Brick Veneer Steel Stud (BV-SS) Wall Systems and Insulated Composite Backup (ICB) Panels

Apr 12, 2010

Brick veneer over metal stud framing creates several challenges related to control of moisture originated from rainwater and vapor drive. This is especially true with systems that have multiple components and erectors to install the needed air, water, vapor and thermal barriers. There have been many reported water-related problems with multiple-component assemblies.

These barriers are more effectively achieved with one structural composite product and one installation through the use of specially designed insulated composite backup (ICB) panels. In this solution an exterior rain screen leads water down the steel face of the composite panel to drain at the base of the wall. Structural joints and factory seals, as well as closed-cell foam core material are placed on the exterior side of the stud cavity. Exterior insulation and high air and water resistance with minimal water entrapment, eliminating dew point and mold concerns are characteristics of the system. Specially designed clips allow for brick tie connections without compromising the system performance. This system is code-compliant and accepted by consultants in the wall industry.
