Hi, I live on a fiberglass power boat & we are not allowed to use our BBQs on the dock. Has anyone got ideas on insulation products to insulate my 18" WSM so that I don't melt my fiberglass? I was thinking of using Kaowool blanket to shield the fiberglass from heat, or maybe just surrounding the WSM with it? I have a small sheet of 1/2" Homasote board (used for model railroad layouts). Isn't this product originally used for lining fireplaces, would this work under the WSM? Any suggestions will be welcome.
