SOLAR HEATING SYSTEM CONSTRUCTION LOG
PROGRESS REPORT: July 24 Insulating the barn - day 2
The
insulation foam installation took less time
for
the first floor - about 3 hours since it was more accessible
and
no ceiling to do. Yesterday they had delays due to
the
spray nozzle clogging up, but today went smoothly.
I
was impressed when they told me that the spraying
equipment
was worth over $100,000!
After
installation some of the excess had to be chipped away.
It
is as easy to cut as stale bread, and can be cut with a
bread
knife, or chipped out with the claw of a hammer.
-
the texture reminds me of hokey sci-fi sets like all the
cave
sets in the original Star Trek series!
