Everlastic® EVA-200 Applications

Compartmentalization of the cavity wall system will equalize the negative pressure within the wall cavity to the exterior positive pressure more quickly and efficiently when using PVC brick vents, cell vents or open head joints.

This is of significant importance when considering that a driving rain is sucked through the brick veneer into the cavity by the negative pressure within the cavity.

The quicker the pressure is equalized the less the water in the cavity.

It is very important to compartmentalize at the corners to avoid air flowing around the corner carrying moisture down the adjacent cavity.
