The Difference Between uPVC and Aluminium Sliding Patio Doors
On the surface, sliding patio uPVC doors and aluminium ones serve the same purpose: they open up your living space and let the light flood in. But what sets them apart is what they’re made of—and that difference can have a big impact on performance, longevity and the feel of your home.
uPVC (Unplasticised Polyvinyl Chloride) is a plastic material that’s affordable and widely used. Aluminium, on the other hand, is a strong, sleek metal that brings durability and minimalism in equal measure.
Short-Term Savings vs Long-Term Value
Sure, cheap uPVC sliding patio doors can be tempting, especially if you’re renovating on a tight budget. They’re relatively inexpensive to buy and fit—but that short-term saving could cost you more in the future.
Aluminium doors, like our Smart Visoglide or Korniche Cortizo 4700 systems, offer a far longer lifespan. They’re less likely to warp, discolour or break, and they stand up better against the elements over time. When you weigh up replacement costs, ongoing maintenance, and potential energy losses, aluminium becomes a clear long-term investment.
Strength, Style & Size: Why Aluminium Has the Edge
uPVC is lightweight, which is handy—but that also means it can’t support large panes of glass. If you’re dreaming of large uPVC sliding patio doors, you’ll hit a limit fast.
Aluminium doors can handle much bigger sizes without compromising on structural integrity. You’ll get a wider opening, more natural light, and the all-important wow factor. Plus, their slim sightlines and sleek aesthetics fit seamlessly into modern and traditional homes alike.
Aesthetics and Colour Choices
Let’s be honest—white uPVC is common, and in many cases, uninspiring. While some colour options exist, they often involve laminated foils that can peel or fade over time.
Aluminium? A totally different story.
You can choose from hundreds of colours, including anthracite grey aluminium, and finishes from matte to metallic, smooth to textured. Dual-colour options even let you match your interior décor on one side and your exterior style on the other. That’s something black uPVC sliding patio doors or brown uPVC sliding patio doors simply can’t deliver with the same finesse.
Maintenance & Durability
One of the most common issues with fitting uPVC sliding patio doors is long-term performance. They tend to expand and contract with temperature changes, which can lead to dropping, draughts, and sticky operation.
Aluminium, on the other hand, is far more dimensionally stable. It’s rust-resistant, doesn’t degrade in sunlight, and never needs repainting. Just a quick wipe-down every now and then and you’re good to go.
Even the uPVC sliding patio door lock replacement process can become a headache, whereas aluminium doors often come with integrated, high-security multi-point locking systems tested to PAS24 standards.
Cost Considerations: Cheap uPVC Sliding Patio Doors vs Aluminium
Let’s address the elephant in the room—price.
Yes, aluminium sliding doors cost more upfront. But think about what you’re actually paying for:
- Longer lifespan
- Better energy efficiency
- Lower maintenance
- Improved aesthetics
- Higher property value
When you add it all up, aluminium represents better value for money. That’s especially true if you want something like anthracite grey uPVC sliding patio doors but don’t want to compromise on door colour, stability or frame size.
