FAQ | DMX Airflow

1. 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.

2. 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.

3. 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 8,000 lbs/sq.ft or 55 psi.

4. Is it waterproof on both sides

Yes DMX Airflow™ is completely waterproof on both the top and bottom sides of the membrane.

5. If I have water damage from a leak, can I re-use DMX Airflow™?

The ¼” gap allows the moisture a route to evaporate.
