Re: M_Boats: m-15 floatation
"two part closed cell foam " If you are talking about 2 part pour foam...the type where you mix part "a" with part "b" and it instantly starts growing and forming foam....be careful. If you mix this stuff in a closed container where it cannot expand as it needs to...or if it forms solid foam and blocks off its own exit while it is still expanding .....it can do some scary things! Just know that it IS going to expand....even if it needs to push you hull liner or cockpit walls out of the way to do it...IT IS going to expand! Make sure to carefully calculate how much you mix so you don't turn your Monty 15 into a Monty 19! Please do not ask that I relate how I became familiar with the expansion properties of 2 part pour foam!! :-) let's just say that I have had "confirmation" of some part of the above statement!

Sean is right. Even if there is a substantial opening for the foam to expand out of, it can do scary things. (I, too, speak from personal experience) Tod Mills M17 #408, 1987 galley model BuscaBrisas

I'm sure the foam type affects insulating ability far less than the method of installation. If I wanted to insulate a hull, I think I'd install vertical furring strips on xx centers, cut a foam sleeping pad (flexible) to fit against the hull between the strips, and then install ceiling strips over the mess. A couple on the TSBB did that when restoring their boat and it really looks great and I'm sure noticeably helps insulate both thermally and acoustically. Not sure that I'd try that on a 17, though.

That's the basic theory, except it would be an icebox built into the side of a hull, so the insulating foam would be poured in place past, under and around the interior box, suspended in space with drain already in place. I was thinking 3 or 4 inches of insulation, but that may be overkill. Howard On Oct 22, 2009, at 10:09 AM, <htmills@zoominternet.net> wrote:

3 or 4 inches? If you have the room, I'd definitely go for it. Tod
