Yes — aluminium bifold doors are generally worth the additional cost over uPVC for many applications, but whether they’re worth it for you depends on your priorities, budget, and how you’ll use the space.
🧱 1. Strength & Performance
Aluminium
• Much stronger and stiffer than uPVC.
• Allows larger panels and wider openings with slimmer frames.
• Ideal for floor to ceiling glass walls and open indoor–outdoor living.
uPVC
• Frame profiles are bulkier for similar strength.
• Maximum panel size is more limited.
⟶ Winner: Aluminium for large, modern openings.
☀️ 2. Aesthetics & Modern Design
Aluminium
• Sleek, narrow sightlines for a high end, contemporary look.
• Wide range of finishes (including anodised and textured colours).
uPVC
• Thicker frames and more limited colour/finish options.
• Can look less premium in modern architecture.
⟶ Winner: Aluminium for architectural impact.
🧠 3. Thermal Efficiency
uPVC
• Naturally better thermal performance due to material properties.
Aluminium
• Needs a thermal break (insulated core) to match uPVC’s performance.
• With proper thermal breaks and glazing, aluminium can be energy efficient too.
⟶ Tie: Provided aluminium units are well made with thermal breaks.
🔒 4. Longevity & Durability
Aluminium
• Extremely durable: won’t warp, rot, fade, or crack.
• Handles wide temperature swings and coastal conditions very well.
uPVC
• Durable, but can discolour or distort over time in extreme heat.
⟶ Winner: Aluminium for long term performance.
🛠 5. Maintenance
Aluminium
• Very low maintenance — cleans easily and doesn’t need repainting.
uPVC
• Also low maintenance but more prone to marks and fading over time.
⟶ Tie: Both are low maintenance, but aluminium stays looking sharp longer.
🏷 6. Cost
uPVC
• Generally less expensive upfront.
Aluminium
• Higher initial cost — typically 20–50%+ more, depending on size, hardware, and finishes.
⟶ Winner: uPVC for upfront affordability.
🏡 7. Value & Resale
Aluminium Bifolds are often perceived as premium features in modern homes. They can:
• Increase curb appeal
