I spent today learning about vapor diffusion, convection and air sealing at the company SIGA near Lucern Switzerland.
I have to say... I have a few weekness: to name a few it's timberframe buildings, good beer and being in a beautiful setting. Today had all three in one: I'm used to good beer and am regularly in beautiful settings, but I can't say that I've ever been in a manufacturing plant, complete with robotic packaging stations, that were all housed in a Timberframe. My TF Guild friends would be proud.
The class at Siga was insightful and filled the day with a really interesting subject still new to most of the US: how to build airtight without creating a breading ground for mold spores. I can't say that I ever thought I'd look forward to spending a day on that subject, but things change.:)
Happily, I got to spend some time with a PH Consultant from Latvia. It was interesting to hear that PH is gaining ground steadily in the Balitic region. He was here to take in all he can on airsealing for the same reason as me... 0.6 ACH. It's great to meet people from other parts in the world walking the same trail at the same time.
