InsulStar Insulation

[Elisabeth]

Is anyone familiar with Insulstar. It is a spray-in-place product. R-value is said to be 21 at 3". I understand walls can be 2x4; not 2x6. My home plan does specify 2x6. The cavity does not have to be completely filled. Pricing is about $3.00 a square foot.

I'd get it for the FEMA class 4 rating alone.

I'd probably have to design around it though, especially in a wood structure.
