Adhesion and Compatibility: The Unsung Essentials Among Installation Sealants, November
Sealants represent a very small part of the cost of an overall wall system, but play a major role in the integrity of a residential or light commercial building’s roof-to-ground weather resistant barrier (WRB). They do so under significant pressures, by providing protection that must remain intact despite being stretched or compressed due to thermal movement, wind load pressures, operation of windows or doors, settling of structures and other forces.

Ensuring Long-Term Performance: IGU Specifications and Test Methods Slated for Updates, October
The single most important element that’s vital to the overall, long-term thermal performance of a complete fenestration system is the performance and durability of its sealed insulating glass (SIG). Fogging can interfere with that performance (and visibility) when the organic components to which insulating glass units (IGUs) are exposed (such as sealants, exterior components, adhesives, muntin bars, spacers and others) become volatile and condense, forming a “fog” on the inner glass surfaces. Loss of gas filling and compromise of the seals are also concerns.

In Search of the “Best” Windows; Standards Ensure that Whatever You Choose, It’ll Perform, August/September
AAMA sometimes receives inquiries as to what are the “best” windows to use. I was told by a former co-worker before I joined AAMA that the “best” window is the one that your spouse likes. In reality, the answer is a bit more involved.

Hurricane-Tested Standards; Impact Products Must Be Installed Properly to Work, June/July
As the 2018 hurricane season ramps up, it is timely to review how special care in door and window installation can help withstand such storms.

There are three key considerations: structural resistance to high wind pressures, ability to withstand impact from windborne debris and resistance to penetration of wind-driven torrential rains. Installation quality is of particular importance in the case of water penetration, which has been cited as a major cause of failure for exposed door and window installations.

Safety: A Clash of Cultures; Make Sure Your Jobsite Values the Well-Being of Workers, May
You have probably seen it at a construction site—particularly on a residential job. Workers are young, tend to be brash, and fancy themselves tough guys immune to accident or injury. Employees sometimes roll their eyes at Personal Protective Equipment (PPE), scoffing at Occupational Safety and Health Administration (OSHA) regulations. Some giggle at the idea of fall protection. They think it won’t happen to them.

Fiberglass Reaches the Next Level; Updates to Standard Reflect Material’s Growing Stature, March
Window performance is a complicated concept. The big picture is not defined just by U-value or glass type. It is not discerned by debating the purported merits of the different framing material. Each framing material offers its own unique performance characteristics and special advantages for dealing with the performance challenges posed by climate, building design, buyer preference and/or budget for various applications. Any controversy based on the purported generic superiority of material type is rendered virtually immaterial when one stops comparing the basic characteristics of isolated samples of unsupported material and concentrates on the performance of the complete fenestration unit.

NAFS 2017 Updates; It’s More User-Friendly Than the Previous Version, February
A fitting cap to an eventful year was the release of the 2017 edition of the North American
Fenestration Standard (NAFS) — aka AAMA/WDMA/CSA 101/IS2/A440. Six years in the making since the previous 2011 edition, the updated standard for windows, doors and skylights features revisions that at once expand coverage yet render the standard significantly more user-friendly.

PVC Use Grows As Technology Advances; Strong Standards Have Helped Spark a Materials Revolution, December/January
A landmark in the industry’s historic progression beyond fenestration framing made of either wood or aluminum was AAMA 303, Voluntary Specification for Rigid Polyvinyl Chloride (PVC) Exterior Profiles. Issued 20 years ago, it was the first among today’s polymeric material specifications, which now include six formulations in addition to PVC (fiberglass, ABS, composites, etc.).
