Aluminium vs uPVC Patio Doors: Which Should You Choose?

Choosing between aluminium and uPVC patio doors comes down to the look you want, the size of the opening, security, thermal performance and how you use the space. Both options from Tower Windows provide smooth sliding operation, large areas of glass and practical garden access, but each material has different strengths.

What Is the Main Difference Between Aluminium and uPVC Patio Doors?

The main difference lies in the frame material and the design possibilities it offers. Aluminium is naturally strong, allowing us to offer slim sightlines and large glazed panels. uPVC patio doors use multi-chambered profiles designed to combine strength, insulation and everyday practicality.

Both styles slide rather than swing open, so they do not require the clearance associated with French doors. This makes aluminium and uPVC patio doors useful for wide openings and spaces where you want to preserve usable floor or patio space.

Why Choose Aluminium Patio Doors?

Aluminium patio doors are ideal if you prioritise slim frames, expansive glazing and contemporary styling. Our aluminium patio doors use durable, powder-coated frames with large glass panels to create wide views and a bright, open feel. Their slim profiles reduce the amount of visible frame, which can make aluminium particularly attractive for modern extensions and open-plan living spaces.

Security features include multi-point locking and toughened safety glass, with PAS 24 upgrade options available. Double or triple glazing can also be specified to improve insulation, while the colour range includes Anthracite Grey and Chartwell Green.

Aluminium may suit you if you want:

• Slim sightlines and more visible glass
• Durable, powder-coated frames
• A contemporary appearance
• Optional triple glazing
• PAS 24 upgrade options

Why Choose uPVC Patio Doors?

uPVC patio doors are a practical choice for homeowners who value thermal efficiency, flexible configurations and secure sliding operation. Tower Windows uPVC patio doors use multi-chambered profiles and 28mm double glazing as standard, with U-values available as low as 1.0 W/m²K.

Homeowners can choose 2, 3 or 4 sliding panes, with a triple-track 6-pane option for larger openings. Security features include a 6-point hook locking system and anti-lift brackets.

A thermally broken low threshold is also available in black or white, helping improve accessibility for pushchairs or wheelchairs while supporting insulation.

uPVC may suit you if you want:

• Strong thermal performance
• 2, 3, 4 or 6-pane configurations
• A low-threshold option
• 6-point hook locking and anti-lift protection
• Chamfered or ovolo sash styles

Which Is Better for Energy Efficiency?

Both aluminium and uPVC patio doors can provide good thermal performance. The uPVC patio doors can achieve U-values as low as 1.0 W/m²K. The aluminium range is available with advanced double or triple glazing to improve insulation and indoor comfort. If energy performance is your main priority, compare the exact frame and glazing specifications before deciding.

Which Patio Door Offers Better Security?

Both options include substantial security features, so the best choice should be based on the exact specification. Aluminium patio doors include multi-point locking and toughened safety glass, with PAS 24 upgrades available, while uPVC patio doors use 6-point hook locking and anti-lift brackets.

Homeowners prioritising security should compare the locking system, glazing and optional upgrades available for their chosen configuration.

Which Looks Better: Aluminium or uPVC?

Aluminium patio doors generally create a slimmer, more contemporary appearance because aluminium’s strength allows narrower frames around large glazed panels. uPVC patio doors provide a more traditionally framed look while still offering slim sightlines and generous glazing.

Your choice should complement the rest of the property. Aluminium may suit modern extensions and minimalist interiors, while uPVC can integrate naturally with homes that already feature uPVC windows and doors.

Aluminium vs uPVC Patio Doors: Which Should You Choose?

Choose aluminium patio doors if slim frames, expansive glazing, contemporary styling and colour choice are your priorities. Choose uPVC patio doors if you value clearly specified thermal performance, flexible pane configurations and practical options such as a low threshold. There is no single winner in the aluminium vs uPVC patio doors comparison. The right choice depends on your home, opening size, design preferences and performance requirements.
