GBlist: Re: EEBA-L: environmental expanding foam sealant
We use Handi-Foam (Fomo Products, P.O. Box 1078 Norton, OH 44203) which
is a one part, polyurethane, hcfc,low-expanding foam. We buy it direct
from the mfr by the pallet load, but it is available retail through
Shelter Supply in Minneapolis, phone (800)762-8399. I've shot hundreds
of cans of the stuff into SIP joints, around windows, and general crack
filling on the job.
Handi-foam is much more user friendly than some of the hardware store
varieties. It expands 2-3 times the original size of the bead (rather
than 10-20 times), dries tack free within 20 minutes, and is totally
cured in 24 hours. Cured foam is R-5 per inch.
It sticks to everything, including skin. Once its on your hands, you
have to wear it off. Wear gloves and old clothes. It's a good idea to
finish a can once it's started, since it can be difficult to adequately
clean the nozzle to keep it from glogging before a second use. Handi-foam
does offer a gun, which is cleanable, but I have no experience with it.
The one-part foam comes in 12 & 24 oz cans and 10 lb tanks. A case (12)
of the 24 oz cans costs $142.92 from Shelter. The two part foam comes in
25 and 55 lb tanks.
