More on Low e "Solar" Windows

If you've been following along, you may have learned how important it is to have high a SGHC rating on your south facing windows in a passive solar house. I have also complained about how clueless American window manufacturers are on the subject.

All that is still true, but Martin Holladay of the GreenBuildingAdvisor has compiled a helpful list of the Canadian suppliers that understand the issue. Even though Home Depot may not have these windows, you should be able to get them shipped to you. Fiberglass frames and triple glazing also add value to your project, and are usually worth the extra money. Fiberglass ensures you won't need to replace them in your lifetime. Triple glazing not only reduces heat loss all the time, it prevents most condensation problems even when you live in Denver and crank up the humidifier when it's zero degrees outside.
