Are there any tips or tricks for removing foil backing from Polyisocyanurate insulation foam board? I'm ready to insert it into the train table and figured it would come off both sides in one sheet. Wrong. It's coming off in slivers. It's going to take me a long time to remove it like this unless someone can offer so insight or suggestions.
It was stored in my very cold garage for a couple weeks. Do I need to let it warm up to room temperature first?
