At Marvin, we believe that delivering peace of mind to our customers should last beyond the initial purchase of our quality products. That’s why Marvin windows and doors are covered by our industry-leading Limited Warranty. We stand behind every product with a goal to inspire better ways of living for our customers.

How to Identify a Marvin Window or Door

For Products Manufactured after November 2003

Marvin products manufactured after November 2003 feature a laser etched logo and product identifiers. The etching is found on the interior of the glass, in the corner of the window sash, or door panel. This etching contains the following:

Glass manufacturer-Plant YearCIG-G 03
IG glass certification abbreviationsIGCC@CBA IGMAC
Serial NumberC03604162118
NFRC NumberNFRC-007/010/246/247
Manufacturing CompanyMarvin Windows and Doors
For Products Manufactured before November 2003

For window products manufactured before November 2003, examine the silver-colored spacer bar between the panes of insulating glass. The spacer bar runs along the outside perimeter of the glass. If the product was manufactured by Marvin, the spacer bar will bear an engraving that displays the Marvin name, and the last two digits identify the year of manufacture. The engraving may appear at any point around the perimeter of the glass.
