Your source for the latest on high performance air and moisture barriers. From changing building codes to new building techniques, our experts are here to provide you with the information you need to build to a higher standard.
If you haven’t experienced the gross inconvenience and expense of a leaky basement, count yourself lucky. If you have, you know it is not something that can just be ignored in hopes it will go unnoticed or perhaps “fix itself.” Basement leaks can either be slow and steady, gradually seeping into a dwelling over days, […]
Stucco and manufactured stone have been used in the building industry for ages. These claddings are well known, and well used for their leading properties in fire resistance, durability, and aesthetics. In fact, according to the Census Bureau’s recent Survey of Construction, 25% of homes built in the US in 2017 used stucco cladding; second […]
Air barriers are no longer just a passing consideration. They are not only federally mandated, but also demanded by code-conscious and sustainability-oriented building owners and occupants who are in the know. For good reason, too. A high-performing air barrier means greater comfort at a lesser cost. Based on simulations, the National Institute of Standards and […]
“Code is a four-letter word for the worst building you can build without going to jail.” Building science engineer Dr. John Straube called it like it is at the latest DELTA® Academy Seminar Series in Washington, DC. His message was loud and clear: merely meeting code does not and should not cut it in an […]
Today, many builders are increasingly leaning towards green construction. According to Canadian study World Green Building Trends 2018, 35% of Canadian firms who participated in the study report that more than 60% of their projects are green, and by 2021 the number of firms to achieve this is expected to rise to 48%. What’s interesting is […]
Today, net-zero energy initiatives are taking the building industry by storm. These are homes designed and built to generate as much energy as they consume, once all renewable energy systems are fully installed—with the goal of reducing the energy needed to maintain them. According to a standard set by the NZEC, net-zero energy structures are […]
When maintaining long-term building integrity, airtightness is an important feature to keep in mind. Airtightness simply means that there are no unintended gaps in the building envelope—gaps that would otherwise cause air leakage in or out of the building. It is an essential performance parameter in helping ensure energy efficiency. How airtightness is achieved comes […]
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 […]
When it comes to maintaining a building’s integrity and longevity, protecting the building from factors that contribute to moisture-related issues is key. How do moisture-related issues materialize to begin with? According to research, wind-driven rain on a building’s façade is considered one of the largest sources of moisture2 and, most commonly, moisture is the number […]
