Insulation options behind hullliner

[markpierce]

Too bad many boats don't already come insulated.

Mark:

Aaron's boat came the same way yours did: unfinished. He's just getting to the insulation part a little later in the boat's life than you are.

The hassle with blue board is IT BURNS ! , so it must be covered .

The Coast Guard document below explains why using blue board may be a bad idea.* Be sure you understand how easly it burns before you use it.* Sorry for the small attachment, but if you open it, then hit "control +" a few times it should be readable..............Arctic Traveller

Artic, I think the Coast Guard warning applies to polyurethane foams sprayed on hulls, but a greater fire hazard caution applies to polystyrene, which is what blue board is made of.* The CC is particularly concerned about polyurethanes because when they burn, most all of them give off cyanide gas and dense smoke.* As most people executed in gas chambers will tell you, this can really ruin your day.*

It wouldn't be my first choice putting blue board on a boat because of the flame hazard and smoke, which is your point and worth considering since much safer alternatives exist.
