They worked all week on the first floor windows, with great progress. It’s nice being inside with the light. The guys installing the window said Friday “nice windows”. They have never see a European style window before, let alone a window the meets the German Passive House standard. One of the challenges with the windows is the big ones are heavy, and two they have to be sealed tighter the regular windows be cause of the tightness that house has to be to pass the Zero Energy Ready Homes standard. And third they have to be installed in the middle on the 10″ thick wall.
