Hi,
Anybody on htis board familiar with InjectASeal?   Marketing material states that it is a "nitrogen based aminoplast".  The rep told me that it is "corn based" and, therefore, "very eco friendly".  Material states that it has R=4.6, density is 1.0-1.8 lb/ft^3, and perm=10.

After reading all of the info on this board trying to figure out how this foam material fits in with others and whether there is anybody with experience with this product?

From it's K-value, installed density, and high perm rating it sounds similar to other non-expanding injection foams used in commercial masonry walls or studwall retrofits such as TriPolymer or CoreFill500 etc, (and quite different from spray polyurethanes or spray polyisocyanurate foams or similar, such as CorBond, Demilec, Icynene, etc. which are all expanding foams, and much less permeable at 1-2lb densities.)
