AAMA Publishes New Installation Standard for Doors in Wood Frame ConstructionJuly 24, 2012
The American Architectural Manufacturers Association (AAMA) has published FMA/AAMA/WDMA 300-12, Standard Practice for the Installation of Exterior Doors in Wood Frame Construction for Extreme Wind/Water Exposure. The document, developed in conjunction with the Fenestration Manufacturers Association (FMA) and the Window and Door Manufacturers Association (WDMA), includes procedures for the installation of exterior doors into residential and light commercial buildings of not more than three stories above grade in height.
"This standard is an important addition to the lineup of installation practices developed by the industry to provide guidance to door installers in the extreme conditions frequently seen in coastal conditions such as in Florida,” says Steve Strawn (JELD-WEN), member of the AAMA/FMA/WDMA Installation Method Coordination Committee. “Many code officials have recognized the value of the existing standard practices, and we expect adoption of the 300-12 into the next code editions."
Developed by the AAMA/FMA/WDMA Installation Method Coordination Committee, the standard is designed for installations that are subject to extreme wind and water climate exposure and addresses buildings that will be at high risk for water intrusion.
Specifically, FMA/AAMA/WDMA 300-12 addresses three scenarios for integrating side-hinged or sliding doors with a membrane drainage plane: doors with mounting flanges, doors with exterior casing/brick molding and non-flanged box frame units.
Comparable to the 300 document, AAMA has also published FMA/AAMA 100-12, Standard Practice for the Installation of Windows with Flanges or Mounting Fins in Wood Frame Construction. FMA/AAMA 100-12, updated from the 2007 version, includes procedures for the installation of windows into wood frame buildings of not more than three stories above grade in height. This standard is also designed for installations that are subject to extreme wind and water climate exposure.
Both FMA/AAMA/WDMA 300-12 and FMA/AAMA 100-12 are available for purchase from AAMA’s Publication Store.
