Understanding interstitial condensation is crucial for building integrity and occupant health.
This hidden moisture issue can cause significant damage without visible signs.
What is Interstitial Condensation?
Interstitial condensation occurs when warm, moist air penetrates into the building envelope and condenses within walls, roofs, or floors.
Unlike surface condensation, it happens inside building materials, making it difficult to detect.
Causes of Interstitial Condensation
Key causes include poor ventilation, inadequate insulation, and thermal bridging.
When warm air moves through cold building materials, it cools below the dew point, causing moisture to condense inside the structure.
Preventing and Fixing Interstitial Condensation
Prevention requires a comprehensive approach: proper ventilation, vapor barriers, and thermal insulation.
Regular building inspections can identify potential issues early, preventing costly repairs.
