FAQs about IEQc4.1 :

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?

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?

Has anyone experienced reviewers comments on Leveling Compounds or is the application more geared towards flooring systems? Most compounds are zero VOC but may contain Prop 65 chemicals if used in LEED for Healthcare or LEED 2012 eventually. Thanks!

I've never received a comment, but I report them under IEQ 4.2, yes, because they are applied on-site inside the weatherproofing barrier. I assume you're talking about Ardex and similar products.

Thanks for your reply, Marian. I just did a bit of homework and and Ardex indicates its Leveling Compounds are FloorScore certified.Check out: www.buildsite.com/dbderived/ardex/derived.../derivedC578209.pdf
