Air-Sealing Beneath Hardwood Floors
We will be installing hardwood flooring with nails and I’m hoping to find an underlayment that will help maintain a good (if not perfect) air seal between the topside of the floor and the crawlspace underneath. Are there any good products or techniques for this? Unfortunately, floating is currently off the table.
