Heat Shrinking

With rear windows today, automotive window film installers are facing more glass, more curves and more challenges than ever before. Understanding how to handle various types of rear windows sets the good installer apart from the rest. This section will provide the basic techniques to get you started. Remember, practice as much as possible if you are new to rear windows. Start with the easier cars. You are going to make mistakes in the beginning but it will get easier with every window you work on. Practice. It will get easier.

There are 2 basic techniques to make window film (which is flat)
fit onto a car rear window (which
is curved). The original method
is called Strip & Splice while the newest technique is Heat Shrinking (a.k.a. Heat Shaping).

Most cars today are done with using the 1 piece Heat Shrink method. The film is "shrunk" to fit the curve of the rear window with a heat gun. It provides the cleanest look to a finished window and it's also a faster method once you have mastered the technique.

The Strip & Splice method should be used when you are not able to heat shrink—if you
are not near an electrical outlet or in an emergency situation when the power goes out. This technique can leave visible splice lines across a finished window (which is why most installers prefer heat shrinking) because you install multiple strips. However, for mobile installers, the Strip & Splice method can be a lifesaver.
