Condensation

Due to increased energy efficiency in building materials and design, homeowners are occasionally troubled by condensation, which is characterized by moisture and/or frost build-up on glass or other cold surfaces within the home.

If condensation does occur, quite often the culprit is not leaky or improperly sealed windows, as long as the windows have been properly installed and maintained as described in our Care & Maintenance Guide. The window, instead, indicates that the problem exists elsewhere.

Chances are that there is excessive humidity (water vapor within the air) inside the house. When this water vapor encounters a cooled surface, it will condense on it and possibly form a frost. To eliminate this problem, check your ventilation or control the sources of humidity within your home.

Here are some independent sites that we have found to be very helpful in exploring the topic of condensation and offering advice:
