In a previous article, we discussed the North American building code requirements for sheathing membranes and their function as water-resistive barriers (WRB). This third and last article of the blog series will uncover the additional, critical role of sheathing membranes as air barriers. Sheathing membranes that act as air barriers are typically of the polymeric […]
In Part 1 of this two-part blog series, we looked at what sheathing membranes are and how they are used in exterior wall assemblies. To recap, these membranes typically consist of thin sheet materials placed on the exterior side of the sheathing board in exterior wall assemblies. The function of the membranes is to resist […]

Today, people think about basements a little bit differently than in the past. While the idea of turning a basement into a livable and comfortable space seems like a necessity, it used to be the opposite.

Folks latch onto concepts that are partially true…true in a limited sense…without appreciation of the range of applicability. As Dirty Harry Callahan would say…a wall has got to know its limitations. There has been […]

I was using a good house wrap and taping the seams, and I was paying my insulation and drywall contractor extra to include “air-sealing measures.” I thought “No problem. I should […]
The best way to protect high-risk moisture environments – for walls and roofs It does not get any riskier than constructing an enclosure over an indoor swimming pool. Except maybe an enclosure over a pressurized and humidified hospital. Or, how about an enclosure over a conditioned museum designed by a famous architect who is […]
When it comes to protecting foundations, some builders only factor in code compliance. They simply spray a tar/asphalt coating on the concrete foundation and proceed with backfilling. Problem is, this approach is short-sighted, leading to spray-on foundation protection issues. Easily damaged spray-on coatings may create vulnerabilities on numerous levels, including moisture leading to mold and air quality problems, […]
