FAQs about IEQc4.1:
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?

Hi Allen -- Looks like no one got back to you on this yet. Joint compounds would fall under the IEQ 4.1 Adhesives & Sealants credit. Paper sheetrock tape does not have adhesive on it. Netted sheetrock tape has a light tack on it, but it's pre-applied during production. Neither type of sheetrock tape would need to comply with the VOC threshold requirements of IEQ 4.1, however, the mud and other substances used on site to adhere the sheetrock tape would need to comply.

Good morning.
In which 1168 category would joint compound be referenced?
Thanks.

Hi Bruce,
I am curious about this as well. Would it be this section?
(43) MULTIPURPOSE CONSTRUCTION ADHESIVE is any adhesive to be used for the installation or repair of various construction materials, including but not limited to: drywall, subfloor, panel, fiberglass reinforced plastic (FRP), ceiling tile, and acoustical tile. I guess it make sense that the compound is an adhesive for the joint tape, so multipurpose construction adhesive could apply.
Anyone else have input?
THANKS!!

Hi, Margie.
I guess if the joint compound is applied for the purpose applying tape it's an adhesive and could either be a multipurpose construction adhesive or a panel adhesive. Either way it shouldn't be a problem. I should add we've had some success with the pressure sensitive tape that isn't addressed by LEED but check with the AHJ before specifying. Where joint compound is used as a base coat on the face of the gyp board I'd assume it would fall under 1113. Then it would be classified as an "undercoater" with a VOC content. 200 g/L as per 1.1.2004 although I prefer to use more recent values.......
