Our Composite Doors Range
Rockdoors are available in a wide selection of unique styles and stunning colour options. Whether you’re looking for a new front door, back door, or something more distinctive, such as double doors, French doors, or stable doors, there’s a Rockdoor to suit your needs. With such a broad choice available, you’ll find a Rockdoor composite door that perfectly complements the look and style of your home.
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 is required, and they can easily be cleaned with soap and water.
A typical composite door in the UK can be made 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. Rather than using timber, which often swells and bows, a Rockdoor uses a high-density core which is 60% stronger than standard composite doors.
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 manufacturer of the composite door. The Rockdoor is a natural evolution, further improving the security and thermal features of uPVC doors.
In fact, Rockdoor’s range of composite doors has 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!
