Why is There Condensation on My Ceiling?

Condensation is simply water that forms on cold surfaces. It’s a result of moisture-laden air that has come in direct contact with a cold surface. As a rule, cool air holds less moisture and warm air holds more moisture. Humidity (which most homeowners are familiar with) is the measurement of moisture in the air. The problems arise when condensation goes beyond the norm, and then its necessary to provide a fix. Here, some professional assessment might be required.

Every home has warm indoor air that rises naturally to the upper levels. Warm air is moisture-laden, and when it rises, it naturally cools and has less capacity to hold moisture. Finally, when the air touches a cooler surface, moisture is released as condensation. Too much condensation is symptomatic of some imbalance – whether it’s higher-than-usual indoor humidity, too many cold spots in the home, or just poor ventilation. Worst case, it could be all of the above.

Since warm air rises, and eventually reaches the attic, insulation professionals tend to focus on three priorities – sealing the area airtight; insulating to improve R-Value; and ventilating to ensure proper air circulation and moisture management. For the professionals at Great Northern Insulation, the combination of sealing, insulating and ventilating is key to effectively addressing condensation issues. It’s an approach that will tackle both air and moisture issues.

When the experts at GNI identify problems associated with moisture and/or condensation, one of the most effective solutions is Spray Polyurethane Foam. SPF, especially in the upper reaches of a home, is an application that does it all – it seals airtight; it diminishes airflow and air leakage; and it stops the accumulation of moisture. For GNI, this is a “system” approach that delivers several benefits at one time. And for the homeowner, it means the end to condensation problems.
