[QUOTE="onthewater102, post: 377923, member: 13702"] There are also two types of polystyrene foam sold for home insulation - extruded and expanded. Only extruded is closed cell, so it shouldn't absorb water over time. Of course it's the one you want to use and naturally the more expensive of the two. I opted to go with the expanding 2-part marine urethane foam - just meant i had to design cavities which could be filled separately and i needed drainage lines from the front compartment to the rear of the boat for any rainwater/splash etc. that gets up front to have someplace to go...I'm very happy with it as it let me use FRP sheeting for the decking material & kept the whole boat very light while being a fraction the cost of aluminum sheeting...
