Dream Home Insulayment Premium Underlayment for Glue and Nail Down Hardwood Floors 100 sqft. Roll, $59.99 USD/Box, LL Flooring (Lumber Liquidators)

Designed for glued-down or nailed hardwood and engineered wood floors, Dream Home's Insulayment offers sound insulation and floor cushioning. It maintains warmth in winter and coolness in summer, with an antimicrobial structure added as a benefit. It complies with most condo associations’ soundproofing standards. Suitable for glue-down or nail-down solid and engineered wood flooring; also approved for use over radiant heated flooring. Some compressibility is necessary for its effectiveness, yet some deflection might cause minimal floor noise, particularly in nail-down applications, but this is not considered a defect.
