SBR and rubber flooring

Yes, if you're avoiding carpeting with SBR backing then you would not be required to do that test, according to the letter of LEED. If you're using a rubber flooring product that probably has a high level of emissions, it seems like a loophole in the credit to ignore 4-PCH, though.

I have the same issue on a LEED CI 2009 project. We have a vapor barrier that the architect wants to add at the masonry walls exposed to the interior of one of the lab support rooms. The product - PPG Seal Grip - is classified as a sealer and under the 200 g/L voc limit for IEQc4.2. However, I see from the data sheet that it contains SBR. The project has already committed to option 2 for IEQc3.2 with an IAQ test but does not currently included the 4-PCH component. Should it now? Or is the requirement only for 'SBR carpet and fabrics'? In other words - does anyone know if LEED has closed this loophole?
