The normal screen frame height (B) is 74". If the people using the Screen Room, Patio Room are tall, one may wish to consider purchasing the optional (B) 83" high screen frames. In order to have proper water run-off from the roof a minimum slope is required. This slope is determined by a combination of the height of the screen frames and the projection of the Screen Room, Patio Room. Projection is the distance one would walk away from the house or trailer to which the Screen Room, Patio Room is attached.
