I am working on the low-emitting materials calculator and looking at the flooring system right now. I am a bit confused about the category that flooring grout falls into. For Option 1. Product Category Calculations, do we choose flooring as its category or should it be under the interior adhesive and sealants category? I suppose it falls into the flooring category since it is part of the flooring system. Let me know if I am wrong here. Thanks.
