Review: Good value easy to use - Good value worked for my purpose under carpeting Review: I highly recommend PolyFoam—it’s affordable and effective. - After our kitchen flooded and the Eucalyptus solid wood flooring warped, we replaced it ourselves. We removed the damaged flooring, dried the subfloor with fans, and used PolyFoam Multipurpose Foam Underlayment, which was significantly less expensive than contractor-recommended brands. We ordered new Eucalyptus flooring and stacked the wet boards to dry. When the new flooring arrived and acclimated, we alternated the best original planks with the new ones, creating an attractive, contrasting pattern that looked better than the professionals’ work. I highly recommend PolyFoam—it’s affordable and effective. We even used leftover underlayment and flooring to finish our master bedroom. ## Features - Multipurpose Foam Underlayment – Ideal for laminate and engineered wood flooring; bridges minor subfloor imperfections for a smoother surface. - Moisture-Resistant Barrier – Helps block moisture from concrete or wood subfloors to protect flooring from long-term damage. - ROLL SIZE - 100 sq. ft.

The packaging is not ideal, it comes wrapped in thin plastic that is only taped securely at the top. Mine ripped during shipment and left a couple tears in the first layer on the roll. The tape for the product label also ripped the foam when I tried to peel it off. This is easy to work around and only some was damaged. Overall its a very thin foam and will work well for my intended purpose, and it's a good value for the amount (at least compared to other foam sheet products). I wish the plastic it came packaged in was a thicker plastic, or taped in more areas. ## Frequently Bought Together - PolyFoam PF080400100 Basic Foam Underlayment for Wood & Laminate Flooring, 100 sq ft, White - ROBERTS 50-040 Underlayment Tape Roll, Red - ROBERTS 70-115 Moisture Barricade Underlayment Film, for Vinyl, Laminate SPC, Engineered Wood Floors, 6 mil.
