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?

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

Elastocol 500 Soprema

Hi, I have read a lot of threads, I am pretty sure this product can be considered part of the weatherproofing and therefore not be included. It is a primer used to prepare the roof surface for the torch on membrane in green roofs. How would you classify the product under SCAQMD 1168 if it did apply to EQc4.1? I am leaning towards Sealant Primer Architectural Non Porous with a VOC limit of 775g/l? Any experience? thanks

Curtis, I would include this in the credit - it's a primer, not the membrane itself. What are you applying it to - is it non-pourous?

yes its a primer and non-porous, does that mean Sealant Primer Architectural Non Porous as I have suggested? thanks curtis
