Installation Frequently Asked Questions

Does FGIA publish anything related to the proper installation of windows?

Yes, the following documents are available for purchase from the FGIA Online Store.

  • FMA/AAMA 100-12, Standard Practice for the Installation of Windows with Flanges or Mounting Fins in Wood Frame Construction for Extreme Wind/Water Conditions
  • FMA/AAMA 200-12, Standard Practice for the Installation of Windows with Frontal Flanges for Surface Barrier Masonry Construction for Extreme Wind/Water Conditions
  • AAMA 2400-10, Standard Practice for Installation of Windows with an Exterior Flush Fin Over an Existing Window Frame
  • AAMA 2410-13, Standard Practice for Installation of Windows with an Exterior Flush Fin Over an Existing Window Frame
  • AAMA IPCB-08, Standard Practice for the Installation of Windows and Doors in Commercial Buildings

Though AAMA publishes these standard practices, it is important to understand that in all cases, “Windows shall be installed and flashed in accordance with the manufacturer’s written installation instructions.” This very same language is contained in the International Residential Code (IRC) for One and Two-Family Dwellings.


How do I renew my InstallationMasters™ certification?

AAMA licensed the InstallationMasters™ program (training, testing and certification of window installers) several years ago to Architectural Testing, Inc. of York, PA. They can be reached at 717-764-7700.

Does FGIA have installation instructions for mounting-flanged windows?

Yes. InstallationMasters was developed to train and certify installers on industry accepted installation practices. The program includes an installer-training manual that is available for purchase by anyone who has an interest in proper window installation. 

Though FGIA publishes standard best practices, it is important to understand that in all cases windows should be installed and flashed in accordance with the manufacturer’s written installation instructions. This language is contained in the International Residential Code (IRC) for One and Two-Family Dwellings.

If my window, door or skylight has an AAMA label on it does that mean that the window and installation is approved by AAMA?

No, the AAMA (Gold, Silver or White) Label indicates that the manufacturer is authorized by AAMA to display the label. By placing an AAMA certification label on a product, the manufacturer certifies that the labeled product meets the applicable performance requirements of the standard cited on the label. The label applies to the construction and performance of the window as it leaves the factory, not to its performance once installed.

Can FGIA assist me in resolving my window installation problem?

FGIA staff can only provide interpretations on questions that relate to the content of our documents and certification program procedures.

Can FGIA assist me in finding a qualified residential and light commercial window and/or exterior glass door installer?

Yes, a list of certified installers who have successfully completed the InstallationMasters program can be found at installationmasters.com.
