Guide to What Composite Doors Are Made From

Complete your home in style and discover luxury and comfort with the best composite doors in the UK. Forget traditional doors - these are far better options with guarantees for durability and security.

Composite doors are taking over from wooden doors - and for a good reason - but why should you also choose them? The secret lies in what they are made of, so let's delve into what composite doors are made of and their benefits over doors made of solid timber.

What Materials Are in a Composite Door?

Composite doors are intricately designed and manufactured using highly efficient materials, including GRP (glass-reinforced plastic), which performs much better than uPVC doors.

The GRP is moulded to have a grainy texture for a fantastic visual aesthetic while retaining its durability.

The core is filled with a solid wood interior contributing to an energy-efficient home. This also makes the composite door design highly advantageous according to energy efficiency standards in the UK.

Plus, all edges are protected by a weatherproof polymer, preventing elements such as rain from permeating to the core and causing significant damage over time.

All materials used in manufacturing composite doors are made for beauty and durability, hence why they are one of the leading solutions for exterior doors in the UK.

Composite Doors Are Very Low Maintenance

One of the most common problems with wood doors is that the panels might start to peel away over time, or the solid timber core might bulge.

As a result, timber door designs and some single material doors are not the best for the British climate.

Homeowners have to maintain doors of this type constantly, and even then, they have to be wholly replaced sooner than a composite door which has made for high-pressure conditions.

Most composite doors are significantly low maintenance and don't require much maintenance. You can find more tips on caring for your composite door in our blog.

You only need some soapy water and a cloth or sponge to clean away the dirt. High-endurance composite doors made of materials such as GRP with weatherproof edges have longer guarantees, so you won't have to replace your door very often.

Do Composite Doors Fade in the Sun?

When in the sun, some doors can fade and be damaged, which can raise concerns about if composite doors fade or not.

Fading and surface chipping are well-known disadvantages of solid timber doors that drove the growth of uPVC door and composite door development.

The design was a solution to doors degrading due to prolonged heat exposure, dampness, and temperature changes brought about by the changing seasons.

Each composite door has individual components that are weatherproof and equipped for heavy-duty use. They are the perfect door for exteriors since this door excels under all harsh weather elements.

Due to their resiliency, composite doors don't quickly fade in the sun, unlike other doors made with less durable components.

For example, wood doors require constant attention with polish and weather-resistant paint, whereas on the other hand, you can get by with just some soap and water with a composite door design.

Are Composite Front Doors Secure?

Your security takes priority, and you should expect no less from a composite door. With security concerns such as lock-picking, drilling, and other forms of tampering becoming more widespread, most composite door designs have high-end locks with anti-tamper security measures.

One of these locking mechanisms is the ABS security cylinder with PAS24: 2016 compliance. Also, the sturdy design and hinging mechanism make for higher security and less malicious tampering probability.

Even the solid timber core makes the door sturdier than wood panel designs such as hollow core doors. To go the extra mile, some internal frame mechanisms make it harder for tampering as well, depending on their security mechanisms.

What Is the Average Lifespan of a Composite Front Door?

A composite front door lasts much longer than traditional wooden doors, with an average life expectancy of around 30 years.

Composites are highly durable and can last even longer than this without requiring replacement or major repairs.

However, after approximately 30 years or as needed, you might want to replace, repair, or maintain the seals and other hardware that is not as durable.

For example, door hinges might need to be greased; door handles might need repairs or replacements; all these minor preventative maintenance tasks could extend the longevity of your door significantly.

Throughout its lifespan, you shouldn't have any significant problems regarding its thermal performance either, making it a worthwhile investment.

How Good Are Composite Doors For Insulation?

Perhaps you are wondering if composite doors are good for insulation. As you might know, doors and windows are the prime suspects for losing heat and thus, energy-conscious homeowners require doors with sufficient heat retention. Fortunately, since composite doors are made out of different materials, they are designed to be highly energy-efficient.

A composite door of warm foam or solid timber core retains heat much better than traditional uPVC doors and wood solutions.

Some composite door ranges have 1.4 W/m²K U-Value depending on the specific materials used. As a result, this type of door is energy-efficient, and the design is good enough for harsher climates.

This energy-efficiency feature makes composite doors even more desirable in the UK, with all the developments gearing toward a lower carbon footprint.

Are Composite Doors Worth the Money?

Composite door prices are a bit higher than traditional timber doors and many other designs on the market. Is the price justified for a composite door? Yes, when you consider all the benefits of this type of door.

High-endurance composite doors retain heat through thermal efficiency, surpassing some of the most durable uPVC door solutions.

As a result, you save extra costs that could otherwise be lost with more traditional door designs. At the same time, with the thermal efficiency provided by these doors, you can contribute to your home being more compliant with energy-efficiency initiatives from the government.

In addition, the durability and easy maintenance of composite door designs can add more value to properties. The different materials used make the blended door option last longer, even in harsh weather conditions; therefore, in a nutshell, composite doors are well worth their price.

Can You Repaint a Composite Door?

Composite doors are perfect for their versatility. Whether you recognise slight fading after long years of service or want to change the door colour, the process is straightforward and convenient.

In fact, "DIY-ers" might prefer a composite door over other traditional alternatives. The reason is there is less surface preparation and materials required.

Before painting or rejuvenating the colour, simply wiping it down to remove any excess dust or dirt is all there is to it. No sandpapers or priming is needed depending on the scope of your composite door's paint job.

When using Polytrol to brighten up the colour again, the process is much more straightforward than repainting. This is another option that composite doors made from high-grade polymers have when you want to change it up.
