R-Value determination is pretty much a national standard. I would suggest you contact the manufacturer directly if you wish to ask them of their R-Value determination methodology. http://www.robertsconsolidated.com/wp-content/uploads/2016/05/70-025_PDS_M2914-8999.pdf

I had to do a new "Woven Bamboo" wood floor on concrete. This underlay is a must, unless it is a straight glue down. Under-lay vs Glue down: I find with the underlayment that the floor has a better feel and the "acclimation" process is just better. Straight glue down is cold and hard and really does suck, in my opinion! I believe most warranties require underlayment and for good reason I may add...

Used this under some pergo presto. It was a bit unruly since the way it is rolled, you have to roll it from underneath, but all in all a great buy and provides good enough cushion. Unfortunately this was the wrong product for our uses, the type of flooring we used requires an underlayment without moisture barrier if you have a crawl space. Luckily i'd only done a 10x10 room before realizing that mistake and returning the extra rolls was very easy. Some of the underlayment that we'd already cut and couldn't return was used to put under a metal dog crate to keep it from scratching the floor, also the dog is a sloppy drinker so it keeps water spills from ruining the wood laminate.

For the price point, this was a fantastic buy and a great product. I would buy it again. Went in easily and loved the taping for the seams. It was nice and cushy. Now that the floor is in, it's a joy to walk on and very warm even in winter.

I just installed this underlayment in my front bedroom and had no problems. This is a very good product and a great value. It went down with no problems. The seams sealed perfectly to form a nice seal over the entire floor. I would highly recommend this product and plan to use it again in the near future. I see absolutely no reason to spend a huge amount of money for an underlayment and this product proves my point.

Underlayment at the right price and quality
I used this underlayment in conjunction with black 6 mil moisture barrier, for laminate flooring. Roberts under-layment does provide 2 mil moisture barrier which should be adequate for most non concrete sub floor app- lications. My kids enjoyed laying the underlayment. The finished floor feels and sounds nice. I would suggest buying some regular duct tape as well. It is rather easy while installing your laminate to inadvertently scratch and puncture your underlayment.
