Building my first board out of XPS pink foam. 2 questions so far:

  1. The more I read I keep seeing XPS delaminates easier than EPS. Is this build a mistake or is there something I can do to help prevent the fiberglass from delam?

  2. Since this is a closed cell foam, are vent plugs still necessary to install?

Thanks for the advice. Any other helpful tips are welcomed

Is this a bump?
Happy to respond if somebody actually needs current input.

Start here. If there is genuine interest, I will add more…
