Why Choose to Get a Composite Front Door Fitted?
Regarding strength and durability, there is no question that composite is the best material.
Unlike uPVC doors, which are entirely made of plastic, you can be sure all our composite doors fitted are created with a substantial timber core and a GRP (glass reinforced plastic) exterior.
This makes them withstand more significant wear and tear and hold up against any impact. Getting a composite door fitted also provides the following:
Having well-insulated doors to your home is more important than ever. Composite materials help keep the warm in and keep the cold out. Our composite front doors have the highest thermal efficiency and low U-Value, preventing heat transfer and reducing heating bills!
We measure every one of our doors to the customer’s exact specifications, fitting them perfectly within the dimensions of your doorway. Our composite front doors can be customised with our range of colour and glass choices. Transform the appearance of your home with the new door of your dreams.
Unlike uPVC, when you get our composite front doors fitted, they are built to withstand even the heaviest of impacts. Our GRP doors and frames use a Glass Reinforced Polymer (GRP) skin for added strength and durability. You can have the visual effect of a solid timber door with the unparalleled security of composite 48mm solid wood core.
FAQs
Composite doors are made from various materials chosen for their specific properties, which include a fusion of solid timber core that is 48mm and reinforced glass-reinforced plastic and uPVC to make one of the strongest door materials available.
A good quality composite door will be made from the highest quality materials selected for their beneficial properties, meaning they are strong, durable, highly secure and have a high resistance to weathering, and will not react to seasonal changes.
Most GRP doors are made up of multiple GRP skins and are filled with foam to be used as an insulator.
Our GRP doors are solid timber core therefore much more secure and energy efficient. Due to the foam being used in some doors, they can be cheaper but these kinds of doors have a lower U-value than ours.
Solid timber core GRP doors have unrivalled strength, durability and energy efficiency.
Overall, composite doors are a far more premium option than uPVC doors, but they are worth the investment due to their increased durability, security, energy efficiency, and aesthetics.
Composite doors are made from various materials, including a solid timber core, PVC, and glass-reinforced plastic (GRP).
This makes them much stronger and more durable than uPVC doors, made from a single material with a foam-filled core.
Another advantage is that composite doors have a higher level of insulation than uPVC doors, which means they can help reduce your energy bills by keeping your home warmer in the winter and cooler in the summer.

Our composite doors typically start at around £999, with prices varying depending on any customisations and additional features that are added to the design.
The cost of a composite front door is slightly more expensive than your standard uPVC or timber door, but the long-term savings that you will get from having a composite front door is worth it. They are long-lasting without the need for constant repairs or replacements and provide greater energy efficiency.Â
Depending on your requirements, we can simply supply or both supply and fit your composite front door. Our expert and friendly staff are fully trained and highly experienced in hanging doors, ensuring that the finished product looks exactly how you want it to.
U-value is the rating of heat transfer through a structure, meaning it judges how well an object, in this case, our doors, is as an insulator. The units used to measure U-value is W/m2 K and the lower the figure is, the better of an insulator the structure is.
The standard for our composite doors is 1.4W/m2 K, so they have high thermal efficiency and are a great choice for decreasing your carbon footprint. Use of heating and electricity will be lower as heat will be kept in the house better than other doors would and its strong weatherproofing ability will also mean that your home keeps its heat even throughout the coldest winter days.
With its sturdy properties and as it is used on fishing boats in the North Sea, your Composite Door with GRP skin is also lightweight, requires minimal maintenance and we can manufacture it in varying styles so you get your perfect front door.
GRP skins on our composite doors have an extremely high tolerance to warping, bowing and twisting compared to traditional timber doors, so you can enjoy the aesthetically pleasing appearance of a timber door without the problems they bring.
A GRP Door is simply another name for a composite door, so we will also be answering the question, what is a composite door? GRP stands for Glass Reinforced Polymer, the outer skin of a composite door that is moulded to create the woodgrain effect.
A GRP composite door is an entrance door made using a combination of glass-reinforced plastic, thermoset plastic resin, and other materials such as wood or foam.
The outer layer of the door is formed using GRP material which provides excellent resistance to weather, corrosion, and impact. At the same time, the inner core is typically made from high-density foam or other insulating materials to offer energy efficiency and sound insulation.
These doors are gaining popularity as a replacement for traditional doors due to their high levels of security, durability, energy efficiency, and low maintenance requirements.
Additionally, they are available in a wide range of styles, colours, and finishes, making them a versatile and attractive option for homeowners.
