We will be removing all the drywall on the west side of our central FL
home shortly, it all needs replacing due to termite and hurricane
damage. I recently saw a home improvement show that demonstrated a
spray on insulation. It was made of soy, and it expanded after being
sprayed on the inside of the outer wall. It was then cut flush with the
studs before the drywall was put in place. Our west side gets full sun,
and the rooms get measurably warmer. This is one of the long sides of
our rectangular shaped home. We've just replaced doors and windows, but
even in early June you can feel the difference from the east to west
side of the home. We currently have fiberglass batting, but it's been
damaged by water in most of the west walls. Any opinions on whether
this be a product worth looking into, and if so, who would you contact
to do this sort of work or can it be done DIY? Any ideas on how it
compares costwise to fiberglass batting replacement?
