Hardwood Floors February/March 2026

MOISTURE AND VAPOR RETARDERS NWFA Guidelines along with most flooring manufacturers provide guidance on vapor retarder requirements, including whether one is required and the recommended class rating. Underlayments vary in their permeance (per ASTM E96), and vapor retarders generally serve one purpose: protecting against moisture vapor emission. When your acoustical underlayment does not publish a moisture permeability, consider using both a vapor retarder and an acoustical underlayment. This combination satisfies manufacturer requirements while delivering a quieter, more enjoyable installation. It’s a simple step that pays off in long-term durability. EASE OF USE Finally, a good acoustical underlayment should be easy to handle and install. It should not be prone to damage simply from working on top of it. The old saying applies: “You get what you pay for.” Investing in a high-quality acoustical underlayment ensures long-term performance, comfort, and peace of mind. Acoustical underlayments should not be seen as an afterthought, but as a critical component of a successful flooring project. U E w
