AAMA Releases a Number of New Fenestration-Related Documents 

The American Architectural Manufacturers Association (AAMA) has released a number of new fenestration-related documents.
Included in the new documents is AAMA 800-05, a technical specification that covers performance and test methods for sealants. The revamped 25-page document titled Voluntary Specifications and Test Methods for Sealants, was first published in 1992.

Guideline specifications to assist architects, engineers, manufacturers and code officials in reducing the hazardous consequences of a blast force on fenestration systems, have also been published. AAMA 510-06, Voluntary Guide Specification for Blast Hazard Mitigation for Fenestration Systems, directs manufacturers to the appropriate resources to simulate blast conditions in a laboratory environment in order to evaluate and compare fenestration system performance in a standardized manner. 

A key document for assisting architects and specifiers in the development of hurricane resistance specifications for fenestration products has also been revised. Originally published in 2000, the updated document is AAMA 506-06, Voluntary Specifications for Hurricane Impact and Cycle Testing of Fenestration Products.

The Voluntary Performance Rating Method for Mulled Fenestration Assemblies has also been updated and published as AAMA 450-06. First developed in 2000, the standard details a voluntary testing and rating method to determine air infiltration, water penetration resistance and structural performance of factory-built or knocked-down field mulled fenestration assemblies.

IGMAs Thermal Stress Working Group to Survey Manufacturers

The Insulating Glass Manufacturers Alliance (IGMA) has formed the Thermal Stress Working Group to gather information and provide guidelines relating to thermal stress considerations for window glass products used in residential and commercial building envelope projects. The association says the purpose will be to develop specific guidelines and design assistance for avoiding breakage caused by thermal stress conditions.

These guidelines will follow a format similar to the IGMA technical publication TM-4100-03, Preventing Insulating Glass Failures. The project will consider conditions known to be important to thermal stress in glass, a knowledge base of reference materials, available industry information, dos and donts guidelines for thermal stress and practical design considerations for the review and analysis of thermal stress.

As an initial step, the task group is issuing a one-page survey report on thermal stress breakages in the field.

Florida Building Commission Meets, Hears Results of Study

The Florida Building Commission (FBC) met last month to receive the results of two studies regarding hurricane protection in the Gulf Coast. The University of Florida Field Study of Hurricane Season 2004 and the Panhandle study performed by Applied Research Associates (ARA) were both presented to the FBC.

ARA reported that its findings show a correlation between the amount of wind-borne debris damage and tree density in the surrounding area, rather than wind speed, a finding determined by a cost-benefit analysis. 

The FBCs work groups on windows and water intrusion had met May, 31 in Tampa, Fla., as well. One of the topics the work group tackled was label requirements, such as a standardized format for all third-party certification labels, sufficient size for labels and how installation information can be a part of a supplemental label. 

The product approval and validation work group met on June 1 and looked at options for improving the validation process. The group addressed the four methods of product approval, a continuation of its last meeting. 

The group also discussed an update of the Florida Panhandle Wind Borne Debris Study, consideration and decisions about how to act on products and product approval and the proposed 2006 glitch cycle amendments to the 2004 Florida Building Code as offered by the technical advisory committee.
