From Siga headquarters in Switzerland, Matt Risinger explains the science of controlling both air and vapor in buildings. The elegance of this video comes, in part, from Matt’s clear way of summarizing, and prioritizing, the control strategies available to builders. He stands here on the shoulders of giants, namely Joe Lstiburek, whose work Matt has been a diligent student of for many years. He doesn’t hide this, but he also provides a helpful complement to his mentor’s work by succinctly capturing the key principles. It’s a sound introduction to the dynamics of heat and moisture flow through building assemblies.
If you’re interested in delving further, this video offers a helpful introduction to a number of JLC features, as well:
- Controlling Moisture in Mixed Climates by Joe Lstiburek and Joe Carmody
- Avoiding Wet Roofs (parts 1 and 2) by Peter Yost
- Avoiding Wet Walls by Clayton DeKorne
- A One-Way Vapor Barrier? by Ted Cushman
- The Last Word (We Hope) on Vapor Barriers by JLC Staff
Matt’s science lesson is also artfully woven with a look inside Siga, the Swiss maker of tapes and membranes designed specifically for controlling air and vapor in building assemblies. This “inside look” adds a layer of interest for veterans and novices of building science alike.
