That's true ... the point being that "insulation" is still necessary
regardless of which you use... whether it is the factory built-in
insulation between the exterior and interior panels of SIPS; or added to
the exterior in the field, as with CLT construction.

Why would you need more insulation with a 6" SIP???

Are you looking for an argument, or are you just being uncommonly
thickheaded on this subject?
