What Is A Composite Door?

Composite is a term used to describe something when it is made up of many different parts or elements. Composite doors are becoming an extremely popular external door style due to their robustness, resilience, and appearance. A composite door is made from a combination of materials including uPVC, timber, and laminated door skin. The door is built with a highly weatherproof and durable acrylic layer. The materials that make up a composite door are combined and glued under high pressure conditions. Creating an external door that will outperform other styles, such as the uPVC door.

A composite door is designed to appear like a traditional wooden door, however, due to the materials it is created with, it’s more durable, weather resistant and thermally efficient. Composite doors have an outer frame, subframe and a solid timber core, that provides them with the premium quality standards every time. We have developed our composite door design over time to create the very best composite door product on the market. Composite doors are the perfect modern day solution to all your front door problems. When compared with uPVC or wooden doors, a composite door is designed with the flaws of traditional door styles in mind.


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.

Benefits of a Composite Door

For both urban and rural homes alike the front door is the focal point, protecting the household from intruders and natural elements whilst still being affordable and reflecting the homes’ individuality. Choosing an Endurance composite door will allow you to create a design that suits your technical and design specifications.

Composite doors offer your property a security upgrade. Our doors have been subject to multiple controlled security tests to reenact the most common forms of attempted burglary. Even the toughest tools will find difficulty in creating a hole through the core of the door.

Composite doors will protect your home against the weather. Combined with the perfect installation, you will be able to prevent any unwanted elements from entering your home. A standard composite door is 44mm thick which promotes strength and security. Our composite doors are 10% thicker than the standard designs (48mm) and offer a solid timber core.

While many people tend to choose the cheaper door alternatives to save on the overall cost, these can end up causing problems that go far beyond their initial guarantee period and while homeowners may not realise it, there is a great way to get the best of all worlds between security, strength and style.

What Is The Difference Between A Composite Door and a uPVC Door?

Endurance composite doors are manufactured in the UK and are 10% thicker than the average composite front door and feature a solid timber core. Our doors are 48mm thick, which is 4mm thicker than the standard. The 48mm thick timber core delivers unrivalled dimensional stability to eliminate the possibility of warping over time.

The door leaf is made up of 17 laminations with a solid timber core. We use BBA accredited, engineered LVL (laminated veneered lumber) which provide our doors with lateral strength.  We use 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.

In addition to this, each door is manufactured with an integrated Moisture Barrier System in the base of the door. This extruded cellular profile can protect your door against water damage, delamination and helps to maintain the integrity of the doors over time.

Endurance Composite Doors are available in 18 different colours that can perfectly complement any home, rural or urban. We offer you a wide range of customisation options so you can tailor your entrance to suit your personal style and existing decor.

Whereas when comparing composite doors vs uPVC doors are created with different materials that make them differ in the front door industry. uPVC doors are made entirely from plastic, which although makes it an effective door. Composite doors, however, offer all the same functionalities, but to a higher standard.
