Water Management in Shower Installations

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.

Designing for Energy Performance (Print Course)

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.

A Rainscreen Solution Using Fiber Cement Architectural Wall Panels (on-line version)

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.

Robust Walls with Continuous Foam Plastic Insulation (Print Course)

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.

As buildings use less and less energy to heat and cool by owner demand, HVAC systems offer increasingly less assistance in drying out walls. The HVAC systems are no longer designed to take on additional loads caused by moisture in walls that needs to be removed. However, energy bills may increase beyond expectations to address wall moisture issues with no discernable benefit to the occupants if moisture in walls is not addressed.

Moisture Durability Opportunities in Green Standards / Codes

Many green standards lack sufficient measures to ensure long-term durability of wall assemblies. Unfortunately, some energy efficient designs, while code compliant may adversely impact durability. The importance of increase moisture management capabilities, such as effective drainage, will be demonstrated using tools and simulations to assist in designing energy-efficient and durable walls.

Moisture Mitigation with Rainscreen Technologies (Print Course)

There is no such thing as a water-tight structure. Because water takes the path of least resistance, it will find even the smallest opening in the building envelope, allowing moisture to enter the wall system, no matter how many layers of protection are provided. Therefore, in addition to keeping water out with various weather resistive barriers (WRB), systems must be put in place to allow water to exit the envelope once it inevitably does get in.
