How to Identify a Marvin Window or Door
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 information:

MARVIN WINDOWS AND DOORS |
When contacting a Marvin retailer regarding a service request or warranty claim, please provide them with the product’s serial number. It is used to validate that the product was manufactured by Marvin and to retrieve original order information that can be helpful when servicing your window or door.
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.
Example: MARVIN IGICC@CBA 1-96

A Marvin swinging or sliding door can be identified by its beige Ultrex sill. Ultrex is not metal or vinyl. It is a pultruded fiberglass material with superior strength and durability. |
