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
