windhund42 posted:I never asked where to buy Homosote to begin with and I certainly know how to use a website "Find a retailer" function. All responses to my questions have been very helpful and I thank all of you. I think "Homacote" is made by the same company that makes Homasote, thus the name similarity.
I'm leaning toward a foam layer over my 3/4 inch plywood base instead of Homasote.
From what I searched, there is NO such product called Homacote. What you may have seen was someone else’s typo, when actually referring to “Homasote”, which happens to be made locally, within 5 miles of me, in Trenton, NJ. Other references to Homobed/Homabed, as being a product made by Homasote, are also wrong.
