Water penetration is tested on cladding attachment fasteners. Read about the scope of the testing, the results, and best practices to reduce risk under severe conditions.
This course will identify the importance of detailing continuity in maintaining the integrity of the four control layers of the building enclosure. We will then explore some different methods for identifying the areas where continuity can be disrupted and the solutions for maintaining a control layer continuity in these areas.
This course will explore different types of rainscreens. We will look at systems that are non-structural, structural, and proprietary. This course will cover an overview of these rainscreen examples and technical details for specific construction types such as wood framed, steel framed, and masonry walls. It will review the rationale behind good rainscreen design and some of the design requirements stipulated by codes, standards and best practice references.
Of all the different insulation options available today in commercial construction, spray foam can provide outstanding thermal performance while also contributing to air sealing, moisture control, and even structural integrity. This learning unit will provide an overview of spray foam insulation, how it differs from conventional insulation types, its most appropriate applications, and how the material is allowed to be used in fire-resistant construction.
Wall assembly components such as CI and WRBs are now required across the country, requiring in-depth understanding of wall systems. Improper design of transition details can lead to detrimental and expensive issues in wall assemblies. This course reviews building science fundamentals for complete wall systems with CI and WRBs, important considerations when designing transitions and penetrations, and common issues that arise from errors in sequencing, material compatibility and design verification.
This course provides guidance for architects, specifiers, waterproofing contractors, and other professionals considering use and advantages in the selection or specification of air and water barriers for the design and installation of integrated structural panel and air and water barrier systems. Topics covered include: introduction to air and water barriers, structural panels, code and regulatory requirements when designing for energy code compliance, and common design and installation practices and techniques.
This course is designed to increase your knowledge of moisture management and continuous insulation technologies in wall assemblies as applied to multi-family building construction. The course will cover drainable wrap technologies, continuous insulation options, proper flashing options, industry standards, and a case study related to multi-family wall assembly performance.
Tiled shower demand is growing by double digits. Showers are getting bigger, more luxurious, and more expensive. Five million new tiled showers are installed every year! Most shower problems are not detected until after at least a year and any warranties have expired. In this course, specifiers and wet-area construction tradespeople will be able to effectively explain the benefits of using bonded waterproofing membranes in a fully bonded shower system for a better, longer-lasting product.
In the design of building enclosures an emerging alternative is the use of spray foam insulation as exterior continuous insulation featuring the ability to resist heat, water, vapor and air movement in an uninterrupted, continuous performance installation. A significant outcome is the control of moisture mechanisms in buildings.
How spray foam insulationâ€™s water resistive, air barrier and insulation characteristics help to control moisture is examined in detail. That it is a proven option that offers such performance in addition to allowing for design freedom and flexible installation is also discussed.
For the past decade plus, energy codes continuously increased their requirements for energy efficiency of buildings. Codes began by increasing insulation requirements and recently added an air barrier requirement to reduce air leakage of conditioned air.
The codes include prescriptive and performance requirements; however, the prescriptive requirements are what most designers utilize. Following the prescriptive requirements without consideration of the environmental conditions, both exterior and interior, can result in unintended performance of wall and roof systems. This article will discuss the current state of the code requirements, both prescriptive and performance, as well as when prescriptive requirements may result in inadequate performance.
