You may notice a trend in posts right now, as I'm on a bit of a VOC kick at the moment. (See indoor environmental quality (EQc4) posts on primers, phenol formaldehyde, and the interior/exterior issue.) The VOC requirements are quite vague, as good standard definitions of each category are hard for many products. Today I was asked to look at what VOC requirements there are for firestopping sealants. Though I don't have a definitive answer (<- this can't be stressed enough), after talking to a few people I feel like we're on the right track.
OSI Green Series Firestopping
I started looking for the VOC limit by searching through the CIR's to no avail. The project manager and I discussed and figured the best definition was "Architectural Sealant", yielding a upper VOC limit of 250 g/l. After looking online I noticed Grace has a great LEED summary of their Flamesafe products. The sheet didn't indicate what category they were listed as, but after talking to Craig Boucher, LEED AP I learned they also assumed that "architectural sealant" was the best category for the putty and silicone products. For the sprays they assumed that it would need to qualify as a non-flat paint under EQc4.2.
In any case none of the Flamesafe products are above 50 g/l total content, and Craig indicated that the products were already around those levels before they needed to be marketed as "green". Interestingly the OSI "green series" products listed above have a higher VOC level (listed at 55 g/l on Green Depot) than the "standard" product from Grace.
As I said before I think I'm right but can't be sure without your help (or dropping $220 on an official CIR). Please let us all know if you can add some certainty to this post by leaving a comment... Your help will be much appreciated!
