Dupont Building Innovations

DuPont™ Tyvek® commercial air and water barrier systems offer the best balance of properties to help effectively seal the building envelope. By controlling air and water infiltration and allowing interior moisture vapor to escape, they contribute to more sustainable, durable and comfortable structures. And because they help reduce HVAC costs, buildings will operate efficiently, year after year. The DuPont™ Tyvek® Fluid Applied System is our newest commercial air and water barrier system. It offers outstanding protection for concrete, CMU, and many sheathing substrates used in commercial projects. The Tyvek® Fluid Applied System can be used as a stand-alone offering or integrated with Tyvek® Commercial Wrap® or Tyvek® CommercialWrap® D systems for projects where the wall assemblies require both fluid applied and mechanically fastened building wrap air and water barrier solutions.

DuPont is the only manufacturer to offer fluid applied and building wrap air and water barrier systems. Learn more by visiting

This webinar provides an update on the findings of a research project led by the Oak Ridge National Laboratory on the energy performance of air barrier systems.

Infiltration and exfiltration account for 20 to 30% of the cooling and heating loads in commercial and residential buildings. This study was designed to measure the efficacy of air barriers in reducing these loads. The webinar will address data on energy performance as well as moisture content that was compiled over a twelve month period.

This project is a collaboration between the Oak Ridge National Laboratory (ORNL), the Air Barrier Association of America (ABAA), and twelve of its members. Participants are eligible for one AIA LU credit.

Learning Objectives

1. How are air barriers being specified in the 2012 International Energy Conservation Code (IECC).

2. What are the variation of air barrier materials and systems that are available in the marketplace today?

3. How much energy improvement do you obtain from increasing the air tightness of your building envelope component?

4. Am I compromising the durability of my building envelope component by improving the airtightness?


Andre O. Desjarlais, Group Leader, Building Envelopes Group
Oak Ridge National Laboratory

A native of Woonsocket RI, Andre O. Desjarlais earned a degree in Aeronautics with an option in fluid mechanics from Boston University in 1973.

Mr. Desjarlais joined the Oak Ridge National Laboratory (ORNL) in 1991 as a mechanical engineer. In 1998, he was promoted to group leader of the Building Envelopes Group. In 2000, the group was increased to include the Building Materials Group and an additional staff member researching radon issues with buildings. In 2006, the group was grown again with the addition of the Building America research staff. This staff was later spun off into a new group in 2008.

Prior to joining ORNL, Desjarlais was Manager of Testing Services at Holometrix, Inc. (formerly Dynatech R/D Company). At Holometrix, Mr. Desjarlais oversaw the technical, marketing, and administrative performance of a contract laboratory and analyses business specializing in the thermal performance of materials and systems.

Desjarlais has been a Member of American Society for Testing and Materials (ASTM) since 1987 and serves on Committees C16 on Thermal Insulation, E06 on Building Systems, and D08 on Roofing. He is the past Chairman of ASTM Committee C16. He has been a member of ASHRAE since 1991, serves on Technical Committees TC 4.4 on Thermal Insulation and Building Systems, TC 1.8 on Mechanical Insulation Systems, and TC 1.12 on Moisture Control in Buildings, and is presently Chairman of TC 4.4 and Research Chairman of TC 1.8. Since 1992, Desjarlais has been a member and Past Director of the Single Ply Roofing Institute (SPRI) Technical Committee and Board of Directors.

He also has served as a Member and Director of the Roofing Industry Committee on Weather Issues (RICOWI) since 1993. Desjarlais is the ORNL representative and former Chairman of the Federal Roofing Committee and past Member of the National Fenestration Rating Council (NFRC).
