Barrier System in the base of the door which protects your door from water damage, delamination and maintains its integrity, avoiding common problems with composite doors.

Door Skin

Endurance composite doors feature a laminated door skin with a highly weatherproof and durable acrylic layer, offering exciting vivid colours and luxurious wood effect designs that perfectly match the door frames into which they are installed. Our replacement front doors are finished with a foiled 3D Cool Skin that features an embossed woodgrain texture to offer a surface that won’t crack or fade. Available in 16 colours ranging from neutral shades to bold bright tones, you can create a composite door solution that is colour lasting and will continue to look great even after years of use. Once you’ve selected the style, and design of your new door and applied your preferred colour you can add finishing touches to your composite door with a wide selection of hardware and security options. Select from handles, knockers and letter plates to personalise your door and make it your own.

Hardware Options

Created to blend into the surroundings of your property and to complement your existing décor, we know that you’ll be pleased with the finished result.

what are the benefits of the solid timber core external doors

Solid Timber Core

The Endurance door has a solid core unlike others. This robustness means there are more advantages and far fewer problems with composite doors from us compared to other companies.

With 48mm thick cross-bonded veneered laminated timber door lead, Endurance composite doors deliver lateral strength and unrivalled stability.

We use Kerto LVL for our solid core, a material which is incredibly strong and dimensionally stable timber beam. The makeup of our solid core is designed so that it can be cut to any height or width without affecting its integral strength.

Our solid core competitors use cores that incorporate less dense mixed species woods with a stile and rail subframe. The core’s strength comes from the outer subframe in these doors. A narrow or short door involves cutting into this subframe and cutting away the strength of the door. These doors don’t always hold their shape when facing the temperature changes of British weather and central heating.

We are so confident in the quality of our Endurance composite door we offer a 3mm bowing guarantee on our doors.
