Moisture Barriers
What are Moisture Barriers?
Moisture barriers are essential components of building envelopes, designed to prevent water damage and protect the interior of a structure from moisture penetration. These barriers are typically installed beneath exterior cladding or roofing materials to prevent water from seeping into the building’s interior.
Importance of Moisture Barriers
Moisture barriers are crucial for the following reasons:
- Prevent Water Damage: Moisture barriers guard against water intrusion, which can lead to structural damage, mold growth, and compromised indoor air quality.
- Maintain Building Integrity: By preventing moisture penetration, moisture barriers preserve the structural integrity of buildings and extend their lifespan.
- Improve Indoor Air Quality: Moisture barriers help prevent the growth of mold and mildew, which can release harmful allergens and irritants into the indoor air.
Types of Moisture Barriers
Various types of moisture barriers are available, each suitable for specific applications:
- Asphaltic Roofing Felt: A traditional moisture barrier used in roofing applications.
- Polyethylene Sheeting: A durable and waterproof barrier commonly used beneath siding and exterior cladding.
- Self-Adhesive Membranes: These membranes offer exceptional adhesion and can be applied to irregular surfaces.
- Liquid-Applied Membranes: A liquid-based membrane that provides seamless protection and can be applied to various substrates.
Monitoring Moisture
Moisture Monitoring Equipment, such as moisture meters, is used to measure the moisture content of materials and surfaces. This equipment is essential for evaluating the effectiveness of moisture barriers and detecting potential moisture issues.
