The big door debate – uPVC vs Composite?

As with any home improvement project a great deal of time will be spent researching the various options that are available.

If you are looking to install new doors, then a primary consideration will be the material that your doors can be made from: do you select uPVC or composite doors?

Here at Formula One we pride ourselves on offering a wide range of both types of door and have a team of experts who can advise and guide you through the decision-making process.

So, let’s start at the beginning: what is a uPVC door and what is a composite door and what are their advantages and disadvantages?

What is a uPVC door?

uPVC or Unplasticised Polyvinyl Chloride is an exceptionally durable plastic. It has become one of the most widely used materials for external doors in UK homes. Its hard-wearing properties mean that it can withstand everyday life and is easy to look after. It is also a relatively cheap material, making it affordable to many.

Prone to discolouration over time however, the lifespan of a uPVC door is usually shorter than composite doors. In addition, being largely plastic based uPVC doors cannot be recycled and so have more of an impact on the environment when it comes to disposal. That being said, with an average lifespan of around 15-20 years, uPVC doors offer great value for money and also have many security features to help protect your home.

uPVC pros

      • Value for money
      • Good security features
      • Durable and easy to maintain

uPVC cons

      • Prone to discolouration
      • Shorter lifespan than composite

What is a composite door?

Just as the name suggests, a composite door is constructed from a combination of products, usually uPVC, steel, wood, glass and insulating foam. Composite doors are therefore somewhat more expensive than standard uPVC however they also have a number of advantages too.

Composite doors offer increased security benefits and have a choice of styles and finishes. As mentioned, these options do come at a higher price. In addition, composite doors offer better thermal insulation than their uPVC cousins due to the nature of their construction and being up to 10% thicker than other doors, helping to keep your home cool in summer and warmer in colder weather.

Despite their higher price tag, composite doors come with a lengthy guarantee making them a great long-term investment for those with a slightly higher budget.

Composite pros

      • Enhanced security
      • Better thermal insulation
      • Wide choice of colour and style of finish
      • Long life-span

Composite cons

      • Higher price tag
