Installation Instructions for Replacement of Aluminum Windows in Hard Coat Stucco
Applications in arid climates.
These instructions are designed for typical California hard coat stucco exterior applications. The
installation must leave the existing aluminum window frame and weep system in place. These
instructions are not to be used with any other construction method and rely on the integrity
of the existing aluminum window frame and flashing system. Building designs, construction
methods, building materials, and site conditions unique to your project may require an installation
method different from these instructions and additional care. Determining the appropriate
installation method is the responsibility of you, your architect, or construction professional. If you
have questions, please contact your local Pella retailer.
