Re: Should I use Polyurethane foam when I replace floor?
It's different solutions.<br /><br />If you want it to bond with the hull, floor and other parts to build a selfsupporting structure that is strong, you should use something like the recommended foam. You pour it in and it expands into all corners and openings. Can be cut after expanding. Impossible (or almost) to remove later on so you must cover areas that is not supposed to be treated.<br /><br />If you want to fill rather square room you could cut blocks of styro. Easy to remove if needed.<br /><br />Before actually doing the expanding job you might wanna get a sample and experiment with filling various objects.
