A mid-cavity triple glazed window (R-10!) install display by @innotechwindowsdoors at @passivehouseinstituteus conference last week. I’m hearing from multiple people that mid-wall is the most efficient place to install from a btu loss perspective. I like their support in between insulation. Interesting to see wood fiber insulation @timberhp.insulatebetter on this display too. #windows #tripleglazedwindows | Risinger Build
