I am in the process of choosing windows for a SIPS home to be built in northern Minnesota.
Here are the things I have heard:
Contractor- Don't waste your money on Triple-pane, the house is so well insulated that the difference in energy cost won't be worth it. Also, triple panes means two areas where seals can fail.
On this site- Energy savings is the same because the insulation advantage of the triple-pane is countered by the fact that it reflects more energy.
Friends - Dorwin (sp?) triple-paned have been great.
Friend - Really like H-window triple paned
I am looking for more advice. Thanks
