Our composite doors offer our customers fantastic energy efficiency. Thanks to the thermally efficient materials we use in construction and their highly insulted design, this home improvement product can help to keep warmth inside your home.
By reducing the amount of heat that is able to escape your home, you can expect to use your central heating less. This can help lower your energy bill.
Why Choose Our Composite Doors?
All our composite doors are engineered from GRP technology, which stands for Glass Reinforced Plastic, making them a strong and safe option.
Our top of the range engineering also gives our composite doors a smooth, sleek finish, which looks great on the front of any property. Our composite doors are a solid investment: they are guaranteed for 10 years but can last a lifetime with proper maintenance, and there will be no cracking, no colour fading and no warping.
We use a special CFC-free foam in our composite doors that are great at insulation your home and help to keep your energy bills low.
Frequently Asked Questions
Take a look at some of the questions previous customers have asked regarding our composite doors. If there’s something we haven’t covered, contact us online or over the phone to talk to our expert team today.
What is a composite door?
A composite door is built from a mixture of a variety of materials – in other words, it’s a composite of different materials. Because it isn’t made from one sole material, it is often seen as a stronger and more durable choice.
How good are composite doors?
Composite doors are a worthwhile investment as they offer security, thermal efficiency and they can be designed to your personal taste.
As composite doors are created in high-heat, high-pressure environments, this makes them durable and weather resistant. This is important as it makes composite doors resistant from naturally occurring damage (such as heavy rains and winds), and their strength makes them a lot harder to break down in comparison to other door options. Composite doors have also proven to be more energy efficient than uPVC doors.
How long do composite doors last?
If you have a beautiful garden that you want to admire whatever the weather, then installing bifold doors allows you to integrate it seamlessly into your living area. Bifold doors are an excellent way to add value to your home, as they give your house increased natural light and can create a large unobstructed access area to your garden without taking up too much space. An attractive feature for potential buyers, bifold doors are secure, energy efficient and can be a real statement piece in your home.
How much do composite doors cost?
The price of composite doors depends on various factors, such as glazing area and size. To get a tailored cost, use our online quoting tool. Simply enter your design preferences and a few measurements to get a bespoke estimate with no obligation to book.
Happy Customers
Meg Welch
Great job of our new front door. They couldn’t have been more helpful and even fitted earlier than originally planned. Also gave great aftercare advice and at a very reasonable price! Would 100% recommend.
Annette Clemons
Cannot recommend Britannia Windows enough! Joe & Keith, the installers were great – explained what was to be done, showed me everything I needed to know upon completion, very considerate & tidied up really nicely. Very friendly guys who are an asset to the team!!
I LOVE my new windows & door. Such an improvement.
Rachel Godfrey
We have been extremely pleased with Britannia’s service. From the initial quote through to installation they were great and really easy to communicate with. We had our conservatory roof replaced and they were by far the least pushy and most competitive in terms of pricing.
We can definitely recommend their services and will likely be returning again soon for a new front door!
Peter Burgess
Fantastic job from initial phone call through to final tidy-up.
Britannia provided great advice before purchasing my new windows and fitted them to a high standard being punctual and polite throughout.
No request was a problem and I will definitely be using them again and would recommend to friends and family.
Jerry G
Wow a fantastic job by both sales team and fitting team.
Sam provided excellent service and answered any questions that we had. Luke, Dave, Keith and Joe did a fab job at fitting the windows and doors. Never having had anything like this done before I was a little nervous but the guys were clean and tidy and the outcome is amazing.
Would highly recommend.
