These mats are thinner than expected and have not held up under light wear.
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.
Just wanted to say - do not expect much after installing this product - this is the average item, just regular undergarment under laminating floor. Don't think it can be declared as having acoustical barrier - my neighbors still hear me perfectly and I can hear them with no changes.
