A process for depositing polycrystalline silicon on substrates, including foreign substrates, occurs in a chamber at about atmospheric pressure, wherein a temperature gradient is formed, and both the atmospheric pressure and the temperature gradient are maintained throughout the process. Formation of a vapor barrier within the chamber that precludes exit of the constituent chemicals, which include silicon, iodine, silicon diiodide, and silicon tetraiodide. The deposition occurs beneath the vapor barrier. One embodiment of the process also includes the use of a blanketing gas that precludes the entrance of oxygen or other impurities. The process is capable of repetition without the need to reset the deposition zone conditions.

A golf ball comprising a core, a barrier layer enveloping the core, and a cover enveloping the barrier layer, wherein the barrier layer has a moisture vapor transmission rate less than that of the cover, and the barrier layer comprises a thermoplastic or thermoset composition of microparticles dispersed in a binder.

A fibreboard, insulating, wall panel includes an integral air and vapor barrier of metal foil or metallized plastic film adhered to one surface of the panel. Panels are attached to a stud wall frame. Abutting panel joints are taped to provide a continuance vapor barrier. Increased thermal and acoustic insulation as well as structural integrity of the barrier is provided by the panel.

A new concept wall system is provided, wherein the Exterior Insulation and Finish System cladding is created using components with no water absorption, a very low vapor permeability and sealing properties, accommodated with an installation technology which extend the materials properties to the assembly, together with bonding and sealing the intersections and terminations, creating a Non-Permissive to water and vapor diffusion, Exterior Insulation and Finish System (NP-EIFS). The present invention relates to an EIFS cladding having two air and vapor barriers, one applied to the substrate, a continuous liquid membrane with sheathing joints sealed to be moisture barrier for inside vapors, and an exterior weather and vapor barrier which is created using closed cell extruded polystyrene insulation boards, special assembled with joints sealed, to create a non-permissive insulation envelope of the enclosure. Another object of the invention is to provide waterproof and air/vapor-proof details, a new concept of flashing and sealant application around windows/doors and other constructive elements to avoid thermal bridges and air leakage inside thermal envelope and wall assembly. Methods of installation are included.

The invention relates to a method of using high velocity metal forming to encapsulate a projection of a non-metallic article by a metallic article and a method of crimping terminal flanges defining an interstitial space therebetween, while trapping a vapor barrier element between the terminal flanges, thereby hermetically sealing the interstitial space.

The present invention provides a novel technology and a novel material having excellent pliability, gas barrier properties and water resistance, for the technical fields of packaging materials, sealing materials, electric insulating materials and the like, the present invention relates to a film of a material having a denatured clay as a main constituent thereof, wherein (1) the film comprises a denatured clay and an additive, (2) the weight ratio of the denatured clay is not less than 70% relative to total solids, (3) the film has gas barrier properties and water-vapor barrier properties, (4) the film has heat resistance, (5) the film has water resistance, (6) the film has sufficient mechanical strength to be used as a self-supporting film, and (7) the film can be formed on the surface of metals, plastics, rubber, paper and the like, and the present invention can provide a material comprising the denatured clay film in which denatured clay particles are highly oriented and which has excellent heat resistance, excellent pliability, excellent gas barrier properties, excellent water-vapor barrier properties, and high water resistance.

Low rise, user friendly latex foams for sealing insulative cavities of a building are provided. The foams may be applied to the interface of the sheathing and the studs within the insulative cavities to reduce air leaks. The latex foams may also be applied to the face of the studs to obtain an additional seal against air infiltration. The foam can be used to affix fiberglass batts, batt flanges, and vapor barriers to the framing without mechanical fasteners. A tackifier may be added to impart an adhesive quality to the foam. The tacky nature of the foam permits the drywall or vapor barrier to be repositioned without damage. Drywall is held onto the face of the studs by the tacky foam while mechanical fasteners are inserted to permanently affix the drywall to the framing. The compressive nature of the foam permits drywall to be attached without significant bowing or detachment.

The present invention is directed to multi-layer golf balls having at least three core layers, at least one cover layer, and at least one intermediate layer between the core and the cover layer that acts as a vapor barrier. Advantageously, the at least three core layers have a hardness gradient that either increases or decreases toward the at least one intermediate vapor barrier layer.

A chicken or fowl grow out facility utilizes a ventilated floor assembly including a ventilated floor through which liquid and gas can flow, but which retains manure and other solids deposited thereon, and a bottom floor plenum underneath the ventilated floor. A liquid and vapor barrier sheet preferably covers the ground surface underneath the floor assembly which together insulate the high temperature of the grow-out facility from the heat sink effect of the lower temperature ground. Conventional tunnel ventilation of the chicken house through the ends of the house creates a negative pressure inside the house relative to the outside environment which is vented to the floor assembly plenum. As a result of this tunnel ventilation and negative pressure, moisture in the manure from urine and otherwise evaporates into the air in the growth chamber and floor assembly plenum to effectively keep dry the manure retained on the floor and reduce ammonia formation and pathogen growth.

A faced fibrous insulation having a facing on one or more surfaces of a fibrous insulation material is provided. The facing provides improved surface quality, high and controlled adhesion, and is easily manufactured. The facing of the present invention includes a pre-applied adhesive that is heat activated to provide adhesion to the fibrous insulation. The facing may be input into the glass fiber forming section of a fibrous insulation production line. Alternatively, the facing may be applied to the uncured pack prior to curing or applied to the cured fibrous insulation. As another alternative, a vapor barrier layer may be attached on a surface of the insulation opposite the facing.

A sound barrier membrane comprises of a decoupling layer, a barrier layer and a dampening layer. The membrane also provides crack isolation, and acts as a vapor barrier. Numerous materials are disclosed which can be used to create these layers. Methods for assembly of the sound barrier membrane are also disclosed.
