Kahrs Combo Underlayment

from Williamsburg, VA – Verified Buyer

I like the Kahrs underlayment. It is easy to install and it is well engineering to keep moisture off the bottom of the floating floor planks. I purchased two rolls and they were delivered on time and they were in good condition.

Kahrs Underlayment

from Lancaster, PA

Premium underlayment... this was used in a floating installation of a Kahrs engineered wood floor. Initially I wasn't sure this was the right decision, since it took a week or so for the wood to adhere to the slight contour of the concrete floor. This product has tiny white bubbles on the face-down side. The theory is that it provides a way for moisture to escape via the edges of the floor. Installation was VERY easy, and I would recommend for DIY. [...] has a very similar product for about the same price.

Kahrs Underlayment

from Hutchinson, MN – Verified Buyer

Easy to lay down and cut. Seam taping system is easy to use and secures well. Only downfall is that some areas of the foam beads came loose while cutting and make a mess.

Kahrs underlayment just acceptable

from Troy, VA – Verified Buyer

By the name you would expect the best but this underlayment is nothing special, and a little pricey. What it does buy you is a little insurance from excuses from Kahrs if you used their flooring
