Airtightness and Moisture Readings

Airtightness and moisture readings are important aspects of building science that contribute to the health and durability of a structure. Airtightness refers to the ability of a building to prevent air leakage, while moisture readings measure the amount of moisture present within building materials or the surrounding environment.

Moisture Readings for Internal Walls

Moisture readings for internal walls should ideally be within specific ranges to ensure structural integrity and comfort for occupants. Excessive moisture can lead to mold growth, structural damage, and deterioration of indoor air quality.

Factors Affecting Moisture Readings

• Airtightness: Airtight construction can trap moisture within walls, leading to elevated readings.
• Condensation: Moisture from indoor air can condense on cold surfaces within walls, increasing moisture content.
• Water leaks: Leaks from plumbing or roofing can introduce significant moisture.
• Ground moisture: Moisture from the ground can diffuse into walls through porous building materials.

Consequences of Excessive Moisture

• Mold growth
• Structural damage
• Decreased insulation performance
• Poor indoor air quality
• Health concerns for occupants

Importance of Monitoring Moisture Readings

Regular monitoring of moisture readings is crucial for early detection of potential problems. Elevated readings can indicate issues with airtightness, water leaks, or other moisture sources that need to be addressed promptly. Monitoring allows for timely intervention, preventing serious consequences and maintaining a healthy indoor environment.
