Robust and Stylish

Composite doors are a beautiful door option and are much thicker than uPVC doors. SRJ are proud to offer a new 70mm thick composite door, providing the end of the problematic 40mm composite doors on the market that many other companies offer.

Our composite front doors offer an internal core far superior to timber and carbon alternatives, using stable fibre glass reinforcement to ensure the door withstands weather conditions and won’t warp / crack.

Carbon and timber internals can expand, contract and bend, which is why we only use the most stable materials on the market for our composite doors.

These doors also use aluminium thresholds which are thermally broken, preventing condensation. Triple glazed units are used as standard with a 70mm thick slab.

Their inherently robust structure brings a certain peace of mind that doesn’t come with other door options. When you choose a composite door from SRJ Windows, you’ll be able to enjoy the best in style, innovation and security.

To keep the winter winds out of your home, our composite doors are double rebated, which means no more draughty hinges or locks . All of our doors are tested to the very latest British / European standards for air, gusting performance and air via BSI and BBA.

With a new front door from SRJ you won’t have to settle for anything less than a completely secure addition to your home. Anti-bump, anti-drill, anti-pick and anti-snap Kitemarked cylinder lock barrels are fitted as standard in these doors.

The composite doors that we offer feature highly secure locking systems with protecting your loved ones from intruders and forced entry.

We understand that bringing the perfect composite door to your home is all about how it suits your tastes, as well as the style of your home. This is why we offer many distinct ranges of composite doors for you to choose from. No matter what type of home you have, or what door you’re after, we’ll have something to suit, whether your style be traditional or contemporary. We can even customise your new composite door with features such as ultra modern flush stainless steel glass surrounds, and flush overlapping glass surrounds on the glazed sections.


Our composite doors are available in many different colour options and styles, designed to stay looking good year after year. All colours are available on the inside and the outside of the door to ensure a consistent aesthetic. Colour options include Steel Blue, Dark Red, Rosewood, Oak, White, Burgundy, Chartwell Green, Anthracite Grey and many others – check out our brochures for a full range of colour options.

Whether you’re looking for something decorative, clear or obscure, our composite doors can be fitted with a choice of glazing options. This allows you to control the amount of natural light coming into your home, as well as the privacy you can enjoy. Our glazing options provide you with plenty of choice to ensure your new front door creates a first impression that lasts.

Features & Benefits

For your convenience, our composite doors utilise a modern design that means they require very little input from you to ensure they look as good as they should. The GRP skins on these doors are depression moulded, featuring a timber grain effect and high definition panels. This provides an authentic appearance with minimal maintenance.

All of our composite doors will prove to be a worthwhile investment for your home, manufactured from high impact materials to ensure impressive durability. Alongside this, they also contains technology which prevents your door from cracking, bending or warping when exposed to the elements. It’s never been easier to enjoy lasting quality that will continue to keep you warm and comfortable across the year.
