What is the compressive strength of DMX Airflow™?
The compressive strength of DMX Airflow™ is 8,250 lbs/sq.ft or 56 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 compressive strength of the material – 8,250 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™?
Heavy furniture, including pool tables, can be placed over DMX Airflow as long as weight distribution is less than 8,250 lbs/sq.ft or 56 psi.
Is it waterproof on both sides?
Yes DMX Airflow™ is completely waterproof on both the top and bottom sides of the membrane
