Comment | More

A free, two-part webinar series hosted by Durability + Design explores water vapor permeance of coating systems on building exteriors. Part one, held Feb. 24, defined permeance; part two, coming up April 13, will discuss how permeance can affect the performance of an entire wall assembly.

Specifying Architectural Coatings Series: Water Vapor Permeance: Why Does it Matter?” will be held from 11 a.m. to noon ET on Wednesday, April 13.

Register online for free. Participants are eligible for one AIA LU credit.

The webinar sponsor is BASF.

The webinar will discuss how permeance affects the performance of building wall assemblies.

A recorded version of part one, “Specifying Architectural Coatings Series: Water Vapor Permeance of Coatings: What Is It?” can be viewed here.

Learning Objectives

The second part of the series will cover:

  • The differences between “vapor drive” and “water-vapor permeance of coatings” in building wall assemblies;
  • How impermeable, semi-permeable and permeable paint systems affect the performance of a building wall assembly;
  • How climate zones impact water vapor permeance; and
  • The value of using WUFI in coating selection.

The webinar will also present the results of thermo-dynamic modeling undertaken using WUFI-Oak Ridge National Laboratory (ORNL)/Fraunhofer Institute for Building Physics (IBP) software.

About the Presenters

Harold F. DeCelle and Kevin Brown, from Pittsburgh-based coatings consultancy KTA-Tator Inc., will present the webinar.
