3M Window Films are made to last for many years. The exact length of time depends upon the type of film applied, window orientation, type of glass it is applied to and the particular climate in which it is applied.
Most applications last well beyond the warranty length.
3M Window Films are warranted to maintain their solar properties without bubbling, peeling, cracking, or crazing. Many of our films are warranted against discoloration, too. (Those which do not use dyed polyesters). Should the product proved to be defective, 3M and the authorized 3M Dealer will replace the film and provide the reapplication labor free of charge.
Seller also warrants against glass failure due to thermal shock fracture or seal failure (maximum value of $500 per window) caused only as a direct result of the application of 3M Window Films provided the film is applied to recommended types of glass and the glass failure is reported to the seller within the specified time (listed below) from the start of the installation.
