BIFORIUM / GUIDE
ALUMINIUM OR PVC
For a small standard window, a strong PVC system may be more rational. For slim frames, large sashes, façades and heavy sliders, aluminium usually offers greater structural freedom.

Aluminium and PVC solve different problems. Size, proportions, finish, budget, thermal design and opening type matter more than a universal answer.
Start with geometry
Sash width and height, mullions, glass mass and wind action quickly exclude unsuitable platforms.
Compare real finishes
Foil, powder coating, anodising and dual-colour configurations look and age differently.
A house can use both
PVC in standard rooms and aluminium in the panoramic zone can be a technically honest balance.
