Abstract
A kraft paper sheet contains and/or is coated with a fungi growth-inhibiting agent that causes the kraft paper sheet to be fungi growth resistant. The kraft paper sheet alone or as part of a layered sheet material is used as a central field portion of facings for various faced building insulation assemblies. The facings, as part of an insulation assembly, are fungi growth resistant; may be perforated to provide the facing with a selected water vapor permeance; and/or may include a bonding layer, such as a heat activated bonding layer, that bonds the facing to an insulation layer of the assembly.
