Sound/thermal insulation

[mayble]

Anyone have experience with this material?  Similar to Reflectix, but with closed cell foam instead of the bubble wrap layer.

I've read about this product being used as pictured but not on van walls and ceiling.

comments were good regarding making the vehicle quieter and reducing heat transfer. Might be a good choice.

in high traffic areas the foam breaks down. I have no idea about using it on walls and ceilings. they give no R value? highdesertranger

Trying to find an R-value comparison (since the company didn't see fit to include it), REI's closed-cell foam mats (one w/aluminum surface) have R values of 2.6 to 2.8 for 0.6" thickness. Polyiso's R-value for 1/2" is 3 (1" = 6).

Car Insulation = $1.41 per sq ft.
Polyiso at Home Depot = $0.43 per sq ft (both about 1/2" thickness).

I sent an email to the Car Insulation company, and the contact person said it had an R value of 1, with dead air space probably a bit more.
