Window source

| Posted in Energy, Heating & Insulation on

I’m planning to build a passive solar designed house. I’m having difficulty finding a source for south facing windows (low u factor & high shgc). I’ve researched a couple dozen companies so far and H window is the only one I’ve found that sells them. Does anyone know of other sources? Thanks, Aeon
