Salamander bluEvolution 82

  • superior thermal performance
  • the best value for the money

  • create custom, high-end designs

Why uPVC — and when to consider other options

uPVC windows are often the go-to solution for cost-effective builds. But they’re not always the best fit — especially in projects requiring premium aesthetics or ultra-thin frames.

For high-end projects that require:

  • maximum durability,
  • slim profiles,
  • luxury design,
  • or large glazing panels,

aluminum windows may be a better option than PVC.

If that sounds more like your situation, check our ranking of the best aluminum windows.

The best triple-pane uPVC windows

The most energy-efficient uPVC windows with the best quality-to-price ratio are Salamander bluEvolution 82. 

Salamander has left the competition far behind, all thanks to its:

  • reasonable price
  • great thermal parameters
  • NFRC-certification

Suggested alternatives

For a thinner profile at a better price, choose Aluplast Ideal Neo.

Gealan Linear and Gealan S9000 offer the same sash and frame height but are more expensive than Ideal Neo.

For an aluminum-like look, consider Aluplast Ideal Neo or Gealan Linear

Both are commonly used in projects that combine uPVC and aluminum windows to maintain a consistent design—and both performed very well in our Aluminum-look uPVC windows ranking.

Don’t miss that! Triple-glazed uPVC Windows: Ranking Methodology

If you’re familiar with windows and the European window production chain, you know that even the best window system, if assembled by the wrong manufacturer, can lead to installation issues, delays, and extra costs.

That’s why our ranking focuses on profiles offered by Polish manufacturers vetted by us.

  • We’ve also been in your shoes—buying windows as a customer.
  • Over more than 10 years, we’ve placed thousands of orders across Poland.
  • This hands-on experience allows us to compare not only the profiles themselves, but also how different manufacturers assemble and deliver them.

What did we compare in the ranking?

The debesto team evaluated the most energy-efficient European uPVC windows from top brands: Aluplast, Decco, Gealan, Rehau, Salamander, Schüco, and Veka.

We also factored in how each product impacts your bottom line, along with real-world feedback from our customers.

All windows in the ranking meet the following specifications:
