What's better uPVC or aluminium patio doors?
Whether uPVC or aluminium patio doors are “better” depends on your priorities (budget, performance, appearance, lifespan). Below is an objective comparison to help you decide:
🧱 1. Strength & Size of Glass Panels
Aluminium
• Stronger material → allows slimmer frames and larger glazed areas
• Ideal for wide openings and expansive views.
uPVC
• Less rigid → frames are thicker for strength
• Limits large panel sizes.
🏆 Winner: Aluminium (for modern, expansive designs)
🎨 2. Aesthetics
Aluminium
• Sleek, minimalist profiles
• Wide colour options (anodised, textured, bespoke tones)
• A premium, contemporary look.
uPVC
• Typically thicker profiles
• Colour options available (including foils), but less refined
• Suits traditional as well as modern homes but looks less high end.
🏆 Winner: Aluminium (most design flexibility/appeal)
🌡 3. Thermal Performance
uPVC
• Naturally good insulator due to material properties
• Often performs very well with standard double glazing.
Aluminium
• Conducts heat more easily → needs a thermal break to improve insulation
• With thermal breaks and good glazing, thermal performance can match or exceed uPVC.
🏆 Winner: Tie — but only if aluminium has a thermal break and quality glazing
🛠 4. Durability & Maintenance
Aluminium
• Exceptionally durable and long lasting
• Doesn’t warp, rot, or corrode (excellent for coastal environments)
• Simple cleaning is usually all that’s needed.
uPVC
• Durable and low maintenance
• May discolour, sag, or distort over long periods in extreme heat
🏆 Winner: Aluminium (for longevity and stability)
🔒 5. Security
Aluminium
• Rigid frames handle high security hardware very well
• Tough and resistant to forced entry
uPVC
• Good security when well reinforced
🏆 Slight Advantage: Aluminium
💰 6. Cost
uPVC
• Lower upfront cost
• Excellent value for standard projects
Aluminium
• Higher initial cost (materials + fabrication)
• Typically 20–50% more expensive than uPVC
🏆 Winner: uPVC (for cost)
🌍 7. Environmental Impact
Aluminium
• Highly recyclable
• Long lifespan reduces need for replacement
uPVC
• Recyclable
🏆 Winner: Aluminium (often better environmentally long term)
