    • 3/1 underlayment
      Verified Purchase

      I purchased this product as the underlayment for a laminate floor I installed. Very easy to work with and very comfortable on the feet. I went over a concrete slab. I would recommend using this product and will do so on my next flooring project in our home. Very reasonable price too.

    • Perfect underlayment
      Verified Purchase

      Just as advertised. The underlayment was perfect under my newly installed engineered hardwood floor. The acoustical element is great.

      Liked the pink underlay better but it wasn't available. Goes down easily but also tears easily.

    • Questionably wrong rolls sent
      Verified Purchase

      I believe OS might have sent the wrong product but due to timeline of our project we used and installed with what we received... I think they actually sent us a SP3 based on package label and color of material is not the red it is supposed to be but not the orange of the SP2 it's in the middle.. The product it's self is easy to work with and helps absorb the sound of a once carpets area. For the people who think the acoustic rating is to block the sound of neighbors that is not what it is designed for so please don't write negative reviews when you are not educated of the products intent. This rolls we received work great in the areas we used it, since I believe we received an SP3 instead of 4 I wish OS would have verified my order before they shipped.

    Questions & Answers

    • Q:

      "I bought some peel and stick thin laminate ( 2mm thick) off of here, would this be good for that? Im afraid that the thin laminate would feel spongy under a thicker underlayment."

      • A:

        Hello tallguy, thank you for your interest in this floor underlayment. This would work best under floating flooring. Have a great day!

    • Q:

      "what is the difference between sp-4 and sp-1?"

      • A:

        SP1 is just basic underlayment with standard noise reduction and moisture barrier. SP4 is high performance underlayment with sound Transmission Class (STC) 66 and Impact Insulation Class (IIC) 72.
