What should moisture readings be for internal walls?
Excessive moisture in internal walls can lead to several health hazards and respiratory issues. It can create a breeding ground for mold and mildew, which release allergens and irritants into the air. These substances can trigger asthma, allergies, respiratory infections, and other health problems.
To ensure a healthy living environment, it’s crucial to maintain appropriate moisture levels in internal walls. The ideal moisture content depends on several factors, including the wall material, climate, and ventilation. However, generally, moisture readings below 15% are considered acceptable for internal walls.
If moisture readings exceed 15%, it indicates excess moisture buildup, which can lead to the following health hazards and respiratory issues:
- Mold growth: Excess moisture promotes mold growth, releasing allergens and irritants into the air.
- Respiratory infections: Mold and mildew spores can cause respiratory infections such as bronchitis and pneumonia.
- Asthma and allergies: Mold and mildew allergens trigger asthma and allergy attacks in susceptible individuals.
- Sick Building Syndrome (SBS): Internal wall moisture can contribute to SBS, a condition characterized by building-related health symptoms like headaches, fatigue, and respiratory irritation.
To prevent these health risks, it’s essential to address excess moisture in internal walls promptly. This may involve addressing ventilation issues, repairing leaks, or using dehumidifiers.
