Warranty

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. 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™ films (or 3M™ 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

There is a consumer deductible of $25.00 (or 5% of the replacement cost, whichever is greater) per claim.
Any glass failure covered by this warranty must be reviewed by Seller prior to repair, and only covers film and glass replacement.

Optional Platinum Warranty - Residential Applications Only
The 3M Platinum Warranty matches the terms and conditions of the residential customer's existing window manufacturer's warranty for a mere $.35/square foot. This allows the customer continuous coverage on new windows and the peace of mind having assurance that a product from 3M is protecting their investment.

Do 3M™ Window Films cause glass to break?

The application of 3M™ will increase the temperature of your sunlit glass which will increase the stress on the glass edges. The quality of those glass edges and several other factors (external shading, interior shading, glass history, type of film, size/shape of glass, indoor/outdoor temperature) all contribute to the potential risk of glass breakage.

3M's thirty (30) years of experience with applying 3M™ Window Films to different types of glass enables us to make proper film/glass recommendations and minimize the potential for glass breakage. In addition, we support these recommendations with our 60-month glass breakage warranty against thermal shock fracture. Should the glass break within 60-months of application, 3M; will replace the glass (maximum $500.00 with a $25.00 consumer deductible, or 5% of replacement cost, whichever is greater per claim), and the dealer will replace the film.

Do 3M™ Window Films cause seal failure when applied to insulated (double-pane, Thermopane™) windows?

No, 3M™ Window Films do not cause seal failure. We've been applying 3M™ films to insulated windows for over 30 years with several millions of square feet of film applied to date.

When recommended films are applied to the inside pane of an insulated glass unit, there will be some absorption (except with clear safety films) of the sun's energy, which will increase the temperature of the glass pane. Some of this heat will transmit to the airspace, slightly raising the airspace temperature. However, even a 20 F degree increase (unusual for most films) will result in a less than 3% change in air pressure, whereas properly made units are designed and tested to withstand 22% changes in air pressure.

Risk of seal failure is greatly determined by the quality of workmanship and the quality of the materials that go into building the insulated glass units. The best guard against seal failure is to purchase well-made units from reputable window manufacturers that have solid experience and histories with insulated units.
