NC-2009 IEQc4.1: Low-Emitting Materials—Adhesives and Sealants
For an office application we have an air-supply plenum for conditioning the space, what is the maximum content of VOC allowed for the plenum sealing material?
Thanks in advance.

Do products applied to the weather barrier need to comply with VOC thresholds?
How do I determine what application my product falls under?
How is VOC % less water determined for aerosol adhesives?
Do grout and caulking need to be included, and if so, what is the application category?

USGBC addressed duct sealants in LI#5241 (http://www.usgbc.org/leed-interpretations?keys=5241): “Project teams may classify duct sealants under ‘Other’, as listed in the SCAQMD VOC Limits table.” For “Other” sealants SCAQMD-1168 allows up to 420g/L.
This LEED Interpretation aligns with a previously issued technical bulletin from the Sheet Metal and Air Conditioning Contractors’ National Association (SMACNA).
