Exterior fogging

With modern, high-insulating, energy-saving insulating glass, in rare cases the opposite problem can occur: glass windows that fog on the outside.

The advantages of these panes, however, are so great that they should be used wherever possible. The new building codes require windows with good U-value in new buildings. Less heating means less exhaust and less pollution, and also reduces costs. In addition, equally as important, a pleasant indoor climate is obtained. Because cold radiation and drafts are eliminated, furnishings can be placed near the windows with far greater comfort.
