Condensation Problem
Condensation problems occur when warm, humid air meets cold surfaces and the moisture condenses into liquid. This often happens in poorly ventilated rooms such as bathrooms, kitchens or basements. Condensation can lead to various issues, including mould growth, moisture damage, and an unpleasant indoor climate.
Causes of Condensation Problems
-
Insufficient ventilation: In poorly ventilated rooms, moisture produced by cooking, showering or breathing cannot escape. This leads to higher humidity and thus condensation problems.
-
Thermal bridges: Thermal bridges occur where the building’s insulation is inadequate. These colder areas attract moisture from the air, causing condensation.
-
High humidity levels: High indoor humidity increases the likelihood of condensation forming on colder surfaces.
-
Temperature differences: Large temperature differences between indoor and outdoor air—especially during cold seasons—can encourage condensation.
Effects of Condensation Problems
-
Mould growth: Condensation creates ideal conditions for mould, which can lead to respiratory problems and allergies.
-
Moisture damage: Persisting dampness can harm building fabric, cause wallpaper and paint to peel, and lead to wood rot.
-
Unpleasant odours: Damp conditions can produce musty smells that degrade indoor comfort.
Prevention and Remedies
-
Improved ventilation: Good ventilation is key to preventing condensation. Regular airing and the use of extractor fans in bathrooms and kitchens help reduce humidity.
-
Insulation and sealing: Insulating walls and roofs and sealing windows and doors can help reduce temperature differences and thermal bridges.
-
Dehumidification: Using dehumidifiers helps control indoor humidity and prevent condensation.
-
Warm surfaces: Heating rooms and avoiding cold surfaces where moisture can settle are important steps in preventing condensation.
