摘要:
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.

摘要:
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.
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.
摘要:
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.
摘要:
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.

摘要:
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.
