Learn about building science, water intrusion, and how to protect your property
Your building envelope is the weathertight barrier that separates the interior from the exterior. It includes the roof, walls, foundation, windows, doors, and all connections and penetrations. A properly functioning envelope keeps water out, regulates temperature, and maintains air quality.
Water penetrating the envelope through cracks, gaps, or failed seals. Can cause structural damage and mold.
Uncontrolled air movement through envelope gaps. Increases energy costs and can cause condensation.
Moisture trapped in wall cavities from condensation or water intrusion. Leads to decay and mold.
Caulk and sealants deteriorate over time. Become brittle and lose effectiveness after 5-10 years.
Moisture creates ideal conditions for mold. Health hazard and expensive to remediate.
Untreated moisture causes wood rot and material deterioration. Can compromise structural safety.
Modern building science uses a layered defense approach: rain screen, drainage plane, air barrier, and vapor management. Multiple layers provide redundancy if one fails.
