Composite Doors

Learn more about composite doors from the original manufacturers of the composite door, Rockdoor. Our doors are stylish, strong and certified ‘Secured by Design’.

The Original Composite Door

There’s a reason why we’re called ‘the Original Composite Door’ and it’s because we were the first company to manufacture this type of entrance door.

First manufactured all the way back in 1996, Rockdoor were the pioneers of the composite door movement, right off the back of a turbulent era for homeowners where break-ins were quite common, as people opted for cheaper entrance doors with very basic security measures.

To combat the rise in home burglaries and energy bills, we had an end goal to create the nation’s most stylish, secure, and thermally efficient composite door, and whilst many competitors have since tried to replicate, none are quite like the original.

With nearly over one million units produced and thousands of families still happy nearly 30 years later, the Original Composite Door origins remain true to this day.

Composite doors with built-in security and thermal efficiency

Composite doors are an excellent choice when it comes to selecting an external door for your home. They provide superior security and thermal insulation compared to timber doors, uPVC doors, and standard GRP doors.

When looking for the best composite doors on the market, look no further than Rockdoor, the original manufacturers of the composite door. The Rockdoor composite door is a natural evolution, further improving on the security and thermal features of uPVC doors.

In fact, Rockdoor’s range of composite doors have consistently been found to be one of the most secure doors available in the UK, with studies showing that a Rockdoor is 35% stronger than a typical GRP door!

What are composite doors?

Composite doors have become increasingly popular among homeowners due to their numerous advantages over traditional wooden, uPVC, or metal doors. These include the many security features built into them to keep your home secure, along with the increased energy efficiency to help lower your bills.

Another benefit is the minimal maintenance requirements over some other types of doors. No more painting or varnishing required, and they can easily be cleaned with soap and water. Overall, composite doors are a great choice for homeowners looking for a secure, energy-efficient, low-maintenance, and visually appealing front door.

A typical composite door in the UK can be made up of a mixture of materials such as GRP, Timber and PU Foam, all of which aim to reduce the amount of warm air escaping and cold air entering a property. However not all composite doors are built the same!

Rather than using timber which often swells and bows, a Rockdoor composite door uses a high-density core which is 60% stronger than standard composite doors. This is standard across our entire range of composite front doors, back doors, French doors and stable doors.

Why choose Rockdoor for composite doors?

For over 25 years, we’ve been making composite doors in a whole range of door styles and colours to match the look and style of any home.

Each and every Rockdoor composite door is made to measure, not cut to fit. We do this because composite doors can become weaker when they are cut to fit, which is often the reason for external doors weakening.

This ensures your new door not only protects your family from becoming victims of burglaries, but also increases the thermal efficiency to keep your home warm in the winter.
