Blown cellulose full of shredded plastic
Building what I think will be a better than a good enough house. Frankly got a lot of help reading here and Allison Bailes. Thank you.
House in Zone 3 southern Utah. Gets very hot here but with beautiful landscapes.
Using a lot of wet cellulose spray in the 10″ double stud walls. First pass went well, stuck to OSB, etc. Couple of days later, second pass not so well from a sticking point of view. What became very obvious was that there was an awful lot of shredded plastic, mostly from what appears to be shopping bags.
My theory is that all those imbedded slippery plastic “sheets” interfere with the expected bonding of the paper based cellulose fibers. How can many of them stick together when there a slippery “wall” between them? Way too many sprayed bays topple, mostly slide down.
Contractor denies the second batch is different. Baloney. I am ALWAYS present when any build activity is taking place. I saw how well the first layer laid and no plastic.
QUESTION: is it good practice spraying so much shredded plastic on walls?
