What section / title are you using for "Vaproshield" and "GreenGuard" type weather / air barrier sheet membranes?

072500 Weather Barriers if they are non-air-barrier tested products (Varposhield Wall Shield) and 072700 Air Barriers if they are tested for air permeance (Vaproshield WrapShield).

Depends on their primary use.

If they're being used solely as a weather barrier, whether or not they qualify as an air barrier, then 07 25 00 "Weather Barriers."

If they're a part of an air barrier system, but do double duty as a weather barrier, then 07 27 00 "Air Barriers."

I created a stand-alone section for VaproShield-type air barrier products to distinguish them from mod bit sheet & fluid-applied membrane types: 07 2715 Permeable Sheet Air Barriers.

I have also spec'd the non-air-barrier versions in 07 2500 Weather Barriers.
