Dense pack cellulose vs fiberglass batts
Fretted
| Posted in Energy Efficiency and Durability on
I have been unable to find a dense pack installer in my area and find that none of the appropriate insulation machine are available for rental anywhere near me. I have read where Habitat for Humanity in Denver has used three layers of fiberglass batts with good success. I believe cellulose is a better product but would appreciate any and all suggestions.
Thanks,

How thick is your wall? If the batts don’t evenly add up to your wall thickness you’re going to have a challenging time of things.
Personally I’d consider mineral wool too. It’s a little more expensive than fiberglass but easier to work with, and fireproof. I switched a while ago and will never go back! In your case, if you have to built it up in layers, the fact that mineral wool has a bit of rigidity to it (it holds its shape) will probably be very helpful since it won’t be constantly trying to fall down on you while you install it.

I would not use fiberglass if it was free. Lots of experience tells me its garbage. Better then nothing but not as much as you might think.
Mineral wool/roxul as mentioned is a good alternate but i would not give up looking for dense packed cellulose. And don't accept loose fill cellulose. Better then fiberglass but dense pack is where the money is.
