Each system within this guide is addressed specific to the Northwest region, including Washington, Oregon, and Idaho and considers local climate, codes, and building preferences and practices. The systems included within this guide have also been developed for application to occupied multistory, multifamily residential or commercial structures with typical indoor environments (e.g., ASHRAE 551–compliant spaces) in the Northwest region. Multistory applications of each system are recommended in the “Masonry Systems Comparison Matrix” beginning on page i-8. Although, some of the systems discussed within this guide may be applicable to structures with atypical indoor environments (e.g., natatoriums, fridge and freezer warehouses, unconditioned spaces, etc.), these applications are not the intended scope of the guide.
The information presented within this guide is not meant to be exhaustive of all system variations, product performance properties, or detailing approaches but rather represents a selection of the successful enclosure design and construction practices used in the Northwest region.
This guide is not intended to replace professional advice. When information presented here is incorporated into specification building projects, it must be reviewed by the design team and reflect the unique conditions and design parameters of each building in addition to conforming with local building codes, standards, and by-laws.
