Figure 3 illustrates one way of sealing the cavity behind the siding at the corner of the building. Although the rainscreen wall may sound like a new concept, it has been used for years in brick veneer construction, where the air space behind the face brick is vented or drained at the bottom. A vented and drained cladding is not a true rainscreen wall until it is compartmentalized and the inner layer of the wall is made air tight. It is easy to adapt this concept to conventional construction to create a true rainscreen wall. Figures 3 and 4 show a few of the details that may be considered for rainscreen design at the corners of a wood frame house: siding to siding compartment and siding to brick veneer compartment.
