Wow, thanks for this Larry. I see I've got quite a bit to do when I go up in my attic this spring. Take me a shovel up there and move some cellulose around so I can get to everything.
I get mildew and possibly mold around the windowsill in my house. I'm going to have to take off all the frame and spray foam the window too. Not to mention caulk it from the outside. I better start making a list of what i want to do and in what order. Once I change the lights to ceiling fans I'll go up there and start working on the cieling. I may have more questions for you as time goes on.
Thanks again.
