As many of you have read I will be getting a new unit/furnace installed. In looking at my attic I noticed I did not have much insulation and in doing research I am currently at a R13 but should be at a R38.
My question to all of you if can help of course is, how many bags of cellulose insulation do I need for a 1500 sg ft attic to get to this level? Also I have been told that since this is not a new construction I can put however much insulation I want.(Of course not exceeding the R38) Is this a true statement?
I have no concept of R-value and no matter how much one explains to me and looking at the cellulose bag to see what they recommend I still get lost.(Was not very good at math ) I have asked for help and even they don't know.By the calculations that I come up with I am supposed to get 90 bags!!
I figured I want to save money on energy cost so this was another thing I was looking at. And I know many of you have seen plenty of insulation since you guys go up in the attic too. I just don't know who or where to ask. Thanks for all of your help.
