Whoops! I bought 1.5" walls instead of 2"

[dotrosedotnet]

Will my foamie suffer from this? Should I try to replace it before I tackle the walls in the coming days?

Thanks so much for all the help!

1.5 worked for me........

If you find areas “thin” , you can always add extra foam ( scraps ) like foam gussets in corners and foam “ arches” on the roof …

1.5 works nicely because it is really close to 2 inch (nominal) dimensional lumber. I say "really close" because the actual thickness of the foam varies quite a bit with the OEM tolerance.

You have also gained 1" in length and width on the inside.
