The following articles written by Rich Rinka (AAMA Technical Manager, Standards and Industry Affairs) were originally published in Door and Window Manufacturer Magazine.
Drainage Systems: Hidden Helpers; They Keep Water Out, But You Don’t Always See Them, June/July
"The vertical elements of the building envelope—including doors and windows—should be viewed as a complete system rather than a collection of separate components. The portion of this system known as the water-resistive barrier (WRB) must shed rainwater from the roof to the ground without allowing penetration into the wall cavity or the building interior. The critical consideration in a door or window installation is to
be certain that it is fully integrated with the WRB, thereby maintaining the integrity of the drainage plane of the exterior wall."
Stop Leaks, Improve Performance: Integrating Doors and Windows with Water-Resistive Barriers, May
"Product certification, while verifying robust resistance to water penetration, cannot ensure the intended
performance of doors and windows after installation. Even the best-designed product can allow excessive water penetration if installed improperly."
Who Tests the Testers? Accreditation is Critical When Choosing a Laboratory, March
"Quality professionals know that repeatability and reproducibility (R&R) of measuring devices are cornerstones of reliable quality control. In the product-certification world, the R&R concept translates to
ensuring that test results are consistent, agreeing from test to test (repeatability) and from lab to lab (reproducibility). Only in this way can a reliable comparison be made among products in terms of whether they meet the requirements of the North American Fenestration Standard (NAFS). This is particularly important for manufacturers of residential fenestration products, who depend heavily on certification to NAFS to differentiate their products."
Drip, Drip, Drip... Standards Help Avoid Condensation Aggravation, February
"While condensation on windows was once considered to be little more than an unavoidable nuisance, nowadays it is taken much more seriously. The collection of moisture can stain or damage interior surfaces and degrade the indoor environment. In primarily residential venues, this can result in mold growth and lead to costly remediation and even lawsuits over alleged toxic reactions."
Make Sure Your Coatings are Covered: Paints, Finishes Must Meet Rigorous Certification, Too, December/January (by Dean Lewis)
"In this series of articles that concludes with this installment, we have examined the importance of
components in ensuring long-term fenestration product performance—especially as employed in the AAMA
Component Verification Program, a subset of the AAMA Certification Program. In addition to hardware,
sealants and weatherstripping discussed in previous articles, the finish applied to the basic framing material is critical as well."
