National Masonry Systems Guide: Northwest Edition

Created with the oversight of professional building envelope consultants, engineers, architects, experienced commercial masonry contractors, and other masonry specialists, the National Masonry Systems Guide: Northwest Edition is the product of decades of combined in-the-field masonry experience. RDH played a critical role in the guide’s creation in 2016 and in the 2018 document update, drawing on our long history of publishing guideline, policy, and best practice documents. We were also involved in presenting workshops to share the information in the guide with the industry.

Each of the guide’s eight chapters provides comprehensive design and construction detailing information for a primary above‑grade wall assembly composed of clay or concrete masonry as an adhered or anchored veneer or single-wythe concrete masonry unit (CMU) wall application. Each assembly is addressed specifically to the Northwest region (Washington, Oregon, and Idaho) and considers the local climate, codes, and building preferences and practices. At the end of each assembly chapter, 2D and 3D details and cutaway wall sections summarize the chapter content and illustrate the assembly’s use in real-world applications. Each assembly chapter also provides a pricing analysis to demonstrate the relative price per square foot.

Following the eight assembly chapters, a separate section contains additional information regarding thermal modeling parameters, published industry references, and product resources. Additional features of the guide include design and construction/installation checklists and other design considerations as well as an assembly comparison matrix to assist designers with assembly selection, including comparison categories for both commercial and/or residential applications.
