Anyone have any experience with this stuff? I'm trying to replace the old scuttle panel for access to my attic with a contraption that I am trying to make out of some 2" (thickest I could find) foam board and Masonite. Reason for doing this is that my bedroom closet gets very cold in the winter, I ASSume because the ceiling is well insulated but the panel is just very thin plywood. 2 questions:
1) It appears that in an effort to make a tight fit, I cut the foam board just a little big. Is there an easy way to shave it down a little? It doesn't "shave" well with a knife. Am thinking Surform file? Or will that just make a mess?2) What do you use to glue it? I'm trying to laminate three pieces together for better insulation (the bottom most piece will be hanging; I cut it slightly smaller so it'll fit in the "jamb" area of the scuttle hole. That one will be faced with Masonite for a finished appearance.) construction adhesive isn't doing it (I put 8-10 dots on there.) Should I just use more construction adhesive, or is there something better?
thanks
