Existing blown in attic insulation and adding more???
I just finished sealing up all the entry holes in the top of the walls where pipes and wires run through as well as sealing all the can fixtures and the 2x4s that form the top of the wall where the sheet rock is attacted and the ceiling joists sit on ( dont recall the proper name) sorry
anyhoo..... I have about six inches of grey blown in material, there are shields over the soffet holes and i could easilly spray in another six inches
can i do this? An what material should i use? I will try an do it myself
