Thermal performance: aluminum and uPVC at equivalent levels
Choosing between aluminium vs uPVC windows is a key step in any construction or renovation project. At VST , specialists in high-performance European doors and windows , we offer both solutions with a clear observation: the difference in thermal performance between aluminium and uPVC is now minimal .
The choice depends primarily on the architectural design , the size of the openings , the budget and aesthetic preferences .
Thermal performance: Aluminum vs. uPVC at equivalent levels

Triple glazing and enhanced insulation
Our door and window systems offer:
Thermal performance from Uw ≤ 0.6 with triple glazing
Excellent air and water tightness
High sound insulation
Optimal comfort for cold and temperate climates
👉 Conclusion : climate is no longer a decisive factor between aluminium windows and uPVC windows when the systems are high-end.
Opening dimensions: a determining factor
