Fungi resistant sheet, facing and faced insulation assembly

摘要

The facing of a faced building insulation assembly includes a central field portion that is or includes a kraft paper sheet. The kraft paper sheet contains a fungi growth-inhibiting agent that causes the kraft paper sheet to be fungi growth resistant. The kraft paper sheet may be perforated to provide the facing with a selected water vapor permeance, and/or may include a heat activated bonding agent that bonds the facing to the insulation layer of the assembly. The field portion of the facing may include a coating to stiffen the facing and/or decrease the flame spread and smoke formation characteristics of the facing.
