First post here... I was just at Home Depot and picked up a bag of enviro-cellulose insulation that looks to be recycled paper and wood products. Its fluffy, and the the thought occurred to me that this could be used for ground foam if it was dyed. Im going to give it a go with some Rit, but I was wondering if anyone has every used this product for ground foam. Ive search around to new end. It seems like a fairly decent idea, but I dont know if this stuff is going to get mucky with water or whatever.
