A strong air barrier is fundamental to the ecosystem of high-performing, durable, and passive buildings of tomorrow. As one looks to the future, building transformation would not be complete without an air barrier system (ABS) and its control layers contributing to a winning formula that is designed, designated, and detailed to control water, vapour, and air.
In an exclusive interview, Maxime Duzyk, director of building science and engineering, North America, with Huntsman Building Solutions, spoke to Construction Canada about a new insulation application method that can save building owners both time and money.
Rainscreens as external cladding have been around for decades, but advancements in technology have made them increasingly popular. This is due to two key factors—their ability to deliver optimal performance metrics, and the flexibility they provide when it comes to design options.
While improving energy efficiency is the key goal, the other benefits of air barriers, such as helping control the interior environment, providing a durable design, and creating a high-performing building, should all be closely considered in air barrier material selection.
The terms “air barrier” and “vapour retarder” (or “vapour barrier”) are perhaps some of the most poorly understood concepts in the construction industry. A general lack of understanding of the functions of these materials has resulted in simplistic rules-of- thumb. It is crucial the industry agrees on terminology that communicates the specific functions and purpose of these materials to avoid confusion and costly errors.
The Centre for Construction and Engineering Technologies at George Brown College, Toronto, in co-operation with a manufacturer is studying the performance of continuous air barrier, vapour retarder, and fibreglass insulation products.
On Thursday, February 15, CSC’s Vancouver Island Chapter will hold a luncheon meeting on “Air Barrier Design and Airtightness Testing.” Held at Fireside Grill from 11:30 a.m. to 1:45 p.m., the seminar will provide a brief overview of the B.C. Energy Step Code.
Use of two-pound, medium-density closed-cell sprayed polyurethane foam (SPF) is growing rapidly in commercial structures. Utilization of the material has been fuelled in large part by its ability to seal the structure and, in doing so, tremendously enhance energy efficiency.
