Mitigating Moisture in Multifamily Housing Projects
Learning Objectives:
- Discuss the importance of developing a comprehensive water management system within a range of multifamily building projects in terms of envelope integrity and the health, safety, and well-being of residents.
- Describe the utilization of an established water management system that ensures materials have been tested and proven to work effectively together to maximize water damage prevention—key to elevating the living conditions of multifamily home residents.
- List best practices for the proper installation of a successful water management system in the featured multifamily housing projects, as well as provide an overview of the products selected to ensure structural durability as well as occupant health/safety.
- Discuss how codes and safety standards influence the specification of systems that facilitate proper water management in the featured multifamily housing case studies.

As the multifamily housing sector continues to grow, technical advancements allow for more efficient and tighter enclosures. Even still, moisture problems continue to be a cause of concern. The infiltration of moisture can often lead to structural deterioration, a diminished lifespan of exterior claddings, paints and finishes, as well as being a major contributor to mold growth, unhealthy buildings, and poor indoor air quality.
With that in mind, the quick removal of liquid bulk water and water vapor is critical in order to avoid damage to structural components. The use of comprehensive water management systems can mitigate these issues. Beyond merely applying building paper or a wrap, these advanced systems involve employing proven water management principles to develop a moisture management system that addresses all the mechanisms of moisture movement, informing everything from architectural design and product selection to construction practice. Preventing moisture damage and call backs is inherently about implementing a system that effectively controls moisture in both liquid and vapor form. This webinar’s expert presenters will provide an overview and multifamily housing case studies that feature a range of water management systems, products, and accessories.
This presentation will discuss essential water management system considerations and how they relate to modern, efficient designs. We will cover the critical wall system components, details and building code considerations for best moisture management in common wall assemblies while addressing material and performance considerations. We will discuss the mechanisms of moisture transfer vs. cladding selection and how a robust moisture management plan contributes to resilience and healthier building environments. This presentation will close by highlighting common issues in the field, how to address these with simple solutions and how to avoid critical mistakes.

TAMLYN is a family-owned company with 50 years in the building products industry and has placed a great deal of recent focus on building science, especially moisture management. This direction led to the development of their TamlynWrap® line, Drainable with its 1.5mm bonded filament creating an enhanced WRB, and RainScreen 6.3 (1/4”) and 10.1 (3/8”). TamlynWrap® RainScreen is a multi-layer water management system, intended for use over existing WRB or coated sheathing, of cavity spaces that are non-compressible and act as a furring matrix to promote enhanced drainage and drying, paired with improved installation efficiency. |
