Frequently Asked Questions

The CondenStop fleece absorbs, stores and releases significant quantities of moisture when condensation would normally occur. When the temperature of a metal roof drops below the dew point, the CondenStop fleece will absorb and store the condensing water vapor. The absorbed water will evaporate again into the ambient air under appropriate temperature and ventilation conditions.

When there is a temperature difference between inside and outside a building, condensation can form on the interior of cold metal panels – it is a natural effect.
