There’s plenty to consider when deciding on the type of external doors to install on your property. These days, most homeowners and developers are choosing between composite or UPVC doors. These two materials offer durability, energy efficiency, a range of design styles, and are compatible with various locks.
Of course, your choice will depend on your circumstances and priorities —some people prioritise appearance, others are more concerned about lifespan and cost. But the factor everyone is rightly concerned about is security —the front door is the most common entry point for domestic burglaries in the UK.
In this article, we’ll explain the main differences between composite and UPVC doors, with a special focus on security, to help you make an informed choice.
The differences between composite and UPVC doors
UPVC doors are made from a galvanised steel frame, which is encased with a rigid plastic-like material, known as unplasticised polyvinyl chloride, or UPVC for short. UPVC doors are moulded on top of a single frame creating a thermally-efficient seal, whilst also being a cost-efficient manufacturing process.
Composite doors are made by combining various materials including steel, wood, and insulating foam. This core structure is then encased in glass-reinforced plastic (GRP) to create a fully-weatherproof door.
Composite vs UPVC doors: Security
UPVC doors have a steel frame and some UPVC doors have reinforced frames to improve their security rating. Unfortunately, the standard locks that come on older UPVC doors are easily broken or picked, but more modern UPVC doors are often fitted with more secure multi-point locking systems.
Our article on the types of locks and locking systems used in the UK goes into detail on their pros and cons, including if they’re insurance-approved. You can always add additional bolts or chains to your doors, but the best solution for a subpar lock or locking system is to replace it with a robust lock.
When it comes to your external doors, it makes good sense to fit a lock that complies with British Standard 3261. This is one of the strong points of composite doors —they are generally thicker than UPVC doors, meaning composite doors can be fitted with locking systems that meet the BS3261 standard, such as Mortice or Euro sash and dead locks. Also keep in mind that, as well as adding to the security rating of the door, additional thickness also improves soundproofing and energy efficiency.
Composite vs UPVC doors: Style
UPVC doors gained popularity in the 80s and are still the most commonly used door for large swathes of contemporary developments. They provide fewer options in terms of style and aesthetics but there are manufacturers creating UPVC doors that go beyond the stereotypical simple, white design.
Composite doors offer a much wider range of styles and finishes and are often chosen when replacing old timber doors on traditional or period properties. Composite doors can have sleek, modern finishes with stylish elements or mimic natural wood grain.
Composite vs UPVC doors: Lifespan
The lifespan of your external doors depends on various factors including weather conditions, amount of use and the level of ongoing maintenance. UPVC doors have an expected lifespan of 20 years, with some doors remaining in good working condition for 25 years.
Composite doors, on the other hand, have a longer lifespan than UPVC doors, with most composite designs expected to last 30 years when cared for properly.
A common problem we deal with on both UPVC and composite doors is lock misalignment. The main cause of misalignment is door drop, which can result from simple wear and tear, repeated use over the years, and door slamming. Misaligned locks are usually a simple fix, but prevention is always the best approach. Being gentle with doors, particularly the door handle and locking mechanism will improve the longevity of your external doors.
Composite vs UPVC doors: Maintenance
As we’ve mentioned, taking care of your external doors can significantly increase their lifespan and reduce the need for lock repairs or replacements.
UPVC doors are prone to discolouration and can go from white to yellow over time. If you notice this happening, you can use a suitable exterior paint to bring back that brilliant white appearance. Composite doors are much more resilient to warping, and fading and generally require much less ongoing maintenance.
Composite vs UPVC doors: Cost
UPVC doors are the more affordable option. The higher upfront cost of composite doors reflects their longer lifespan, aesthetic appeal and better security rating.
Are composite doors better than UPVC doors?
In our guide to the most secure front doors, we compared the pros and cons of timber, UPVC and composite doors. Our comparison found that composite doors are the clear winner due to their longer lifespan and the level of security they provide.
Also keep in mind that, because composite doors are thicker than UPVC ones, they are compatible with a much wider range of locks and locking mechanisms. This gives you more options and control when it comes to securing your property.
The cost difference can be a sticking point for many, but know that the additional upfront cost of a composite door is offset in the long run. This is due to the fact that composite doors are much more energy-efficient than UPVC doors, helping you save on your energy bills.
