Composite doors are made of a selection of materials including a solid timber core, glass reinforced plastic and uPVC to name a few.  Each material is chosen for its specific properties, fused together to result in one of the strongest door materials currently on the market.

Unlike uPVC doors which are made of just plastic, our composite doors are made from a number of materials that are pressed and glued together under high pressure conditions. The idea for composite doors came about to find a solution to problems often found in single-material doors, by selecting specific materials with certain properties to counteract them.

When you select a composite door for your home you’re investing in a sturdy door frame made from tough and robust materials. This promises to add extra security, enhanced weatherproofing and provides you with complete peace of mind about the safety and protection of your family and home.

The advantages of a composite door include the extensive choice you get when it comes to tailoring them to your personal taste and requirements. With an array of colours to choose from, as well as woodgrain effects, textures and finishes, you can create a unique composite door that is bespoke to your home.

Our composite doors are a low maintenance and durable solution for your property. The colour and aesthetic will last due to state of the art manufacturing techniques that ensure your composite door is resistant to weathering. You won’t have to worry about spending time or money on the upkeep of your composite doors even after heavy or frequent use.

The term ‘composite’ literally means made up of several parts or elements and this is exactly what a composite door is. Our composite doors are made up of a number of materials including a 48mm thick cross-bonded, veneered, laminated, solid timber core. This is what makes our Endurance residential doors stand out from the rest with our doors being nearly 10% thicker than average composite doors.

Due to the way in which we have developed and enhanced our manufacturing technique over the years, our composite doors have evolved and improved over time to become the market leaders. Currently unrivalled on the existing market, Endurance residential doors are the ultimate fit for any property with a list of features and benefits that come with them.

What is GRP? (Glass Reinforced Plastic)

Glass-reinforced plastic is a fiber reinforced polymer made of a plastic matrix. This is reinforced by fine fibers of glass which results in an extremely lightweight and robust material that outclasses carbon fiber. Flexible in nature and easily moulded to fit with a number of designs, it is the perfect material to finish our composite doors.

GRP offers the traditional look and feel of timber, without any of the issues that wood can often suffer with, making it the ideal solution. You won’t have to worry about re-staining or repainting your composite doors as the glass reinforced plastic offers a long-lasting and durable finish that you can enjoy for years to come.


All of our composite doors are made up of 17 engineered timber laminates. With an exceptional GRP skin on top of this, our composite doors offer increased thermal efficiency to any property they are installed into. Offering the best heat retention and achieving impressive energy ratings, our composite doors are able to assist in lowering energy bills and reducing your carbon footprint.

The main aim when it comes to increased insulation is to retain heat to keep your home warmer for longer. This makes your home a more comfortable and inviting place to spend time for all of the family. Our composite doors will also provide a watertight solution so that your home will stay dry and moisture free, no matter the weather.


Our composite doors are renowned for their solidity and security. With a timber core, they should be your first choice when it comes to securing your home and keeping you safe and protected. Our 48mm thick solid timber door slab has proven to be sledgehammer proof, which gives you an idea about the level of security they provide.

Each of our doors have undergone controlled security tests to replicate common forms of attempted burglary or break ins, to make sure that the inner core can withstand an attack and maintain its integrity. Enjoy complete peace of mind by choosing Endurance composite doors.

You can upgrade your Endurance composite door to include the highest rated security cylinder, developed to counteract lock snapping in order to gain entry. The ATK is a euro cylinder with the Master Locksmith Associations highest rating as well as achieving the British Kitemark and Secured by Design accreditations.
