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

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

Suggested alternatives
For a thinner profile, choose Aluplast Ideal Neo.
Gealan Linear and Gealan S9000 offer the same sash and frame height but are more expensive than Ideal Neo.
See the real-life project with 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.

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 12 years, we’ve placed thousands of orders across Poland.
