Q. At what value should my vents be set to release?

A. The vents should be set as low as practical, yet remain in place during wind storm conditions. In general 20 lb/ft2 is accepted as that practical value. The NFPA suggests a maximum of 30 lb/ft2 in areas subject to severe wind conditions whereas FM recommends a maximum of 40 lb/ft2.

There’s an Explovent for every condition.
