I am looking into insulating my garage and maybe sound deadening some interior basement walls with dense pack cell. One side has sheathing in the garage, and I have drywall on one side of the basement walls. The polypropylene webbing/netting is quite expensive (Haynes insulweb 8'x750' is $410.00 a roll)
Is there any alternate materials that could be used? In the garage I'm not sure if I need a vapor barrier as the walls are 2x6 construction, but if I need to use a VB then I would need to hang poly after I blow. i won't need a VB on the interior basement walls.
I have seen online some dense pack done using 6mil reinforced poly for both the netting and VB.
Other thoughts were to try to use Tyvek or siimilar house wrap with a rip stop or reinforcement weave to it.
