EV-A.40+ Pressure Equalized Rainscreen System (PERS)

Designed using the rainscreen principle utilizing pressure equalization, the EV-A.40 Pressure Equalized Rainscreen System (PER) (formerly the RRPER System) incorporates concealed venting, allowing for rapid pressure equalization while preventing water infiltration. Tested to the AAMA 508 standards, the EV-A.40 PER System provides a solid engineered option to the rainscreen question. Using the idea that less layout is better, the EV-A.40 System attaches directly to the substructure through the continuous perimeter framing members. Additionally, the perimeter framing allows for simplistic compartmentalization.
