Composite vs uPVC Doors: The Key Differences
Deciding on which door to choose for a home improvement often comes down to several criteria – size, style, colour and material. Two of the most popular door materials are composite and uPVC, and each material has its own set of pros and cons.
At Green Doors, on top of our sustainable range of pre-loved and pre-made doors, we like to help people with their purchase and offer the top guidance to ensure the perfect choice. This blog explores composite vs uPVC doors, and will answer, are composite doors better than uPVC?
8 Differences Between Composite and uPVC Doors
A uPVC door is made from unplasticised polyvinyl chloride. It is lightweight, cost-effective and popular in modern homes for its low maintenance and strong insulation.
A composite door is made from a mix of materials. These often include timber, reinforced plastics, insulation foam and a GRP (glass reinforced plastic) outer skin. This layered construction creates a stronger and more durable door.
1. Materials & Construction
The core difference between the two door types comes from how they’re built. A composite door is made from several materials bonded together, with wood, GRP, insulation foam and reinforced plastics being the common choices. This blend creates a rigid door that handles impact and weather extremely well.
On the other hand, a uPVC door is made from unplasticised polyvinyl chloride and features a hollow but reinforced internal structure. uPVC is lighter, simpler in construction and less dense, which affects strength and insulation performance.
When comparing the two door types, composite is definitely a far better material as it is layered, which means that energy efficiency and safety is much better.
2. Appearance & Style Options
One of the biggest differences between composite and uPVC doors is the visuals and style options. It’s safe to say that composite doors offer a more premium look with a wider range of colours, finishes and realistic woodgrain effects. Composite doors can be styled to suit modern or traditional homes and tend to look more substantial on the property.
Unfortunately, uPVC doors have fewer style possibilities, and although modern designs have improved and come a long way, they still lean toward a more basic appearance and rarely achieve the texture or weight of a composite finish.
3. Durability & Lifespan
Are composite doors better than uPVC when it comes to durability? It’s another win for composite, as the combined materials make it more resistant to warping, swelling, cracking and fading than uPVC. The GRP layer also provides a strong barrier against UV and harsh weather.
uPVC is still durable but can become discoloured or brittle over time, especially in strong sunlight. Composite doors outlast uPVC by several years.
4. Security Levels
Both materials for doors provide good levels of security for homeowners. However, composite doors have a solid core and reinforced skins to provide better resistance against forced entry. uPVC doors are relatively secure for most homes, but the lightweight build makes these doors easier to damage compared with composite designs.
5. Energy Efficiency
Most composite doors are rated A or A+ for energy efficiency, as the solid core’s thickness helps reduce heat loss and lower energy bills. uPVC doors also offer good insulation but perform slightly lower in cold weather. Modern uPVC doors will likely feature multi-chambered frames and insulated designs, so if your main concern is energy efficiency, both door types are desirable in this category.
6. Maintenance Requirements
When it comes to looking after your doors, there is no clear winner between composite vs uPVC. Both doors are very low maintenance and usually only need a wipe down. Composite surfaces are very resistant to scratches and fading. uPVC doors require simple cleaning, but may show wear more quickly and can be prone to slight colour changes over time.
7. Cost Comparison
For those after a more cost-conscious choice, uPVC doors are more affordable. The reason for composite doors costing more is that the construction is more advanced and the materials are of a higher grade. Although the upfront price is greater, many homeowners see better long-term value with composite doors because of their lifespan and performance.
8. Environmental Impact
uPVC doors are far easier to recycle and often contain recycled content, but manufacturing uPVC takes higher energy usage. Composite doors use mixed materials that can be challenging and complex to recycle. However, their long lifespan reduces the need for replacements. Deciding on the greener option will depend on whether you value recyclability or longevity.
The great news is that if you choose to buy a second hand door from us, you’ll be extending the life span of a door, which will be a zero-carbon purchase.

Best Choice for Different Situations
A composite door suits homeowners who want long-term value, higher security and a premium look. It is ideal for front doors and properties where kerb appeal or performance matters.
A uPVC door is the better option for those with tighter budgets, rental properties, secondary entrances or homes that need a simple, low-cost replacement. Budget, style preferences and the type of property usually determine the right choice.
How to Choose Between Composite and uPVC Doors
What to Consider: Budget, Style, Property Type
Start with your budget and how long you plan to stay in the property. You should also consider the style of the building and how much insulation or security you need. For a modern or high-value home, a composite door may complement the appearance better.
When a Composite Door Makes More Sense
Are composite doors better than uPVC? In many regards, yes. Choose a composite door if you want stronger security, a more premium finish or better long-term durability. It is also the best option for improving kerb appeal or boosting energy efficiency.
When a uPVC Door Is the Better Option
UPVC doors make sense if you’re carrying out a home renovation project for a garden room, shed or garage.

Composite vs uPVC Doors: FAQs
Is a composite door better than uPVC?
Many people say a composite door is better than a uPVC door because it offers higher security, stronger construction and better insulation. It also provides a more premium appearance with a wider range of finishes. However, uPVC doors still perform well for everyday use and are much more affordable.
The better choice depends on your priorities. If you want durability, kerb appeal and long-term value, composite is the preferred option.
What are the disadvantages of a composite door?
The biggest disadvantage of a composite door is the higher price, since the materials and construction are more advanced.
Do composite doors swell in the heat?
Composite doors are designed to resist warping, swelling and shrinking, thanks to the GRP outer skin and stable internal structure. During extreme heat, any door can expand, but composite designs control this movement much better than timber and uPVC.
Is composite cheaper than uPVC?
No, composite doors are more expensive than uPVC doors, as the multi-layered construction, added strength, premium finishes and enhanced insulation create a higher initial price. But spending that little bit extra is worthwhile because composite doors provide better long-term value, as they enhance kerb appeal and feature a more premium finish.
How long does each type of door last?
With good maintenance, both door types can last for decades. uPVC doors typically last between 20 and 30 years, while composite doors can last for 30+ years.
Which is more secure: composite or uPVC?
Composite doors are considered to be more secure because of their solid core and reinforced GRP skin. The method of construction makes them harder to force open and provides strong resistance to impacts. uPVC doors still offer ample security when fitted with a modern multipoint locking system, that has a secure barrel.
What types of composite and uPVC doors can you purchase?
We stock a wide range of composite and uPVC doors, including traditional front doors, patio sliding doors, bi-fold doors, French doors and back doors. Our range is available in various colours, finishes and glass options to suit both contemporary and period properties.
