Aluminium Sliding Doors vs. Wooden and Timber

Author: John Collins - Managing Director

Sliding doors are a popular choice for UK homes, particularly for patios, gardens, and open-plan extensions where maximising light and space is a priority. Among the many materials available, aluminium and wooden sliding doors are the most commonly compared. Each has its own strengths depending on your budget, design preferences, and long-term expectations.

Are Aluminium Sliding Doors Better Than Wooden Doors?

Whether aluminium sliding doors are “better” than wooden ones depends on what you value most: durability, aesthetics, maintenance, or cost.

Feature	Aluminium Sliding Doors	Wooden / Timber Sliding Doors
Durability	Extremely durable; resistant to warping, rot, and corrosion	Durable but vulnerable to moisture, rot, and movement over time
Maintenance	Very low; occasional cleaning only	Moderate to high; requires painting or staining
Aesthetics	Sleek, modern, minimalist	Warm, natural, traditional or contemporary
Frame Thickness	Slim frames allow larger glass panels	Thicker frames reduce visible glass area
Energy Efficiency	High with modern thermal breaks	Naturally insulating
Lifespan	30–45 years or more	20–40 years depending on care
Customisation	Wide range of colours and finishes	Highly customisable in shape and finish
Environmental Impact	Highly recyclable	Renewable material if responsibly sourced
Cost	Mid to high	Mid to high (often higher for hardwoods)

What Factors Affect the Lifespan of Wooden and Aluminium Sliding Doors?

The lifespan of sliding doors is influenced by several factors, not just the frame material. To make a more informed decision and extend the life of your investment, consider these factors before making your choice:

Climate and Exposure: in the UK’s damp and often unpredictable climate, wooden doors are more susceptible to warping and rot if not properly protected. Coastal locations can increase wear, especially where salt air is present. Aluminium, by contrast, is highly resistant to moisture and corrosion, making it ideal for exposed or coastal areas.
Quality of Materials: not all aluminium or timber doors are equal. High-quality aluminium systems use advanced powder coatings and thermal breaks, while premium timber doors rely on slow-grown hardwoods or engineered wood for stability. Cheaper materials often result in a shorter lifespan regardless of type.
Manufacturing and Installation: precision manufacturing and professional installation are critical. Poor alignment, inadequate drainage, or substandard seals can shorten the lifespan of both wooden and aluminium sliding doors.
Maintenance Routine: wooden doors can last decades if regularly maintained, but neglected timber deteriorates quickly. Aluminium doors are far more forgiving, retaining their structure and appearance with minimal upkeep.
Usage Patterns: frequently used patio doors experience more wear on tracks, rollers, and seals. Aluminium systems typically handle heavy use better due to their strength and rigidity.

Which Option Requires Less Maintenance: Aluminium or Timber?

Aluminium sliding doors are the clear winner when it comes to low maintenance.

Aluminium Sliding Doors

Require only occasional cleaning with soapy water
Powder-coated finishes resist fading and peeling
Do not warp, rot, or need repainting
Hardware components are long-lasting and robust

Wooden and Timber Sliding Doors

Need regular painting, staining, or oiling (typically every 3–5 years)
Vulnerable to moisture if coatings fail
May require repairs to address cracks or rot
Ongoing care is essential to preserve appearance and performance

For homeowners seeking a long-lasting, stylish entryway to their home, aluminium sliding doors are significantly more convenient. Timber doors suit those who enjoy the upkeep or value the aesthetic enough to justify the effort.

What Design Options are Available for Wooden and Aluminium Sliding Doors?

Both materials offer extensive design flexibility, though they differ in how that flexibility is achieved.

Aluminium Sliding Door Design Options

Ultra-slim frames for maximum glass and light (our COR Vision ultra-slim aluminium patio doors are the perfect option, with uninterrupted views and a seamless transition from outdoor to indoor).
Large panels suitable for wide openings
Contemporary colours, including anthracite grey, black, and white
Dual-colour options (different colours inside and out)
Modern architectural styling ideal for extensions and new builds

Aluminium is especially popular in minimalist and modern homes, where clean lines and expansive glazing are key design features.

Wooden and Timber Sliding Door Design Options

Natural grain patterns for a unique appearance
Choice of softwood, hardwood, or engineered timber
Traditional or heritage designs for period properties
Painted, stained, or varnished finishes
Custom shapes and detailing

Timber doors offer a tactile, organic feel that aluminium cannot replicate, making them a favourite for cottages, listed buildings, and character homes.

Frequently Asked Questions

What are the Main Differences Between Wooden and Aluminium Sliding Doors?

The main differences lie in durability, maintenance, and appearance. Aluminium doors are stronger, require less upkeep, and suit modern designs, while wooden doors offer natural beauty, warmth, and traditional appeal but need more regular maintenance.

Are Wooden or Aluminium Doors Better for Patio Doors?

Aluminium doors are generally better for patio doors due to their slim frames, ability to support large glass panels, and resistance to weather. Wooden doors can work well for patios in sheltered locations or where a traditional aesthetic is desired.

How Does the Price of Aluminium Sliding Doors Compare to Wooden?

Prices are often comparable, though aluminium doors may be slightly more affordable than high-end hardwood options. Over time, aluminium can be more cost-effective due to lower maintenance and longer lifespan.

Are Engineered Wooden Doors a Good Alternative to Aluminium?

Yes, engineered wooden doors are a strong alternative. They offer the appearance of solid timber with improved stability and reduced risk of warping. However, they still require more maintenance than aluminium.

Which Material is More Energy Efficient for Patio Doors: Wood or Aluminium?

Both can be highly energy efficient. Wood is naturally insulating, while aluminium doors rely on thermal breaks and high-performance glazing. With modern systems, the difference in energy efficiency is usually minimal.
