Alu doors and windows are lighter than PVC and as such are suitable for glazing larger surfaces, like glass facades but also office spaces.
They fulfil all aesthetic requests with their appearance and great selection of colours, and their smooth surface and perfect finishing make it very easy for maintenance. It can be adjusted to openings of all sizes, even nonstandard ones. Aluminium is a metal, and like all metals it is a good heat conductor, so its insulating properties are considerably worse than those of PVC. However, modern aluminium doors and windows are produced with a thermal break (thermal bridge) which has significantly improved its thermal and acoustic properties.
