Aluminium and PVC windows: useful guidance for choosing well

Choosing aluminium and PVC windows is not only a matter of price. In every home, orientation, climate, outside noise, opening size, façade design and daily use all influence the final decision. Cortizo Windows brings together solutions designed to improve thermal insulation, acoustic insulation, security, natural light and energy efficiency while preserving the character of each project.

Aluminium stands out for its strength, durability, dimensional stability and design possibilities, especially when large openings, slim profiles or highly customised finishes are required. PVC offers excellent insulating performance, low maintenance and a strong balance between comfort and value for home renovation. In both cases, the right choice should take into account the glazing, opening type, installation quality, orientation and the real needs of the household.

Beyond comparing materials, it is useful to define what needs to be improved: reducing energy loss, gaining more silence, increasing security, simplifying maintenance, renewing the appearance of the home or preparing it for more efficient consumption. The Cortizo Windows retail network helps assess each project, identify the most suitable solution and request a professional quotation for replacing windows with a close, project-focused service, without spam or unrelated calls.
