The simple explanation that describes the function of an exterior wall assembly is that it separates the exterior environment from the interior environment. To perform this “simple function” the assembly must control heat flow, control air flow, control water vapor flow, control rain penetration, control light, solar and other radiation, control noise, control fire, [...]
Over the past 5+ years, 1,000+ Net-Zero (NZ) and Net-Zero-Ready (NZR) homes have been built in Canada under the Canadian Home Builders’ Association’s Net Zero Home Program. And with that sample size, and with energy codes are trending toward the Net Zero Ready benchmark, it’s time to ask ourselves – what have we learned? [...]
Logix Brands offer two engineered insulation products that help mitigate Radon ingress into homes and buildings: Halo Subterra Plus and Heat-Sheet Heavy. However, the functions of these two products are vastly different. Subterra Plus is a superior radon barrier alternative to 6-mil poly, whereas Heat-Sheet Heavy is a more effective gas permeable layer than [...]
In a previous Logix Brands blog post “Transition Details at Grade” were reviewed and one finding was that failures often don’t occur in the field of a wall, roof or the foundation, but rather at the transition from one control layer or material to another control layer or material (i.e. air control layer from [...]
Buildings need a lot of things to be successful. As Joseph Lstiburek, Ph.D. from Building Science Corporation would say, “What we call things tell us a great deal about how much we understand things. If we don’t call things by their right names, we don’t really understand how things work. If we don’t understand [...]
Adding exterior continuous insulation such as, Halo® Exterra®, to an above grade wall assembly helps to keep the air behind the foam board insulation at a higher temperature. The benefit of air at a higher temperature means it can hold more moisture. This attribute is clearly illustrated when reviewing various air temperatures and the [...]
R24 detail using Logix ICF, Halo Subterra and Halo Exterra Last month our Think with Logix® blog post looked at four transition details at grade for a cold climate. The below and above grade wall assemblies we used as an example essentially resulted in an effective R24 thermal resistance. This got us [...]
Importance of Detailing Transitions Failures of the building enclosure can occur within a wall, roof, or the foundation, however, more often than not a failure occurs at the transition from one assembly or material to another (i.e. above grade wall to foundation wall or exterior to interior air barrier system). A failure at a [...]
In our previous post, we’ve discussed the challenges of traditional window design; namely, that windows fail at some point and it’s important to design a window system that manages water between the window to wall interface. Now, in our follow-up article, we’ll shed light on some simple techniques that can help you water-proof window [...]
Windows and the window-wall interface are significant contributors to water problems in residential buildings. But to eliminate the issue, the architectural community must move past the debate of whether a window will leak; as it almost always will. Instead, the focus should be on strategies to manage water leakage between the window and wall [...]
