I require information about stack bond brick walls when used in brick veneer wall systems with stud wall back up and outboard mineral wool insulation
Brick veneer not laid in running bond is not discussed in the TMS 402/602 Building Code Requirements and Specifications for Masonry Structures. The most information available is on the Brick Industry Association website.
Specific to the installation, BIA recommends reinforcing the veneer with at least one wire embedded in bed joints. This is because stack bond has no in-plane or out of plane structural value. Make sure you use the proper veneer anchor system also. Wall ties are only allowed with wood stud backup. Veneer anchors are required with steel stud or masonry backup. Use brick with the least amount of variation in unit size. The alignment of the units follows the centerline of the head joints. The tolerance for the variation in length for a modular size FBX brick given in ASTM C216 is +/- 5/32". The variation in straight and plumb within the same parameters. All of this information must be written in the specification and a mockup should be required as well. Call me if you need to.
