FAQs about IEQc4.1 :

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?

Our project didn't use some common adhesive types, and our LEED reviewer asked about this. Are we supposed to justify not using certain adhesives in our documentation?

Is there a shortcut to the VOC budget method if you have just one product that is used minimally on a project?

Do products applied to the weather barrier need to comply with VOC thresholds?

How do I determine what application my product falls under?

NC-2009 IEQc4.1:Low-Emitting Materials—Adhesives and Sealants

Adhesive category for Foster 85-20

What is the appropriate category for Foster 85-20? Our contractor told us that it was Special Purpose Contact Adhesive. And how do we verify this?

"SPECIAL PURPOSE CONTACT ADHESIVE is a contact adhesive that is used to bond all of the following substrates to any surface: melamine covered board, metal, unsupported vinyl, Teflon, ultra-high molecular weight polyethylene, rubber and wood veneer 1/16 inch or less in thickness" while the product to information states: Foster®Spark-Fas Adhesive is a quick-setting, nonflammable, fire-resistive, synthetic elastomer adhesive used to adhere duct wrap, fibrous glass or mineral wool insulations (up to 6 lbs. density) to galvanized steel and aluminum air conditioning or hot air ducts, where a fireresistive dry film is required." VOC content - 162g/liter I believe this would fall into the classification of: 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." Max VOC 70g/l Has the adhesive been used? if not, I would search for an alternative...

This has been used and it does not meet VOC requirements it is the only adhesive that does not meet the requirements

You will need to consider using the VOC budget approach. http://www.leeduser.com/credit/NC-2009/IEQc4.1#gid-tab/14251
