At a home improvement trade show, I saw a demonstration of ICYNENE insulation. You can get current details at www.icynene.com. If I ever build a house, it is what I would put in the walls and ceilings.

It is a sprayed on product from Canada that uses the heat from hot water as the energy to cause expansion. It does not "gas off" after about a week or so, and is EPA approved. It won't support combustion, and I saw the company rep put a blow torch to it.

The expansion is on the order of 100:1, so a minute amount sprayed in causes a considerable amount of foam to be produced. That means it will weigh very little if one could use it to surround the cockpit. By its very nature, it would surround cables and prevent them from chafing against the structure. If one needed to get at what it is covering, a pocket knife would do the trick. In a typical home installation, a flimsy hand saw is used to trim the excess hanging past studs with a few quick strokes.

To those interested in doing the research, this may be a product worth investigating. I haven't spent the time because I don't need it yet.
