Expert Meeting: Cladding Attachment over Exterior Insulation
July 28, 2012
The purpose of this expert meeting, hosted by Building Science Corporation (BSC) is to support the Critical Milestone #1 identified by the Building America Standing Technical Committee: By end of 2012, have adopted code language defining the requirements for attaching cladding over typical thicknesses of insulating sheathing (i.e. 1”, 1.5”, 2”, and 4”) for both 16” and 24” o.c. framing.
The meeting focused on issues surrounding cladding attachment and performance of walls with exterior insulating sheathing. The intent was to examine these topics from an engineering design, laboratory testing, field monitoring, as well as practical construction perspective, with various interest groups such as architects, engineers, manufacturers (insulation, siding, and fasteners) and contractors. The meeting included the following topics:
- Gravity load resistance
- Wind load resistance
- Seismic load resistance (this topic is acknowledged, but no work in the area is currently known and is not intended to be discussed).
