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 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.
Moisture intrusion in a wall system can cause numerous building defects as well as health ailments for building occupants. This course will review the cause and effects of moisture intrusion and will discuss how fiber cement panels can be used as a rainscreen to mitigate this moisture. We will identify different rainscreen technologies and ASTM and AAMA testing standards that measure their performance. By the end of the course you will understand basic design approaches and guidelines for installing fiber cement panels as a rainscreen.
This article demonstrates that foam plastic insulation (polyiso board and spray polyurethane foam) can be used in code-approvable wall assemblies that work in cold, warm, marine and humid climates. Architects will be able to create alternatives to vapor permeable wall assemblies that address three main concerns: NFPA 285 flame spread tests, mitigating moisture retention within walls, and delivering higher insulating performance with greater levels of comfort.
