New York Passive House builders are all scrambling to find high quality windows that meed the strict PH air tightness and insulation standards. With the exception of a few Canadian windows there just aren’t any US windows that meet these standards.
Almost all good windows come from Europe and the challenge for New York green builders is to first find these companies and second figure out how to get the windows over the water.
Eco Brooklyn’s last Passive House job used Austrian Reider windows, purchased from Thomas at Cembra.us. We were happy with them. They were very solid with a nice clean look.
