Amino Foam is a highly flowable foam that can fill CMU cavities from below—rising as much as 18 vertical feet. Click to enlarge.

Some of what we’re found has been surprising. Anyone remember urea formaldehyde foam insulation (UFFI)? Back in the late 1970s and early 1980s it was the ultimate bad guy of the insulation world. Installed in hundreds of thousands of homes in the U.S. and Canada following the 1973 Energy Crisis, UFFI was found to emit high levels of formaldehyde in some circumstances and shrink considerably, resulting in performance problems. The Canadian government spent millions of dollars insulating 80,000 to 100,000 homes with this insulation, then spent many more millions uninstalling it when reports of problems emerged. Canada banned the product, as did the Consumer Products Safety Commission in 1982 in the U.S.—though the latter later reversed the ban a year later. read more
