FUNGI RESISTANT SHEET, FACING AND FACED INSULATION ASSEMBLY

摘要

A kraft paper sheet material includes a kraft paper sheet and an asphalt layer on one major surface of the kraft paper sheet that is partially absorbed into the kraft paper sheet. The asphalt layer has a fungi growth-inhibiting agent therein in amounts that result in the kraft paper sheet material having more fungi growth resistance than the kraft paper sheet without the asphalt coating layer. Water vapor transmission retarding facings for faced insulation assemblies and other water vapor transmission retarding coverings are made with kraft paper sheet material.
