What Did I Miss? How to Properly Specify an Air Barrier System

by Ryan Dalgleish

Design and Construction documents are one of the first steps towards achieving an effective layer of airtightness to manage moisture and air movement. The importance of a proper specification cannot be understated and a well-articulated document will ensure that the owner is provided with materials, performance and quality.

The presentation will review some of the consideration and language that should be reviewed prior to developing a specification and will outline code requirements, performance requirements, what can be done for quality and ensuring material selection meets the intent of design and for crucial coordination with other components of the enclosure.

Learning Objectives:

1. Understand the various test methods for air barrier materials and assemblies as it relates to air, water, fire and other key requirements.
2. Analyze the other control functions for a wall assembly and determine if the air barrier also provides vapor control or water resistance.
3. Identify key language for 3-part specification to articulate performance standards, execution and quality requirements.
4. Define requirements for quality assurance and control and typical downfalls of specification language.

Trust but Verify: Quality Control for Your Air Barrier

by Ryan Dalgleish

Today’s building construction must overcome complex building materials, multi-layer construction/multiple trades, thinner construction, limited on-the-job training, higher expectations, tight schedules and the pressure to keep the cost as low as possible. In the past, building systems were simpler with fewer layers. That is no longer the case.

One way to help ensure a successful project is to incorporate some form of quality assurance and quality control. Quality assurance can be achieved through incorporating a quality management system for the air barrier sub-trade. Quality control can be implemented before the first square-foot of air barrier is installed and then throughout the installation process.

Learning Objectives:

1. Identify how to specify and use a variety of performance mock-ups to confirm design intent, sequencing, material compatibility and standards of installation acceptance.
2. Demonstrate various ASTM test methods for assembly air permeance, rain penetration, adhesion, density and thickness testing procedures.
3. Define key visual inspection methods used during the construction process for various air barrier materials utilizing site photos and proper corrective action.
4. List the top five field related installation issues found during site quality control audits using site photos and case studies to evaluate the installation of the air barrier application.

The Importance of Wall to Roof Connections for the Air Barrier

by Roy Schauffele

As more states, jurisdictions and the design community require air barriers, the issue of connecting the wall air barrier assembly to other building assemblies, such as below-grade, window systems and roofs need to be completely understood in order to design and construct a functioning building enclosure.

One of the most often missed or poorly executed details is the connection between the wall air barrier and roof assembly. With a myriad of roof systems, wall configurations and the growing number of wall air barrier products, it can be difficult to navigate the process in regards to what systems work best with each other and the chemical compatibility of these systems.

This presentation will focus on things to consider from a design standpoint, along with practical approaches to ensuring a robust connection is constructed and executed.

Learning Objectives:

1. Describe why the roof/wall air barrier intersection is critical to building performance in regards to moisture management and air leakage control and common design and field errors.
2. Discuss compatibility issues related to wall and roof air barrier components for the myriad of air barrier and roofing assemblies that exist on the market today.
3. Identify pre-construction coordination items to review and allocation of responsibilities to sub-trades for proper execution of connection.
4. Review requirements for detailing the roof/wall interface and the sequence of construction for most common roof/wall air barrier connections.
