envelope components. Transitions and detailing between major components create 90 percent
of leakage problems, although they represent only 1 percent of an envelope area (90%/1%
principle presented in Chap. 1). Besides permitting leaking water into interior areas, this
leakage creates damage to structural components.
Manufacturers provide recommended installation details for their products and systems,
and these should be followed without exception. If a particular installation presents spe-
cific detailing problems, a manufacturer’s representative will review the proposed transi-
tions and actual installations as necessary. This inspection requirement is one of the major
advantages of the joint manufacturer and contractor warranties discussed in Chap. 11.
In addition to manufactured system components for transitions, several frequently used
transition systems and materials are used in building construction. These systems provide
watertight transitions between various primary envelope components when installed prop-
erly. Standard available systems include:
