Aluminium Vs. uPVC for Doors & Windows – Which One is Better & Why?

Enough of Confusion – Let’s Get Real

You’ve seen 100 blogs say “aluminium vs uPVC“, but which aluminium? Not every metal with a shiny face is door-worthy. Comparing aerospace-grade Aluminium 7075 to window-grade uPVC? That’s like comparing a fighter jet to your living room fan.

So let’s stop the confusion. This comparison is between Aluminium 6063 (or 6060)—used in windows and doors—and uPVC (Unplasticized Polyvinyl Chloride). No marketing jargon. No “it depends”. Just facts that help you pick the right frame for your home or project—whether you’re in Delhi or Devon.

Material Showdown: Strength Meets Style

✅ Aluminium 6063 – The Tough Customer

Used in: High-quality door/window frames, curtain walls, façades

Battle of Strength

Who Lasts Longer?

Aluminium 6063: Built for long-term use. Zero rust, minimal expansion/contraction. Add a thermal break and it handles weather like a champ.
uPVC: Resistant to environmental damage, but plastic can crack or fade over time under intense sun or cold.

🎯 UK tip: If you live in a coastal town, go for powder-coated or anodized aluminium.
🎯 India tip: In hot & dusty regions, aluminium wins hands-down on endurance.

Thermal Performance

uPVC’s Time to Shine

Aluminium (without thermal break): Higher conductivity = more heat/cold transfer
Aluminium (with thermal break): Matches or beats uPVC in insulation
uPVC: Lower conductivity by default. Great for energy savings.
