A composite door is designed to appear like a traditional wooden door, with cutting-edge benefits. Due to the materials used, it’s more durable, weather resistant and thermally efficient. Composite doors have an outer frame, subframe and a solid timber core, which provides them with the premium quality standards every time. We have refined our composite door design over time to create the very best on the market. Composite doors are the perfect modern solution to all your front door needs. When compared with uPVC or wooden doors, a composite door is designed to counter the flaws of traditional door styles.

The term ‘composite’ literally means made up of several parts or elements, and this is exactly what a composite door is. They 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.

For both urban and rural homes alike, the front door is the focal point. Protect your household from intruders and natural elements whilst still being affordable and reflecting the home’s individuality. Choosing an Endurance composite door will allow you to create a design that suits your technical and personal 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, and our locking mechanisms are designs to resist snapping.

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. Invest in a composite door as a great way to enjoy all the benefits of security, strength and style. Never compromise when you choose Endurance.

Endurance composite doors are expertly manufactured in the UK. They 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 for a durable and low maintenance design.

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.  A laminated door skin combines 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.

Our comparison of composite doors vs uPVC doors is a discussion between the strength of different materials in the front door sector. uPVC doors are made entirely from plastic, which makes for an effective door. Composite doors, however, offer all the same functionalities, but to a higher standard.

Our HomeView Door Designer offers a simple to follow step by step process, enabling you to construct your ideal composite door and see how it looks on your home. We’ll also share your design with up to 3 members of our Installer Partner Network who can offer you a custom quote, based on your exact specifications.

A composite is a material or item made from combining a selection of materials – by combining those materials, the new material is stronger than the individual components.

A composite door is made from a combination of materials that can offer a stronger, thicker door that is durable and has a quality of finish.

The reason that composite doors have become so popular in the UK is their beautiful wood-grain effect finish that looks as good as wood but is easy to look after and lasts up to 35 years.

What is a composite door? It’s a door that won’t fade, warp, crack, weather and will never need painting.

1. The external part of a composite door is made from a 2mm layer of Glass Reinforced Plastic (GRP), also known as fibreglass, the same stuff they use to make fishing boats in the North Sea. It’s tough, weatherproof and moulds perfectly to replicate a wood grain for a door with kerb appeal.
2. The tough exterior GRP panels are fused to an internal frame made from uPVC and layered inside that is another frame of hardwood which makes a double frame of superior stability and rigidity.
3. The internal space of the door is injected with a warm thermal polyurethane foam core that’s 100% CFC and offers excellent heat retaining A-rated insulation to make your door more energy efficient.
4. The outer door frame, constructed from sturdy 70mm uPVC and steel reinforcement, makes composite doors one of the most secure you can buy.

Every composite door we make is handmade to precise measurements from the customer for the perfect fit. The composite door and frame are made together as a set to ensure the door fits as snugly as possible in the frame to eliminate draughts.

Every door is hand sprayed to the colour of choice using a special hard-wearing acrylic paint and then cured in an infrared bake that is so durable your door never needs to be painted again.

You can see the full process that explains what is a composite door and shows from start to finish how a composite door is made in our factory here.

Composite doors have been purposely developed to address the common problems of older front doors such as weathering, fading in colour and constant maintenance. So, choosing a composite front door has considerable benefits over timber and uPVC.

Installing a composite front door is a solid investment that won’t have to be replaced for at least 35 years. Unlike timber, it won’t crack or peel paint and unlike cheap uPVC, won’t warp, fade or look shabby after time.

Composite doors are stronger than the sum of their parts and the materials used in combination mean that the door is more durable than timber or uPVC. They will stand serious wear and tear, bumps and knocks and the external GRP material is especially resistant to denting, kicks and knocks.

One of the most important features of a door is just how strong and secure it is and composite doors have superior security due to the steel-reinforced frame and the internal solidity of the door. The quality of composite doors does vary, so look out for security standards that would mean a burglar is going to find it almost impossible to break through that one.

Old doors have problems from draughts and gaps caused by warping and shifting in the frame. Although wood has good thermal properties, it can’t compare to the insulating core of a composite door and the precision fit manufacture means the door sits perfectly in the frame to eliminate gusty gaps. Composite doors are A-rated for thermal efficiency and will help to retain heat in the home.

There’s no doubt that a beautifully painted timber door looks stunning and can add value to a property. With a specially moulded wood-grain effect surface, the composite door looks just as good as wood but has the benefit of always looking like a freshly painted wood door.

As beautiful as timber looks, wood is a high-maintenance material. The freshly painted look doesn’t last long – wood needs care and attention to stop the door from cracking, rotting or peeling. And wood weathers fast. Composite doors look just as good as wood but have the benefit of only needing a quick wash with a cloth to keep them looking their best – you should expect good looks and a long life out of your composite door.

Traditionally, doors were always made from timber. Then along came uPVC and became the most popular choice for front and back doors. uPVC is more economical when compared to wood and is a lower maintenance option without the need for care and painting.

And now, composite doors are the most popular choice in the UK.

The main difference between a uPVC door and a composite door is that a composite door is made from a combination of materials that offer all the benefits of each. A uPVC door is a singular material and limited by its properties.

A composite door is just as easy to maintain as uPVC but it also looks better than uPVC as it has the moulded wood-effect grain that looks as good as timber.

uPVC doors are still a popular choice but if you want a front door that will be long-lasting and retain its polished exterior composite doors are now a better investment.

Composite doors have very few problems but, as with other doors, they will swell in hot weather, especially if the door is south facing. This is unavoidable, so when your door is installed, make sure it’s fitted to accommodate the natural swelling a door can expect. Also, make sure that your composite door is manufactured to the perfect size so that it doesn’t stick in warm weather.

Another common problem with composite doors and all doors is that after time they drop. Again, this is unavoidable. If your composite door drops, you can adjust the strike plate or the hinges so that it closes easily.

Some people think that it’s a problem that composite doors initially cost more to buy than uPVC doors. However, if you factor in the longevity of the door, when you calculate the cost over its lifespan in comparison to another door then a composite door is a better value investment.

Keeping a door looking bright and glossy can be a challenge, especially if your front door faces serious weathering from wind and rain. uPVC doors are available in bright colours but they can fade over time, especially if they are subject to strong UV light. Timber doors will crack and peel when beaten by rain and dried by hot weather.

Composite doors are finished in a resistant GRP (fibreglass) material that is used on boats – and if a North Sea fishing boat can withstand the elements, your composite door can take whatever is thrown at it.

Composite doors shouldn’t fade – the colours are designed to be vibrant and long-lasting and guaranteed to last far longer than timber and uPVC.

Can you paint a composite door – no, because the paint will not adhere to the surface of the door and will ruin the look of the door.

Some websites suggest using a primer, oil-based paint and a varnish finish. However, this is bad advice.

Glass reinforced plastic is not a suitable base for paint. The skin of the door is designed to be infused with the colour for vibrancy and longevity and to alleviate the need for painting.

If you use gloss paint on the door, you might get it to adhere but it won’t last long – the door will be susceptible to peeling, chipping and weathering. And, by painting a composite door you will never be able to achieve the same quality of finish – you will devalue your door.

Be aware, you may also lose any guarantees you have for the door if you paint it.

If you’re desperate to change the colour of the door, you can speak to the manufacturer about colour bonding and they may be able to do this for you.

Can composite doors be painted? – yes, if the manufacturer is able to take the door away for colour bonding.
