Approximately 1 out of every 5,000 windows will ever experience a warranty issue with Precision Film and Solar Shades. We have found that if the proper window film is installed, the window tint will not sacrifice the integrity of the window. You have to take into account the shading, panes of glass, altitude and so forth, in order to know what window tint would work best. Our trained sales people know what film should be installed on certain windows as to avoid any issues.
