Full Description

1.1This guide describes design, specification, selection, installation, and inspection of new building wall systems, exterior deck and stair components, doors, windows, penetrations and sealant joints of wood and metal frame buildings, typically four stories or less, to minimize water intrusion.

1.2This guide does not address prevention of damage caused by water originating from the use of wet building materials or from indoor or outdoor humidity. Water from these sources can be important, and the potential for damage caused by water from these sources must not be overlooked in building design or construction.

1.3This guide does not address roofing systems, except when the surface of a deck also serves as a roof and at locations where roof systems interface with building walls.

1.4This guide does not address any type of barrier wall system.

1.5This guide does not address any exterior insulation and finish system (EIFS).

1.6This guide does not address foundation conditions where the bottom of a slab on grade or the grade of a crawl space is at or below the water table or subject to hydrostatic pressure.

1.7This guide is intended to supplement and not duplicate building code requirements.

1.8Maintenance, although important, is not covered in detail.

1.9Application of finishes, such as paint and sealers, may be important in the performance of some types of cladding; however, this is not covered in detail.

1.10This guide applies only to constructions with sheathing, which facilitates installation of the weather-resistive barrier and associated flashings in a common plane.
