How to avoid thermal fractures
Method 1: If you used the appropriate film for a dual-paned window, the thermal crack may not be your fault. Instead, the fractures may be because of a slight chip or nick in the glass that weakens it. Thermal fractures usually ‘meander’ through the glass in multiple directions. If the crack is in a straight line, it’s more likely from the impact of something. If a customer complains about a crack, you can try just replacing it. Then, you can try to get the manufacturer to reimburse you.
