Identify if you have an Andersen® Window
Andersen windows are identified by the Andersen logo on the glass. All sash will have the logo. The logo will be in one of the corners of the glass. It is etched on the glass and cannot be washed off. It is very light and you almost have to be looking for it to see it. The logo is a triangle with the letters "AW" in the center of the triangle. This logo means that your window is an Andersen. If you don't have the logo on the glass, you don't have an Andersen window.

Note: there will be other letters and numbers on the outside of the triangle. These other letters and numbers contain information about who manufactured the glass and the date of manufacture. |
Figure 1 - 1970 to 1975
In 1975 Cardinal began to identify the month of manufacture in the logo (figure 2). For example, C175 indicated Cardinal glass manufactured in January 1975. The numerical month/year designation continued until July 1984 when Cardinal returned to a quarter/year designation. In January 1975 Cardinal began to use plant designations of "M" or "G" after the glass date. In 1981 they added an additional plant designation of "S". In 1979 Cardinal added the IGCC code under the AW logo.
In 1984 Cardinal stopped using the letter codes to designate plant manufacturing locations, and switched to a number code after the C or CIG (for Cardinal IG).
In the 2nd quarter of 1987, the glass date changed back to year and quarter (figure 6), and the date and IGCC code were relocated over the logo. The number after CIG indicates manufacturing plant location.
