Question 2 blow or not 2 blow & how much is 2 much.

I had to replace part of the ceiling in the kit. and a lot of the old 50's insulation fell out. Well I think that the best way is to DIY blow- in stuff. I can see the top of the 2x4's where the old stuff is , so in the place where I had to replace, there is 0 & the other is well up to the 2x4's. I have looked at the many ???? in "here"& I hope this all makes sence 2 someone.And how much is to much. I know that I can;t put more than the drywall will hold.
So not 100% sure what to do. I have to buy 10 bags to get the blower. The house is a 1 &1/2 story bungalow, attic on both sides
bedroom in the middle.
sorry this is soooooo long.
any help will taken in. Thanks

You can add insulation to the recommended values, if economically feasible. For instance, R49 is recommended in the attic here. That would 15.75 inches. The 2x4 in your house is likely 3.5 inches wide so your insulation is 3.5 inches deep. That would be about R15.

The ceiling sheetrock is usually 5/8 inch thick and will hold the insulation. To figure how much you need, multiply attic length by width by the needed depth.

Hope this helps.
