SYSTEM 2

3 5/8" CMU veneer

1" rigid insulation

7 5/8" CMU backup

This system is a cavity wall consisting of an exterior concrete masonry veneer and a structural CMU backup. The two wythes are anchored with horizontal joint reinforcement.. The joint reinforcement can be ladder tri-rod type, tab type, or adjustable. To resist shrinkage of the concrete masonry veneer, the selection of joint reinforcement should take into account the requirements for shrinkage control in the veneer. These exterior units should be integrally water repellent treated or coated after construction.
