Abstract: A fungi resistant asphalt is combined with a base sheet to form a fungi resistant asphalt containing sheet material. Typically, the base sheet is a fibrous base sheet that, by itself, may or may not be fungi resistant. The fungi resistant asphalt is at least partially absorbed by the base sheet to form the fungi resistant asphalt containing sheet material and typically forms one or both major surfaces of the fungi resistant asphalt containing sheet material.

Abstract: An underlayment for supplementing one or more physical properties of wall, ceiling, and floor construction components is used to in a wall, ceiling, or floor assembly that may be fabricated on site. The assembly includes: first and second wall, ceiling, or floor construction components which each have physical properties and an underlayment component which has at least one supplemental physical property for supplementing the physical properties of the first and second construction components. The construction components may or may not be secured together with the underlayment sandwiched between the second and first construction components to form a wall, ceiling, or floor assembly with the supplemental physical property or properties of the underlayment. The supplemental physical property or properties of the underlayment may include, but are not limited to, latent storage of thermal energy, sound transmission reduction, and/or burn through resistance.

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.

Abstract: 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.

Abstract: A faced building insulation assembly includes a first facing forming a first major surface of the assembly with a central field portion having one or more spunbond continuous polymeric filament mat layers. Preferably, the facing is fungi growth resistant and has a selected water vapor permeance rating as applied to an insulation layer of the assembly. The facing may also include one or more polymeric film layers, a fungi growth inhibiting agent, a pesticide, and/or a heat activated bonding agent that bonds the facing to the insulation layer of the assembly. The insulation assembly may also include a second facing forming a second major surface of the assembly that has a water vapor permeance rating equal to or differing from the first facing.

Abstract: A flexible nonwoven mat of polymeric fibers is liquid water transmission resistant and is particularly well suited for use as a prefabricated building construction underlayment. The polymeric fibers may be standard polymeric fibers or sheathed polymeric fibers that have fiber sheaths with a lower softening point temperature than the softening point temperature of the fiber cores. Preferably, the polymeric fibers are spunbond fibers and are bonded together through the application of heat and pressure. Where the fibers are sheathed fibers, interstices of the nonwoven mat are at least partially filled by a portion of the polymeric material of the sheaths that is dispersed into the interstices to reduce the porosity of the mat.

Abstract: A method of applying dry or low moisture fibrous thermal insulation by spraying an air entrained stream of pieces of fibrous insulation into cavities in a structure in which at least the largest area wall of the cavity is at least partially coated with a pressure sensitive adhesive, including vertical wall cavities, without having to use any insulation securing means is disclosed. The pressure sensitive adhesive is applied to at least part of one or more walls of the cavity and allowed to form a tacky surface prior to spraying in the pieces of fibrous insulation. The resultant just installed insulation, because of its low moisture content, requires either no drying time or less drying time than conventional blown in insulation before wall board or other facing material is applied without fear of mold forming.

Abstract: A faced fibrous insulation assembly includes: a fibrous insulation blanket whose fibers, preferably, are bonded together with a formaldehyde free binder; a facing formed by a kraft paper sheet material; and an asphalt coating layer on the inner surface of the facing that bonds the facing to the fibrous insulation blanket. The asphalt coating layer contains an odor-reducing additive in an amount sufficient to substantially eliminate odor that would otherwise be emitted by the asphalt coating layer without adversely affecting the adherent qualities of the asphalt coating layer. Preferably, the facing and the asphalt coating layer are fungi growth resistant.

Abstract: The facing of a faced building insulation assembly includes a central field portion that is or includes a kraft paper sheet.

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.

The first major surface the liner insulation has a low porosity or air and/or liquid impervious surface layer. The surface layer is formed by melting and consolidating fibers at and adjacent the first major surface of the blanket core or by coating the first major surface of the blanket core with a polymeric coating. The liner insulation exhibits a flame spread/smoke developed index of ?25/50.

The facing may include a fungi growth-inhibiting agent, be perforated to provide a selected water vapor permeance, and/or may include a heat activated bonding agent. The facing may have lateral tabs that are transparent, sufficiently open to enable wallboard to be directly bonded to framing members overlaid by the tabs, and/or of greater integrity than the field portion of the facing. The field portion of the facing may include a coating to stiffen the facing, inhibit fungi growth, and/or decrease flame spread and smoke formation.

Abstract: Permeance ratings of a variable perm sheet material, facing, and faced building insulation assembly vary with ambient humidity and/or temperature. In the insulation assembly, a facing is bonded to a major surface of an insulation layer. A central field portion of the facing, as bonded to the insulation layer, has variable water vapor transmission properties that vary from a relatively low permeance when exposed to ambient conditions of low humidity to a relatively high permeance when exposed to ambient conditions of high humidity. Preferably, the facing, as part of an insulation assembly, is fungi growth-resistant and may include a bonding layer, such as a heat activated bonding layer, that bonds the facing to an insulation layer. The sheet material may be embossed to affect its water vapor transmission characteristics.
