Before you choose the appropriate film you need to ask yourself what the main problem is – is it anti-burglary protection, or is it too warm, is the sun blinding you, is someone looking in through the window, do you need some privacy in the room, or do you need to give your car windows or panes a different character, and consequently the entire exterior of the building.
Further questions are whether the windows are new or several years old, is there argon between the panes, are the panes made of low-emission glass, are they coloured, do they have two or more window panes, what are the window frames made of – PVC, aluminium or wood?
