Hammer & Hand’s Scott Gunter gives detailed walk-through of Wet-Flash system used on the Karuna Passive House project.
We were first introduced to Wet-Flash in late 2009 as we built the Vancouver Airport Home project. Cascadia Windows recommended it to us as the preferred method of installation for their fiberglass windows and we’ve found it to be a great pairing: high performance installation for high performance windows.
Incidentally, at about the same time we discovered Wet-Flash, Seattle Hammer & Hand project supervisor Dan Whitmore (then of Black Bird Builders) used the same system on his Courtland Place passive house. (See this recent post about our tour of Dan’s house last week.)
The Wet-Flash system has evolved a great deal since our first applications nearly three years ago. One new addition that’s been instrumental to the execution of the air-barrier system at our Karuna Passive House project is the Cat-5 liquid applied WRB system. (“Cat-5” as in Category 5 hurricane… the product’s designed to remain leak free under hurricane conditions.) Back in 2010 the Clackamas, OR based Building Envelope Innovations (BEI), the brains behind the Wet-Flash system, formed a partnership with Prosoco to market and distribute the system nationwide. “Wet-Flash” is now called Prosoco R-Gaurd.
