2.0703.1 Sealing/Isolating Exposed Fibrous Insulation in Areas with Routine Human Activity

Occupant Education and Access
Desired Outcome: 
Occupants protected from insulation particulate exposure
Fibrous Insulation Isolation

Fibrous insulation materials will be encapsulated on all surfaces facing spaces where there is routine human activity

Encapsulation materials will be fire rated, if applicable, to preserve the pre-retrofit fire rating of the building assembly, and/or as required by insulation manufacturer or relevant building code

Vapor permeability of encapsulation materials will be consistent with predetermined vapor retarder Vapor retarder A material that slows the passage of water vapor and contains a perm rating above 1 placement

Protect occupants from insulation exposure

Maintain fire rating of assembly

Protect building from moisture damage
