Yes, the category is:"ARCHITECTURAL SEALANT OR SEALANT PRIMER is any sealant or sealant primer applied to stationary structures, including mobile homes, and their appurtenances. Appurtenances to an architectural structure include, but are not limited to: hand railings, cabinets, bathroom and kitchen fixtures, fences, rain gutters and downspouts, and windows."

I'd like to suggest different idea. LEED v2009 reference guide states that the targeted materials are all adhesives and sealants used on the interior of the building (i.e., inside of the weatherproofing system and applied on-site) and also, FAQ of Bird's eye view above states that the targeted materials are touched by the indoor air. Therefore, my suggestion is that the sealants used to separate glazings of double pain window, and also built inside of them, can be excluded from the calculation. I'm so sure that these kind of sealants are applied from factory.

I agree, SangHoon, I assumed that the work was being done on site - if it is not, then you statement stands.
