We're starting to see the spray-in foam insulation for new home construction in this market. You may see it also. However, down here where the humidity is high, improper insulation can create a major mold problem.


The stuff has to cure for at least 4 days but appears dry after 2 (but the inside is still moist and is emitting moisture through the foam). If the sheetrock is installed before it completely cures, the moisture will collect between the wall surface and the foam (no air movement) and create a perfect breeding ground for mold.

Just a heads up.

I've seen that insulation used in commercial metal buildings, but not residential. It burns really well, so all wiring is in conduit. And the insulation is sprayed with a fire retardant.
