Flashing and Integration (Or Lack Thereof) of Windows with Weather-Resistive Barriers

Abstract: Lack of integration between windows and the building weather-resistive barrier is a systemic problem in many buildings that often leads to leakage within a wall system. Consequences of improper integration typically include leakage,...

Predicting and Modeling the Effects of Wall Cladding Ventilation on Sun-Driven Condensation

By: Liyen Kan, Joseph P. Pinon

Abstract: Many wall systems in North America incorporate a drained and vented air cavity behind the cladding. The purpose of this air cavity is to help control the flow of moisture through the wall system. Providing ventilation airflow through...
