NC-v4 EQc2: Low emitting materials
Table 5 in the Low-emitting materials credit reference guide identifies a category of "Ceilings, walls, thermal, and acoustic insulation. Does that mean:
a) Ceiling assemblies, wall assemblies , thermal insulation, and acoustic insulation?
or
b) "Ceiling insulation, wall insulation, thermal insulation, and acoustic insulation."

Are throw rugs subject to the credit requirements?
What are the adhesives and sealants to be included in the documentation?
Is there a VOC budget method for this credit?
What are the limits on the VOC budget method?
Do products applied to the weather barrier need to comply with VOC thresholds?
If one part of my multicomponent wall system is not compliant, can I still get full credit?

Answering my own question. LEED v4.1 is much clearer:
"The insulation material category includes all thermal and acoustic boards, batts, rolls, blankets, sound attention fire blankets, foamed-in place, loose-fill, blown, and sprayed insulation."

While this answer covers types of insulation required to meet LEM requirements, the question still remains: What is the extent of product types related to walls that need to meet LEM requirements?
LEED v4.1 has this language, specific to wall panels "The wall panels product category includes all finish wall treatments (wall coverings, wall paneling, wall tile), surface wall structures such as gypsum or plaster, cubicle/curtain/partition walls, trim, doors, frames, windows, and window treatments." Does this mean that if a wall covering is applied to a regularly constructed wall, it does not need to be included?
Should we assume anything adhering to a wall needs to meet LEM requirements?
