When specifying external doors, you have three options – composite, UPVC, and timber – with composite doors being the most expensive option. You want to know if the cost is worth it, and what advantages composite doors have.

This article provides clarity on the topic to help you choose.

The short answer 

A like-for-like composite door has superior security, efficiency, and longevity compared to modern timber and UPVC doors.

Simply put, a composite door is a better door, but that is not to say that UPVC and timber doors are bad choices. Composite is a newer door technology that requires a bigger investment, so you must balance things before deciding.

The advantages and disadvantages of composite doors

Here are the advantages and disadvantages of composite doors:

Advantages

  • Security
  • Thermal efficiency
  • Durability
  • Longevity
  • Lifetime cost (a composite door lasts at least twice as long as a timber or UPVC door), making it cheaper in the long run.

Disadvantages

  • Higher upfront cost
  • Thickness (a composite door is around twice as thick as a UPVC door, so not all doorways are compatible with the frame).

Composite versus UPVC 

Composite doors are around twice as thick as UPVC doors and filled with a solid core, making them more resilient to impacts, and the extra thickness means they have better thermal qualities, helping your home retain heat.

While UPVC can discolour with age, composite doesn’t discolour, and it is more resistant to abrasion, scratches and puncture.

The solid feel of a composite door inspires confidence and mimics the feel of hardwood, so it’s the best choice if you want a solid door.

Composite versus timber 

The obvious advantage to a composite door over timber is that composite doesn’t warp or rot. It requires zero maintenance and will never need refurbishing, and it should last the house’s lifetime and look new after a decade.

While timber doors have good insulative qualities, composite doors are superior, with more thickness and a thermally efficient core.

Because timber needs painting, maintenance, and eventually refurbishment, composite doors are also cost positive over their lifetime versus timber.

Is a composite door right for you?

The question you need to answer is how much you are willing to compromise on the qualities of composite doors to save a few quid. All things equal, composite doors are the best on the market!

A composite door will set you back 30-40% more than a like-for-like UPVC door, so a £500 UPVC door might cost £700 in composite form.

Another factor is the thickness of composite doors. Composite doors are usually 20mm thicker than UPVC, so they require a thicker frame. Your existing doorway may not be suitable, so getting an expert out for a survey is worthwhile.

In our opinion, composite doors are a worthwhile upgrade over UPVC because they are solid, more durable and don’t discolour (UPVC can yellow in the sun over several years). The security advantages are also enormous.
