10'8" x 34" x 4"
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
