Re: Possible alternative to Reflectix?
if you have reflectix sandwiched between foam and hull it is touching two surfaces, the air gap isn't present there either really. If the bubble wrap counts as the air gap, then closed celled foam on boats sides counts just as much I would think, but since it's R-value is higher it would be a little better? I just can't see how one works and the other doesn't, something fishy about that. I can see the argument for the reflective only working if exposed to air, because the heat will conduct through the closed cell foam, but then that applies to both just as much?
Hull/reflective layer/bubblewrap/reflective layer/foam/
is not that different from hull/reflective layer/foam/reflective layer/foam?
