I have two quotes on putting down a hardwood floor in my home. One
installer says that heavy duty poly sheet is best, another showed his
underlayment and it looks like roofing paper to me. The floor would be
installed over 3/4 plywood over a crawlspace. We will be using a 3/4
prefinished hardwood floor. What are the opinions out there regarding
underlayment?
Thanks
