Reply to comment by Eirikur_da_Czech in diy blown in insulation question for first timer. 100+ year old home. by jjax2003

thats what i wantd to do. i thought cellulose was blown in. maybe i am confused. its a small space, i would have a very hard time fitting up there to do any manual work. so i wanted to blow everything in as it would make it way easier

Cellulose is blown in. It is more efficient than fiberglass too.

You still want to get up in there to seal any air gaps. It's a lot of work, but if you don't do this, all the insulation in the world will only get you so far.

Blown in is a good option, but sealing is very important.
