3M has a residential limited lifetime quality promise. The warranty applies to the purchaser as long as he/she lives and owns the home. It can not be transferred to the next owner. The warranty for the 3M Sun Control Window Film promises to:
- Keep its solar reflective properties without cracking, crazing, or peeling
- Keep its adhesion properties without blistering, bubbling, or delaminating from the glass
- Keep its appearance without discoloration
If the product is found to be defective under the warranty, 3M will:
- Replace the quantity of film that is defective
- Provide removal and reapplication with the labor being free of charge
The 3M residential warranty is also for glass failure due to thermal shock fracture or seal failure for up to $500 per window. The glass failure would need to be a result of the application of 3M Sun Control Film as long as the film is applied to the recommended types of glass and the glass failure is reported to the Seller within the specified time from the start of the installation. See specific warranty for these time frames.
Glass failure covered by this warranty must be reviewed by the Seller prior to repair, and only covers film and glass replacement.
A claim is made to the dealer from whom the film was purchased or to 3M.
The warranty is void if the product has been given improper care such as the use of abrasives to clean the window. The care recommendations are sent to the purchaser and is also at the bottom of the warranty information. The care instructions are also in a previous Solar Vision blog and/or is easily found on the Internet. (solutions.3m.com)
In comparing other window film warranties to the 3M residential warranties, most are similar to each other. As far as I could find, none surpass the 3M warranty. 3M has a reputation of standing behind their products. You can trust the 3M brand.
