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
If I have water damage from a leak, can I re-use DMX Airflow™?
Absolutely, just clean off the dirt and re-use. You will, however, require DMX Airflow™ Vapor Tape to re-seal the seams.
Can I lay laminate floor and engineering floors on it? Do I need to lay plywood or OSB in between?
You can lay laminate floors directly on top of DMX Airflow™, you do NOT require OSB or plywood in between
Why do I have to leave a ¼” gap around the perimeter of the room?
The ¼” gap allows the moisture a route to evaporate
Will the moisture not get into my stud walls?
No it will not, because stud wall are normally protected by tar paper or a vapor barrier of 6 mil poly
Can I lay DMX Airflow™ in every room of the house?
Yes, DMX Airflow™ has been designed to be laid in every room of the house, because mold and mildew can grow anywhere in the house

No, we do not recommend 6 mil Poly under or on top of DMX Airflow™.
Can I lay down WPC or SPC vinyl planks directly on top of DMX Airflow™? Do I need to put a layer of plywood or OSB in between?
Yes you can lay down WPC or SPC vinyl planks directly on top of DMX Airflow™, and plywood/OSB is NOT required in between as long as the load distribution of the furniture or cabinets do not exceed 8,250 lbs/sq.ft or 56 psi.
