We recently decided to redo the floors in our basement with laminate. Our first choice was DMX Airflow. One look at the roll and the technology was evident, it looked like a better product from the get go, and it didn’t disappoint. The installation was fast and easy even for someone like me with little experience. I was quickly able to place and cut DMX Airflow with a simple pair of scissors. Once installed I could feel a noticeable difference in the warmth and comfort of our floors. This is a room we will enjoy for years and DMX Airflow is a big part of that. This is one of the best purchases I've made for our home.

I recently had a flood in my basement where I had to remove my flooring and underlayment, I decided to install DMX Airflow underlayment. The product is very light and it is really easy to work with. It stays flat when unrolled, you only have to seal it with the tape that is supplied with the product. It's impressive the difference of flooring temperature when installed, the underlayment stopped humidity and cold feeling of concrete, even before installing flooring. This is an amazing product, a lot better than what I had before, efficient to have a comfortable floor, in the basement.

"I had carpet with underpad directly over the concrete floor in my basement and could feel the damp environment and musty odour permeating over the years especially in the summer. I have now installed 300 Sq.ft. of DMX Airflow and 15mm laminate floor over it and it makes a huge improvement. My floor is warm and feels solid to walk on without even OSB installation. I am happy with the product and especially with good customer service of DMX, they responded to my questions and also especially stayed open on the weekend to pick up the product."

What is the compressive strength of DMX Airflow™?
The crush strength of DMX Airflow™ is 8,000 lbs/sq.ft or 55 psi, which means the dimples can support weight and maintain an air gap up to that load

Will the dimples in DMX Airflow™ compress over time?
As long as you don’t exceed the ultimate crush strength of the material – 8,000 pounds per square foot – the dimples will not get damaged. They will stay their current shape. DMX Airflow™ is warranted for 50 years

Will I have a problem if I want to put heavy furniture or a pool table on top of DMX Airflow™?
