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?

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

Single ply roof membrane

In a greenroof application, if a single ply roof is use (we called it a "liner"), does it have to comply with the 450 g/L of VOC limit? Techically, it is on top of the building on the outside. And it is a waterproofing membrane. Since the "interior of a building" is defined as everything inside the waterproofing system we consider this product does not need to be compliant with the 450 g/L limit. Are we correct?
