FAQ's

What is a composite back door?

Composite doors are crafted from a range of materials selected for their unique properties, including uPVC, a solid 48mm timber core, and glass-reinforced plastic.

As one of the most robust door materials available, they offer strength, durability, high security, and resistance to weathering. They do not react to seasonal changes, making them ideal for enhancing the security of a property's exterior.

Can I have any composite door as a back door?

Yes, all of our composite doors are available for both front and back installations.

Depending on their size and features, some may be more suitable for the back of your property than others.

You can use our online door builder to design your ideal composite back door and determine which design will best suit your home.
