3M™ window film warranty · terms by film, registered by Epic
The warranty is 3M’s. Keeping it valid is ours.
Every film Epic installs is a genuine 3M product with a published 3M warranty behind it. Here is what it covers, how long it runs on each film, what voids it, and what Epic does on every job so it holds up when you need it.
- Residential: lifetime of the original owner
- Commercial: 10 to 15 years, by film
- Registered with 3M by Epic within 30 days
Four warranties, one document.
3M publishes one bulletin for every flat-glass window film it makes. It bundles four separate promises, and the one most buyers never hear about — glass breakage — is the one that matters most to a facilities director.
Performance
The installed film will adhere without blistering, cracking, peeling, bubbling, lifting, curling or delaminating, and will hold its clarity and color without discoloration, excessive fading or loss of reflectivity. The attachment sealant, where applied, keeps its bond without cracking or peeling. Runs for the period in the table below.
Glass thermal shock
If a pane breaks from thermal stress as a direct result of the film, 3M reimburses replacement glass and labor up to $1,500 per window residential and $2,000 per window commercial, for five years from installation. Requires a completed glass questionnaire at registration — which is why Epic checks glass type on every survey.
Seal failure
If your glass manufacturer voids its insulated-glass seal warranty because film was applied, 3M matches it, capped at the same $1,500 / $2,000 per window including labor, for 10 years residential or 3 years commercial. The manufacturer’s coverage is used first if it is still in force.
Basic product
The film and the attachment sealant conform to 3M’s manufacturing specifications on the day they were made. Removal is not a warranty item: film comes off, adhesive residue is expected, and the remedy for a confirmed defect is a refund or a replacement installed by a 3M-selected authorized dealer.
How long it runs, film by film.
Performance warranty periods from the current 3M bulletin. “Lifetime” on a residence means the lifetime of the original purchaser while they own and occupy the home; it does not transfer and does not cover rentals. Glass breakage coverage is five years and seal failure three years on every commercial film (ten residential).

Residential seal-failure coverage runs 10 years. Exterior-applied films carry fixed terms on residences too, and sloped glass shortens the exterior period as shown. For windstorm, break-and-entry and blast applications, and for single-pane tempered glass, 3M requires its attachment sealant on all four sides of the frame for the security film warranty to apply — the Epic Method installs it that way as standard.

DI-NOC and Fasara carry their own 3M terms.
Finishes are warranted under 3M’s Commercial Solutions documents rather than the window film bulletin, and the periods are shorter because the products do a different job: they are decorative surfaces in daily contact with people, carts and cleaning crews, not a film sealed against glass.
3M™ DI-NOC™ Architectural Finishes
Interior, vertical installations are warranted by 3M for 12 years against visual and adhesive defects, excessive fading or discoloration, cracking, yellowing and delamination — when installed by a 3M-certified DI-NOC installer on a properly prepared, sound substrate and maintained to 3M’s cleaning guidance. Exterior-rated EX series finishes carry shorter terms that vary by finish and exposure; Epic states the exact period on the proposal. Normal wear at high-traffic corners and edges is not a defect, which is why Epic specifies corner guards where carts live.
3M™ Fasara™ Glass Finishes
In the United States 3M warrants Fasara against significant discoloration, cracking and similar visual defects for 5 years on interior glass away from the building perimeter and 3 years on perimeter glass that sees direct sun; newer designs carry 3 years and 1 year respectively, the two black designs (Illumina Black and Opaque Black) 2 years, and the four exterior-rated frosts 3 years outdoors. Fasara is vertical-only — non-vertical applications are not warranted. Expected service life is longer than the warranty: 3M puts it at five to twenty years indoors depending on the design.
What keeps a finish warranty valid
- Certified installer. 3M trains and certifies DI-NOC installers through hands-on training; Epic’s Certified Installation Specialists hold it, which keeps the 3M warranty valid.
- Record of installation. Substrate, primer, finish codes and date, completed at closeout. Epic keeps it and gives you a copy.
- Fresh material. DI-NOC installed within its shelf life from a 3M-authorized supply; no lookalike film.
- 3M cleaning only. Neutral detergent and water, no solvents, scouring pads, bleach or steam. The care page has the full list.
- Report it in writing within 30 days of noticing a defect, before anything is removed or repaired.

A warranty is only as good as the paperwork behind it — and the bead under it.
3M’s bulletin is clear: coverage depends on the dealer doing specific things before, during and after the install. Most of the horror stories in our Buyer Beware file are installations where nobody did them.
Before: glass questionnaire
Glass type, construction, orientation and thermal-stress compatibility are recorded at the free survey. 3M will not honor a breakage claim without it. Epic has never recommended a film the glass could not take.
During: the system, complete
Genuine 3M film, 3M structural silicone attachment on all four sides where the application calls for it, precision-cut panels with no splices, installed by Epic-employed Certified Installation Specialists. No substitutions, ever — a non-3M attachment on 3M film voids the warranty outright.
After: registered in 30 days
Epic registers every installation in 3M’s eWarranty system within the 30-day window, with the questionnaire, proof of purchase and your glass manufacturer’s warranty attached. Miss the window and 3M’s coverage is void; we don’t miss it.
Closeout: certificate in hand
You receive the 3M warranty certificate and an opening-by-opening install record. Keep them with your proof of purchase and glass warranty — 3M requires all three for a claim — and Epic keeps a copy too.
Short list. Easy to stay on the right side of.
3M’s exclusions are the same for every film, and almost all of them come down to two things: putting something on the film that should not be there, or letting someone who is not an authorized dealer touch it.
- Ignoring the care guidelines. Coverage is conditional on 3M’s inspection, cleaning and maintenance guidance. No washing for 30 days; after that, glass cleaner, soft cloth, squeegee. The care page is the whole list.
- Adhesives on the film. Tape, stickers, decals, suction cups, hooks and Command™ strips. If you need numbers, frost or a decal on filmed glass, Epic prints a film-safe layer that goes on and comes off clean.
- Abrasion. Pressure washing, brushes, scrapers, scouring pads, sandstorms and tree branches on exterior film.
- Non-3M parts anywhere in the system. Another brand’s attachment, sealant or film substituted in — the most common failure in competitive bids.
- Splices, curved glass, non-flat surfaces. 3M does not warrant spliced film or film on three-dimensional glass. Epic’s precision-cut panels are one piece per lite.
- Removal or re-work by anyone but an authorized dealer. Including a well-meaning glazier or custodian.
- Acts of God, vandalism, misuse, acid rain. Structural movement, floods, fire and windstorms that damage the glazing are insurance events, not warranty events.
What the warranty does not pay for
Even on a valid claim, 3M covers the film, the glass up to the cap, and labor by a 3M-selected dealer. It does not cover moving or reinstalling window treatments, trim or mullions, lighting or furniture, or repainting. Replacement film carries the remaining term of the original warranty, not a new one. The warranty belongs to the original purchaser at the installed address and does not transfer to a new owner or tenant.
Straight talk on what film is
3M’s own bulletin says it plainly, and so do we: security window film is designed to hold broken glass in the frame and make it more difficult for an intruder to get through. It is not bulletproof and it does not prevent every injury or loss. The warranty covers the film’s performance as a product; the protection it provides is a matter of the glass, the frame, the attachment and the installation — which is what the Epic Method is about.
Call Epic first. 3M is the backstop.
Send a photo and the building address to [email protected], call 866.EPIC.117, or use the service request form. A real person replies within one business day, a Certified Installation Specialist handles the visit, and Epic files the claim with 3M and manages it to the end. If you ever cannot reach us, 3M’s window film group is at [email protected] or 1‑866‑499‑8857.
Two timing notes from 3M: film takes 30 days or more to fully cure, so haze and small water pockets in that period are normal, and 3M asks for 90 days before an adhesion or appearance claim. A lifted edge, a broken pane or a growing bubble does not need to wait — call.
Keep these three documents
- The 3M warranty certificate Epic delivers at closeout
- Your proof of purchase (the Epic invoice)
- Your glass or window manufacturer’s warranty, including seal-failure terms

Every window has a record — and initials on every step.
Each installer logs every window in Epic’s app and initials each step — cleaning, gasket out, wedges, film, solvent wipe, tape, the structural bead, cleanup. Every building we have worked on is cataloged by room and opening with its measurements and film code, so a repair starts with a photo and a room number, not a re-survey. With your permission, a one-inch Epic tag in the corner tells whoever runs the building next who to call. How the record works →
