I’ll soon be looking into insulating the sidewalls of my 60s vintage frame ranch. I’ve been planning to use blown in cellulose or fiberglass, the old standard. I wonder, though, if someone has developed a system to use foam in finished stud bays. It sure would be nice to avoid the dust and possibly use smaller holes. New advances, applications and materials seem to pop up monthly these days. Any info would be appreciated.

Hi Bill,
Do you have any knowledge or experience with this stuff?
The web site is somewhat sketchy but I didn't dig too deep into the tech pages yet.
I get the feeling that the foam is created outside the wall and then it's pumped in.
I'll definitely look into this more. Thanx for the reference.
