We have a project installing solid wood, (untreated) for the window sills & some baseboards. The reference guide indicates the sills & baseboards would fall under the "walls" category (I think), which then might even follow the "built in cabinetry" (I think). Regardless, how does one treat this for emissions criteria? I doubt that it had emissions criteria at all, but it seems like a grey area in a way. Some of the sills are at floor level, while some are about regular height. Since the ceilings/walls/thermal/acoustic insulation category needs to be met 100% of all products, this one would ding us that category. Does anybody have experience with how to categorize this product or are we doomed without it having emissions testing? Thanks!
