I have some insulation I put up a couple of months ago and never covered with drywall. I went up and looked at it today and it was discolored in some areas just like the ones in these pics:
(Those are pics of some other guys insulatin on another thread but mine look exactly like that.)
Someone on that thread said it is normal and just discoloration.
I can't remember if it was like that when I put it up or not and I am wondering if it's normal or not.
Someone told the guy on the other thread who's pics are above to spay bleach on them to find out if it is indeed mold or just discoloration, does anyone know what the bleach would do if sprayed on to let you know if it is mold or not?
Air seal around the electrical boxes- switches, outlets, etc.- as you lose -100 times more there than through diffusion. If you have access to the rim joists, foam board them and air seal with canned foam: http://www.buildingscience.com/docum...-at-rim-joist/ Solid rim wood is R-1.25 per inch.......
