Rambling on a cold winter night

I was truly imazed at how rapidly the smoke filled the spaces and how hot the steel bulkheads got.

Has anyone tried this stuff

there is an insulation called "armaflex" that is fire resistant - installation on boats is covered in the "plastic classic" forum.

we go out a lot in winter in british columbia.
I make limited use of "astro-foil" - an air filled polyethylene bubble between two reflective foil layers. It is light, thin, easily cut, can be used indoors or out, water resistant, cheap, easy to work with and has both reflective and conductive insulating properties.
I dont use it anywhere that fire might be an issue.
I found it at a local hardware store where they were selling it mostly as additional insulation for hot hater heaters.
see it at, eg:
ASTRO-FOIL - Reflects Heat - Stops Air Infiltration - Acts as Vapor Barrier

Anyone know the ABYC rules on this?

Like I said, they do make a fire resistant foam. I just do not think I would go to the expense. For wire rins, you could spend a few extra bucks and run the wiring through UV elec grade PVC conduit (the gray stuff). It is also available at home depot. But just being honest, I would not.

Thanks for all the input, I'm liking CD's recommendation, especially the $$ factor
JRP, I wonder if the spray on stuff the Navy has experimented with is similar to what they sprayed on my trucks bed? Rhino or Line X type?

While T37Chef will probably be okay with some sort of off-the-shelf insulation board, I'm going to disagree a bit about whether the fire/fume hazard from certain insulations is a big deal or not.
Over the years, I've read several accounts describing smoldering insulation fires that forced abandonment of the boat because the toxicity of the fumes was overwhelming, making it impossible to combat what would otherwise have been a manageable fire.
We tend to read about these incidents in connection with insulated metal boats, but some insulated fiberglass boats are also vulnerable. Builders of metal boats always face a dilemma as they decide on how/whether to insulate their hulls (besides the thermal and acoustic qualities, proper insulation can minimize the corrosive effects of condensation on the interior of steel hulls.) Most opt for insulation, since the benefits generally outweighing the risks, but as BillyR mentioned they live with the nagging worry about fire (especially insidious electrical fires from wire runs through the insulation).
The U.S. Navy recently (within the past few years) developed and tested a new foam insulation that is supposed to be non-flammable/non-toxic. I think it was spray-on, but I'm not positive of that. I don't know whether it has trickled into the market yet.
