1.1 This standard practice covers the installation of windows in new construction utilizing a membrane/drainage system of no more than 3 stories in height. It is expected that all referenced components shall meet code requirements in force at the time of installation.
1.2 Representative installation methods described in this document have been water tested up to a design pressure of 575 Pascals (12 pst) water test pressure, using the ASTM E 331 water test, to simulate extreme exposure conditions. This pressure was selected based on the
AAMA/WDMA/CSA 101/I.S. 2/A440 criteria.
1.3 This practice applies to windows which employ a
mounting flange or fm that is attached and sealed to the window perimeter frame and is designed as an installation fastening appendage.
1.4 This standard practice covers the installation process for windows from pre- to post-installation. It does not include fabrication techniques that would be required to join individual windows to each other, either horizontally or vertically. It also does not cover any other factory or
field fabrication which joins or combines multiple
windows. The instructions for mulling windows together and any accessories required shall be supplied by the window manufacturer.
1.5 This standard practice provides minimum
requirements for window installation based on current best practices. Actual conditions in buildings may vary. In cases where variations occur, the installer shall consult with the window manufacturer or registered design professional. If this standard practice conflicts with the
manufacturer's instructions, the manufacturer's
instructions shall take precedence.
1.6 This standard practice does not address safety
concerns, either from the installation process or those that may be present at the building site. It shall be the responsibility of the user of this standard practice to ensure that all appropriate health and safety practices have been implemented.
