This document discusses ventilated rainscreen systems and compares Corium brick cladding to conventional brick veneer. Corium brick uses half the weight of traditional brick and lime-based mortar, requiring less water and structural support. It allows for continuous exterior insulation and avoids thermal bridges of conventional brick. Corium brick assemblies are lighter weight, easier to install, and better meet building code insulation requirements compared to traditional heavy brick veneer systems. Case studies show Corium brick provides design freedom, durability, and improved thermal performance over alternative cladding options.
