Moisture Control and More with Spray Foam Insulation

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 insulation’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.

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.

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.

Continuous Insulation - Spray Polyurethane Foam vs. Rigid Foam Board

The design of exterior wall assemblies has become increasingly focused on performance for greater energy efficiency and resistance to air and water penetration. The 2015 International Energy Conservation Code and ASHRAE 90.1 now requires insulation that is continuous in wall assemblies, (i.e. not interrupted by studs, framing, etc.) in all eight climate zones within the United States. This push for continuous insulation in exterior wall assemblies is also reflected in green building standards and the desires of building owners to reduce energy costs.

In this presentation, we will look at the performance, installation and cost advantages of medium density spray foam insulation compared to the commonly used rigid foam board in continuous insulation applications.
