Since 1977, when Sweden introduced its stringent energy code, almost all new homes in Sweden have been equipped with triple-glazed windows. Here in the U.S., where energy codes are more lax, triple-glazed windows are still rare.

For a minority of U.S. builders, however — especially cold-climate builders of superinsulated homes — triple-glazed windows are considered essential. Since few U.S. manufacturers offer high-solar-gain triple-glazed windows, most Americans get these windows from Canadian manufacturers.

The first company is a multi-state regional retailer of building products. The second is a national green products manufacturer/installer. In both cases I was there to give my perspective on the green marketplace from a custom builder-custom remodeler’s point of view. It was my goal to show them just how different today’s green builder looks from the typical builder of the last generation.
