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.
