West Union, IOWA FLOLO Farm 52175 | I'm guessing it'd take a short course in physics to explain it all, but you have 4 different propeties at work........wood,tin,metal fastener and foam..
Freeze,thaw & condesation can do some strange things and compound things "here" maybe you're dry enough and warmer it'd never show.
but I do know my foam guy will not spray under a cold roof, and he's sprayed enough foam to retire in the winters in AZ. |
