Storm Window Condensation

Condensation occurs where moist air comes into contact with a surface, which is at a lower temperature, such as a window. Condensation in houses is mainly a winter problem. Generally, it forms when warm moist air is generated in living areas and then moves to the colder parts of the home.

Condensation is encouraged by poor air circulation where stagnant air pockets form. Mold growth is the first sign that you have poor air circulation. One way to not only prevent mold growth, but also the condensation forming on your windows, is to install proper ventilation that is consistent through out the whole house.

It is common for condensation to form on single glazed windows. If you do own single glazed windows, you may want to invest in secondary glazing. But remember that you should not install the secondary glazing on all of your windows, for some ventilation is essential.

Other options include adding exhaust fans, a dehumidifier to your heating system, and having your heating and cooling system checked for blockages. If these suggestions do not solve your problem, you may need to install brand new windows. Consider new double-glazed windows or new wood or vinyl framed windows with spectrally selective glass.
