The Talk

By Rich Rinka

About 50 years ago, there were essentially only two window framing materials to choose from for residential buildings: wood and mill-finish aluminum, typically with single-pane glass. My childhood home near Milwaukee was like a lot of other homes that were built following World War II. Despite my father’s best attempts to add “storm windows” (read: putty glazed, ¼-inch glass in a wooden frame), ice formed on the interior surface of the glass during winter. It was accepted as the nature of things; heat loss was not a big consideration.

However, the first energy crisis of the 1970s and increasing utility costs focused attention on the energy efficiency aspects of windows. Consequently, within the last 30 years, we have seen the advent of low-emissivity coatings, low-conductance gas fills, “warm-edge” spacers and insulating frame systems based on a wide variety of polymerics, as well as wood and aluminum. 

The growth of the scope and depth of the underlying AAMA standards reflects this advancement. Originally just for aluminum, vinyl was added in 1986, and wood was included in 1997 with the original ancestor of today’s NAFS. The scope of the standards grew from covering 10 product types in 1968 to 45 today.

There are still a number of energy efficiency improvements available. Some of the emerging technologies are already nearing the practical stage, such as aerogel insulation and new configurations of triple or even quadruple glazing, such as “thin lightweight triple” glazing, capable of driving U-factors down to 0.10.

Recently, Lawrence Berkeley National Laboratory alumnus Stephen Selkowitz challenged AAMA national conference audience members to envision an even more wide-ranging future for fenestration. In terms of energy, the vision is for a “net zero envelope,” a concept that borrows from the California initiative to achieve Zero Net Energy—new residential buildings that produce as much as they use—by 2020. 

A significant challenge to be sure, but one that means new business opportunities, greater occupant benefits and increased real estate value.  Read More
