Use this 3 part SimpleSpecs™ master specification to specify loose-fill insulation, vermiculite or perlite type for insulation installed in exterior wall assemblies.
Insulation is poured or pneumatically applied to wall assemblies. Since it is in loose form it completely fills the voids between framing members.
This type of insulation tends to settle long term so additional insulation may need to be applied to maintain the original thermal values.
