Ventilation and Moisture Readings

What Should Moisture Readings Be for Internal Walls?

Moisture readings for internal walls are critical in ensuring that the building is adequately ventilated and free from excessive moisture that can lead to structural damage and health hazards.

Moisture readings ideally should fall within a range that ensures the walls are neither too dry nor too damp. Dry walls can crack, while excessive moisture can promote mold growth, rot, and other issues.

• Recommended Moisture Readings: It is generally recommended that moisture readings for internal walls not exceed 15%. Readings between 5% and 15% indicate optimal conditions.
• Dry Walls: Moisture readings below 5% can indicate excessively dry walls. Dry walls are prone to cracking and can be more susceptible to damage.
• Damp Walls: Moisture readings above 15% indicate damp walls. Damp walls can foster mold growth, rot, and other moisture-related issues.
• Factors Affecting Moisture Readings: Various factors can influence moisture readings, including ventilation, indoor humidity levels, and leakages. Proper ventilation is crucial to regulate humidity and prevent excessive moisture accumulation.
