3MTM 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, 3MTM and the authorized 3MTM 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 3MTM 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.

  • Sixty (60) months coverage against thermal shock fracture
  • Forty (40) months coverage against seal failure if covered by original window manufacturer

Any glass failure covered by this warranty must be reviewed by Seller prior to repair, and only covers film and glass replacement.
