What Are the Best French Door Materials? (2026 Buyer’s Guide)

French doors have remained a popular option for homeowners since the Renaissance period, and modern French doors are now available in a range of materials offering different aesthetic and performance benefits.

Choosing the right French door material for your home will depend on several factors, including budget, maintenance requirements, thermal performance, security and desired aesthetics to suit your property. Green Doors sells a dynamic range of new and pre-loved French doors spanning materials like aluminium, AluClad, uPVC, wood and steel.

This blog breaks down these French door materials and explains the advantages to help you determine the ideal choice for your home.

What Are French Doors?

Originating in France during the Renaissance, particularly in the 16th and 17th centuries, French doors developed from the period’s growing interest in symmetry, proportion and bringing more light into buildings.

The most common types of French doors use a double-door configuration with double or triple glazing, improved locking systems and thermally efficient frames, available in a range of materials. This has seen them transition from mainly being featured in grand houses and Georgian properties in Britain to being a very common residential feature.

Today, you’ll find most French doors being used for connecting living spaces with gardens, patios and balconies, with each available material offering unique aesthetics and qualities.

What Materials Are French Doors Made From?

Modern French doors are available in a range of materials, such as uPVC, aluminum, timber, steel and composite materials including AluClad. Each offers different advantages in terms of appearance, performance, lifespan, maintenance and price. Let’s look at each in more detail.

uPVC French Doors

Perhaps the most common material homeowners choose for French doors, uPVC is a low-maintenance and cost-effective choice. While not the strongest material, uPVC can still withstand tough weather conditions, making it a popular choice for external French doors.

Modern uPVC French doors feature excellent thermal ratings when they feature multi-chamber frames that trap air and slow heat transfer. They’re incredibly low maintenance and secure too, thanks to options for multipoint locking systems and strong glazing.

French doors made with uPVC frames typically come in standard white colours, but there are options for darker greys and other colours, but they don’t offer the design flexibility that other materials can.

They’re the most affordable option for homeowners because the material is cheap to produce and manufacture in large amounts.

Aluminium French Doors

The next material French doors can be made of is aluminium. Homeowners opt for aluminium French doors for several reasons. One, the frames tend to be slim and maximise the amount of natural light that can pass into the home, as well as offering a very contemporary aesthetic.

Aluminium French doors are also very durable and have become a widely used material for homeowners. The strength of aluminium combined with its lightweight nature means even larger door systems can be used with relative ease. Also designed with excellent thermal performance in mind, the aluminium frames also require little maintenance and can be powder coated in a range of colours as well to prevent fading or peeling. 

Timber French Doors

While a more traditional option, timber French doors still remain popular for new installations. Developments have seen hardwood the go-to option, as it’s far stronger than traditional timber and is often engineered with coatings to withstand adverse weather and improve thermal performance.

While a popular choice, timber French doors will typically require more maintenance over their lifecycle, depending on weather exposure. This often sees French timber doors installed internally, creating entrances between rooms, rather than transitions between the inside and outside.

Steel French Doors

Steel is a popular material choice for French doors because, similar to aluminium, it offers very slim frames and large glazed panels. They often suit older properties with more traditional aesthetics because of the industrial appearance associated with steel windows and doors. 

Steel can provide a robust, long-lasting door system that can incorporate insulated glazing, weather seals, secure locks and thermally improved frames. People often choose steel French doors because they want more character than standard aluminium or uPVC doors, without sacrificing natural light.

Composite AluClad French Doors

The final material we’re covering is composite French doors, and more specifically a material called AluClad. This type is made using a combination of materials, rather than relying on a single frame material. AluClad French doors are constructed with a timber frame on the inside and protective aluminium cladding on the exterior. The aluminium cladding helps protect the timber from rain, UV exposure and changing weather conditions, helping to reduce the need for regular maintenance like repainting or treatment. 

The timber is naturally insulating, and modern AluClad doors can incorporate energy-efficient glazing and seals to further help reduce heat loss. AluClad French doors are also very customisable in terms of colours and finishes, while the internal timber can be stained, painted or finished to complement the room. 

Which French Door Material Is Most Energy Efficient?

uPVC: uPVC French doors generally offer good thermal performance because the frame material is naturally resistant to heat transfer. Multi-chambered profiles can further reduce heat loss, making uPVC a strong option for homeowners focused on energy efficiency.

Aluminium: Aluminium conducts heat more readily than uPVC or timber, but modern aluminium French doors usually incorporate thermal breaks to improve insulation. High-quality systems can perform very well, although their efficiency depends heavily on the frame design and glazing specification.

Timber: Timber is a naturally insulating material and can offer excellent thermal performance when properly manufactured and maintained. However, gaps caused by movement, ageing or poor maintenance reduce efficiency over time.

Steel: Steel is naturally more conductive than timber, so the energy efficiency of steel French doors depends heavily on their construction. Modern systems can use thermally broken frames, insulated glazing and high-quality seals to reduce heat transfer and improve overall performance. 

AluClad: AluClad French doors can offer excellent thermal performance thanks to their timber construction, which provides natural insulation, combined with protective aluminium cladding on the exterior. When paired with energy-efficient glazing and effective seals, they can help reduce heat transfer and maintain a comfortable indoor temperature. While exact performance will depend on the specification of the individual door system, AluClad French doors are the most energy efficient. 

In practice, frame material alone does not determine energy efficiency. Glazing, seals, installation quality and the door’s overall U-value provide a more reliable indication of how well French doors will retain heat.

Which French Door Material Is Most Durable?

uPVC: uPVC is resistant to rot, corrosion and most weather-related damage, making it a durable choice for everyday residential use. Over long periods, lower-quality frames can become discoloured or distorted, particularly with heavy exposure to sunlight and changes in temperature.

Aluminium: Aluminium is one of the most durable French door materials. It is strong, resistant to corrosion and unlikely to warp or swell, making it well suited to exposed locations and larger door openings.

Timber: Good quality timber French doors can last for decades, but their longevity depends more heavily on maintenance. Regular painting, staining or sealing helps protect the wood from moisture, rot and weathering.

Steel: Steel French doors are known for their strength and can provide excellent long-term durability when properly manufactured and protected. Suitable coatings and finishes help protect the steel against corrosion and weathering, making them a robust option for external use. 

AluClad: The combination of timber and aluminium means AluClad French doors are designed to be extremely durable. The external aluminium cladding helps protect the timber frame from rain, UV exposure and harsh weather conditions, reducing external maintenance and helping extend the lifespan of the doors.

Which French Door Material Requires the Least Maintenance?

uPVC: uPVC requires very little routine maintenance. Frames can usually be kept clean with occasional washing, while hinges, locks and seals should be checked periodically to ensure they continue working correctly.

Aluminium: Aluminium is low maintenance. Powder-coated frames generally only require occasional cleaning and do not need painting or staining, although moving components should still be inspected and maintained.

Timber: Timber requires the most ongoing care. Depending on the finish and exposure to the weather, doors may need periodic repairing, staining or resealing to prevent moisture damage and maintain their appearance. Internal timber French doors will require less maintenance, though, which is why the material is more popular for internal use.

Steel: French doors constructed from steel can also be relatively low maintenance when they have been properly treated and finished. Protective coatings help prevent corrosion, but the frames should still be cleaned and checked periodically for damage that could expose the underlying steel. 

AluClad: This composite material is very low maintenance because the external aluminium cladding protects the timber frame from exposure to the weather. Unlike exposed timber, the aluminium exterior doesn’t usually require regular painting or staining, although occasional cleaning and basic upkeep are still recommended.

For homeowners prioritising minimal ongoing maintenance, uPVC, aluminium and many composite systems generally require less maintenance than timber.

Which French Door Material Is Best For Security?

uPVC: Modern uPVC French doors can provide good security when combined with reinforced profiles, secure hinges and multipoint locking systems. The quality of the complete door system is more important than the uPVC material itself.

Aluminium: Aluminium’s inherent strength allows manufacturers to create rigid, robust frames, making it a strong starting point for secure French doors. However, suitable locks, glazing and hardware are still essential.

Timber: Solid timber frames can be extremely strong and secure when properly constructed. Their performance depends on factors including timber quality, frame condition, hinges and the locking system fitted.

Steel: Naturally strong and rigid, steel is a particularly good choice where security is a priority. Steel frames can withstand significant force, while modern systems can also include multi-point locks, reinforced hinges and toughened security glazing. This combination of frame strength and secure hardware can make steel doors highly resistant to forced entry. 

AluClad: Composite construction can provide a strong and rigid door structure by combining materials with different performance characteristics. The robust timber frames and the aluminium exterior creates an incredibly strong door system, and adding security glazing can only further improve resistance and security. 

When comparing security, look beyond the material. Multipoint locks, reinforced hinges, secure glazing, frame construction and professional installation all contribute to how resistant a French door is to forced entry.

How Much Do Different French Door Materials Cost?

uPVC: Generally, uPVC is the most affordable of the four materials, making it popular for homeowners looking for a practical option at a lower initial cost.

Aluminium: Aluminium French doors typically sit at a higher price point than uPVC. The additional cost is down to the material, manufacturing process, slim-frame designs and higher-specification finishes.

Timber: Timber prices vary considerably depending on the type, construction and finish. Engineered or premium hardwood doors can cost substantially more than standard uPVC systems, while ongoing maintenance should also be considered.

Steel: Steel French doors also tend to sit at the higher end of the market, particularly when they are bespoke or use thermally broken frames and specialist glazing. Price will depend on the size, frame design, finish, glazing and security specification. The higher price will be worth it if you’re after French doors with a distinctive appearance and high strength. 

AluClad: Composite AluClad French doors generally fall towards the premium end of the market because they combine the benefits of timber and aluminium. Like all these options, costs can vary depending on specifics like the timber species, glazing, dimensions, finish and hardware selected. Their higher initial cost may be offset by strong thermal performance and relatively low external maintenance over time. 

The final cost can change considerably depending on door dimensions, glazing, colour and finish, hardware specifications, condition and whether it’s brand new or pre-owned.

How To Choose The Best French Door Material For Your Home

Budget: If you’re conscious of price, uPVC and aluminium French doors are typically the most cost-effective and have lower upfront costs.

Property style: uPVC, aluminium and composite are all suitable for contemporary home designs, while timber and steel offer a more traditional aesthetic and are often chosen to complement older properties.

Security: All modern French doors offer great security, as long as they’re fitted with sufficient locking systems and strong glazing.

Maintenance: uPVC, aluminium and composite materials are all very low maintenance. Timber may require more frequent and long-term maintenance, such as repainting or resealing.

Energy efficiency: Modern designs mean that all materials are very energy efficient and help keep comfortable indoor temperatures. The slim frames of aluminium doors do mean that other materials may be slightly better in this regard, but ALuClad still offers the best in terms of thermal efficiency, even with the slim lines.
