Today’s building construction must overcome complex building materials, multi-layer construction / multiple trades, thinner construction, limited on-the-job training, higher expectations, schedule, and are generally cost sensitive. 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 through the installation process.
A variety of both quantitative, qualitative and visual inspection can be done on a performance mock-up and then the installed air barrier assembly to confirm conformance to project specifications.
A review of the key test methods used during the construction process and a demonstration of the type of testing equipment for both air leakage, water penetration, adhesion and material specific test methods.

 Learning Objectives

  1. Identify how to specify and use a variety of tests on your project to confirm design intent, sequencing, material compatibility and standards of installation acceptance.
  2. Through the use of testing equipment, 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. Determine Top 5 field related installation issues found during site quality control audits using site photo’s and case studies to allow attendees to evaluate the installation of their air barrier application.
