Torn between PVC or aluminium window frames? Both materials are excellent, but they differ in price, looks and application. This comparison helps you choose.
PVC window frames: the advantages
PVC window frames are energy-efficient, virtually maintenance-free and very competitively priced. They are available in any colour (including wood-look) and offer excellent insulation — ideal for home improvement.
Aluminium window frames: the advantages
Aluminium window frames are slim, strong and sleek. Thanks to the thin profiles you get more glass and more daylight — perfect for modern architecture and large sliding doors.
The comparison at a glance
- Price: PVC is more economical; aluminium somewhat more expensive.
- Insulation: both very good; PVC insulates by nature, aluminium with a thermal break.
- Maintenance: both low-maintenance.
- Lifespan: both 30+ years.
- Looks: aluminium slimmer and more modern; PVC versatile in colour.
- Large glass surfaces: aluminium is the best choice here.
Which one should you choose?
Looking for the best value for money and top insulation? Then PVC is often ideal. Want sleek, large glass surfaces with a modern look? Then we recommend aluminium. We often combine both materials in one home.
