*Insulation* - 3M Thinsulate - worth it?

[Mr. Electric Wizard]

Thanks Greg, I saw this in your thread. Your bus is coming along nicely!
For installation simplicity I think I'm going to go with some of the flexible elastomeric closed cell foam stuff.

You could check out the "spaceloft" gel insulation by Aspen aerogels - comes in 57" wide rolls. No idea on cost. R value of R=1 per 0.1" thick, so the 0.4" thick product would be around R=4, which is about as good as it gets. FYI It is not a gel and is moisture and mold proof.

Nothing in the literature says it's applicable to automobiles, but it does say it remains effective up to 390 degrees. These products were developed for NASA (just like the bubblefoil insulation)

FWIW, it looks like the thinner (0.24" thick, R=2.4) spaceloft is about $4/SF on ebay (about $0.50 more per SF over 3M thinsulate).

EDIT: I emailed their company and they sell the 0.4" (R-4) product direct for $5/SF+shipping, no minimum order. They also said that this material would work well in automobile/RV applications.

Thanks for posting the Aerogel info! Been looking for that off and on for a long time since seeing a video on tiny houses that were shown on the Washington DC mall grounds. One structure had Aerogel between panes of glass to make a insulated wall that allowed plenty of light thru.

With a layer of bubble wrap (reflects heat back outward) on the outward side of the Aerogel should do the trick in our Buses.

I'm not sure any other product would be needed if you went with the aerogel - it looks like it insulates against high temps pretty well

That Space Loft stuff looks pretty cool but they don't say if it retains moisture or not.
