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

porous or non-porous material

Hi, Our project is located in Japan. We usually classify tiles and stones to porous materials in our country. Porous material is defined as follows according to SCAQMD Rule1168. (59) POROUS MATERIAL is a substance which has tiny openings, often microscopic, in which fluids may be absorbed or discharged. Such materials include, but are not limited to, wood, fabric, paper, corrugated paperboard, and plastic foam. Which category, porous or non-porous, is appropriate for tiles and stones under LEED submittal?

I am not an expert or tiles or stones, but I do know that different materials vary in porosity; I would ask your sales representative.
