InternationalAIR-SHIELD: Designing for the 21st Century
At W. R. MEADOWS of Canada, we understand that air barriers do more than just meet code—they protect your building’s performance, efficiency, and longevity. Whether you’re an architect designing with sustainability in mind, an engineer focused on airtight performance, a contractor navigating jobsite demands, or a distributor supporting your customers with trusted solutions, our complete line of air barrier systems is built to deliver.
Backed by decades of building science expertise and tested to perform in Canada’s toughest climates, our products offer reliable protection and peace of mind—so you can build with confidence, from the ground up.
Air Barrier Calculator
The W. R. MEADOWS Product Estimator app is a great way to learn all about our products. The app includes a coverage calculator that will spell out just how much product you will need once you input the project’s size. We feel this is a great app for all construction professionals, whether you’re an architect, contractor, engineer, or building owner.
