Low permeance vapor barriers, once thought to improve performance, may in fact increase interior condensation and trap moisture within the wall assembly. Due to the problems with impermeable water-resistive barrier (WRB) installation many architects are now incorporating highly vapor open WRB systems in their designs. But many still believe too much permeability is bad for a wall assembly. Studies show that highly permeable WRB systems increase substrate drying, reduce the wet time of absorptive claddings allowing permeable WRB membranes to enhance the wall assembly performance. This presentation investigates the current research on vapor open systems and discusses how more permeability enhances wall assembly performance....

Understanding the performance of building materials in real-world conditions is key to a successful building design. Recent studies have shown that the commonly reported R-values of polyisocyanurate foams at room temperature may overstate their real-world performance in cooler temperatures, potentially resulting in gaps in designed building enclosure assembly performance and quality. Through a theoretical framework and empirical data, this course shows that optimized polyisocyanurate foam insulation results in better performance, leading to improved energy savings and reduced potential for condensation. Participants are encouraged to explore innovative insulation materials, understand differences between them, and match optimal materials to specific applications while meeting modern construction codes and regulations. By matching the right insulation materials to the application, architects can contribute to energy-efficient and cost-conscious construction practices and help buildings reduce their impact on the environment....
