Contact Us

What are composite doors made of?

Composite doors are made from a combination of materials, including uPVC, wood, insulating foam, and glass reinforced plastic (GRP). This combination of materials creates a door that is strong, durable, and secure.

How secure are composite doors?

Composite doors are known for their high level of security. They are impact-resistant and designed to withstand forced entry attempts. Many composite doors also come with advanced security features, such as multi-point locking systems and high-security hardware.

Are composite doors energy efficient?

Yes, composite doors are highly energy efficient. The insulating foam core and multiple layers of materials help to minimize heat transfer, reducing energy loss and keeping your home well-insulated. This can lead to lower energy bills and improved comfort.

Can composite doors be customised?

Yes, composite doors can be fully customised to meet your preferences and specifications. There is a wide range of panel and glass designs to choose from, as well as a variety of colours and finishes. You can also add extra features, such as matching side panels and handles, to create a truly personalized look.

How easy are composite doors to maintain?

One of the main advantages of composite doors is their low maintenance requirements. Unlike timber doors, they do not require regular painting or staining. Simply wiping them down with a damp cloth from time to time is enough to keep them looking clean and fresh.
