richard sucher II Posted: Jun 10, 2010 08:53 AM	Heatlok yields Typical yield numbers for the biobased closed cell foam systems that we have sprayed @ 80 degrees have been 42-4500 bd. ft./set. Looking at Soy based Heatlok and am curious what experience applicators have had with this material yield wise. Under fairly ideal conditions, what yields have they experienced. At less than ideal conditions such as cold weather, what have those yields dropped to. Lets say less than 50 degrees on concrete or metal. Realize that there can be a large range here but am curious to see if the answers that are provided correspond with other biobased systems or are unique to soy based systems. Any and all input would be appreciated.

Heatlok has a MINIMAL amount of SOY, According to their D-6866 its about 10% of the "B" side, so its a little much to call this soy foam. In reality, it shoots about the same as any other non-soy foam. Some guys claim as much as 4500 bdft, others lament they cant get 3000. The truth is that the applicator makes the biggest difference. That being said, there have been instances the past few months of manufacturers sending out older, sometimes re-labeled material. Older usually means slower. Slower means less yield. I am NOT saying that is what happened to you, but it is definately a possibility. The market being what it is, sometimes manufacturers get caught with too much inventory. I dont think a material is "SOY" unless it has significant soy content, say 25% of more on the "B" side. True soy materials have a tighter cell structure, and usually yield a little higher than non-soy materials. Again, it is the applicator that makes the biggest difference. High soy content gives a larger application window in heats and pressures. This also adds to the applicators margin for error. There is a soy manufacturer getting ready to release a 30%+ bio content material. I understand it is a pretty good and easy material to shoot. I am sure they will splash it here. Try that one before you judge soy materials.
