Are tapes covered under this credit?

These tapes are not covered by the credit, no.

EQ 4.1 and 4.2 primarily address products that are applied as a liquid or semi-liquid material, then evaporate to become a solid or semi-solid material. In many conventional paints/coatings/adhesives/sealants, the off-gassing of volatile organic compounds arebe a big part of this evaporation process. By definition, VOCs are "volatile" because they change from a liquid to a gas when they come into contact with oxygen at room temperature. Once they become gaseous, we breathe them in, and they can cause us a host of nasty short- and long-term health problems. The adhesives on things like duct tape aren't addressed in this credit because they don't typically contain the same types of volatile solvents that create health problems. Because these tapes are typically low-VOC, we don't have to track them for LEED in the same way that we have to for products that are conventionally high-VOC. This is a lay person's understanding of the science -- I would welcome a more technical response from anyone more savvy with this issue.
