and FMA Release Window Installation Standard
FMA/AAMA 100-07, a standard addressing window installation, has
been released jointly by the American Architectural Manufacturers
Association (AAMA) and the Fenestration Manufacturers Association
(FMA). According to AAMA technical director John Lewis, the 13-page
document titled Standard Practice for the Installation of Windows
with Flanges or Mounting Fins in Wood Frame Construction specifically
addresses new construction of no more than three stories in height
utilizing a membrane/drainage system.
The document also provides minimum requirements for window installation
based on current best practices and applies to windows employing
a mounting flange or fin that is attached and sealed to the window
perimeter frame and is designed as an installation fastening appendage.
The techniques demonstrated in this document have been developed
specifically to allow incidental water entering from superficial
cracks, either in the cladding, window joinery or installation joints
around the perimeter of the window, to drain onto the membrane drainage
plane and to exit to the building exterior.
"This standard is specifically designed for installations subject
to hurricane-force wind and water exposure, particularly in the
coastal Southeast United States, and addresses buildings that will
be at high risk for water intrusion. Thus, preventative measures
have been included that are above normal installation practices,"
The Standard Practice for the Installation of Windows with Flanges
or Mounting Fins in Wood Frame Construction is available through
download, CD or paper copy at a cost of $30.00 for non-members and
$15.00 for members.
