KPS System A is our most widely used pressure equalized Rainscreen system. It possesses all of the performance features of our KPS System A-Plus, but with enhanced cost efficiency provided by the modified perimeter frame.  For projects without curved panels, KPS System A is the way to go.  The perimeter frame is invisible, providing a sleek panel edge condition.  And, of course, it achieves instantaneous pressure equalization as tested by the AAMA 508-07 Rainscreen evaluation.
