| Abstract | The rainscreen concept was first referenced as a means of rain penetration control in the 1940's. Later researchers applied physics principles to develop the 'pressure equalized rainscreen principle' as it is known today. Through the development process a selection of terminology has been used to describe the concept which uses a rainscreen to control rain penetration due to the kinetic energy of raindrops. 'Cavity wall', 'open rainscreen wall', 'rainscreen principle' and. 'two stage weather tightness' are key words commonly encountered in literature addressing the control of rain penetration. In most cases, the concepts also addressed the control of rain penetration by other forces such as gravity, surface tension and capillarity. Some specifically addressed the control of rain penetration by wind induced air pressure difference across the wall system. The fundamental differences between these wall concepts are never clearly described. Consequently, when the rainscreen concept is applied to wall design, these key words are used interchangeably and it is difficult to know what is really meant when a wall is required to be designed according to, for example, the 'rainscreen principle'. |
