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,...

The Four Barriers - Concepts for proper wall design and construction

By: Brent Gabby, Vince Cammalleri

Contemporary building enclosures generally consist of layers of light-weight construction materials designed to prevent water penetration and control condensation, heat flow, and vapor flow. These layers are material assemblies that serve as four...

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...

5 [five] signs of facade problems

Just like in medicine, early detection provides the best chance of limiting losses when it comes to facade performance.  The top five tell-tale signs of problems are: cracking, displacement, leaks, material deterioration, and corrosion.
