Window film is extremely durable. After all, it has to with- stand constant abuse from the sun, day in and day out. This is not to say that eventually all window film will not fail, it will eventually corrode and need replacing. The life-span is long and we at ClimatePro have seen residential installations that are approaching 20 years from the original installation date. Only a few windows from these installations needed replacing under warranty. Window film also comes with a scratch resistant clear coating of the top surface, protecting the window film scratches over the years.
