Hi everyone, 

I hope you're doing well.

I am currently working on creating a laminated glass configuration:
9/16" Laminated Glass – 1/4" HS Low Iron + 0.09 PVB + 1/4" HS Low Iron. see attachment 

However, I could not find this specific configuration in Windows. As a result, I created it in Optics, but I encountered an issue—Optics flipped the layers. It seems that Optics does not allow the Low-E coating to be in direct contact with the interlayers.


Would you happen to know a solution for this? Any guidance on how to properly configure this glass in Optics while maintaining the correct layer order would be greatly appreciated.

Please let me know your thoughts. Thank you in advance for your help!

Best regards,

Danellis H

This is a limitation of Optics. With a few exceptions, low-E's cannot be placed against the interlayer. Are you sure you need these embedded low-E's? 

There are some prebuilt laminates in the IGDB with 1 low-E surface against the interlayer but I don't know of any with 2 against the interlayer. Manufacturers test laminate stacks with embedded low-E's for this exact reason. They can't be built in optics so they test them for submission directly to the IGDB.
