Composite doors have become the most popular choice for homeowners wanting to improve the look of their property with a robust door that offers maximum security and durability. But what exactly are they, what make them so unique and what are the benefits on offer? In this blog post we’ll answer all of these questions and help you decide if a composite door is right for you.

What are composite doors made of?

Composite doors are made up of a variety of different materials, each with their own benefits. This means composite doors offer a wider range of benefits than a standard door made of one material.

Most composite doors have a strong timber frame at their core. This gives the door its core strength, and because timber is a natural insulator helps reduce the loss of heat from your home.

The timber frame is then surrounded and protected by one or more additional materials. Commonly, uPVC (unplasticised polyvinyl chloride) is used as it is highly weather resistant protecting the wooden frame within from things like rot or warping. It’s also extremely versatile in terms of design options and finishes, allowing for a variety of different styles to suit your home.

Some composite doors use additional layers of lamination, further insulating the door and protecting the frame, along with  a GRP (glass-reinforced plastic) coating for added durability. Doors can be manufactured using just one of these materials, but through a combination of two or more a superior door quality is achieved.

Are composite doors expensive?

Composite doors generally cost more than other types of doors, but in terms of value for money they reign supreme. Their unique construction using a range of materials means they offer far more benefits as we’ve already mentioned. Although the initial cost might be a bit higher, the financial benefit in the long run is likely to be higher due to their superior energy efficiency and the security they offer for your home.
