Abstract: Pipe insulation assemblies (10) comprising tubular insulation (100) having a longitudinal slit (400), a jacket (110), releasable tape (120), butt sealant strips (600), and/or closing adhesives are disclosed. The jacket (110) overlays the outer surface of the tubular insulation (100). The jacket (110) has an extended lip portion (200) extending beyond the longitudinal slit (400). An adhesive (420) and an internal release liner (130) are located on the extended lip portion (200).

Abstract: An exemplary duct system includes a rigid duct member, a first duct connector connected to the rigid duct member, a first sealing member disposed between the rigid duct member and the first duct connector, a flexible duct, a second duct connector connected to the flexible duct, and a second sealing member disposed between the first duct connector and the second duct connector. The first duct connector is assembled to the second duct connector to compress the second sealing member and form a seal between the first duct connector and the second duct connector and thereby form a seal between the rigid duct member and the flexible duct.

Abstract: Various embodiments of apparatuses and methods relating to appliances are provided. In one embodiment, an appliance having a housing, one or more moveable components inside the housing, a drive assembly, and a dampening portion is provided. The housing includes, for example, at least one side wall and the dampening member is disposed at least partially between the drive assembly and the at least one side wall. The dampening portion includes, for example, a resilient material having at least one surface extending at least partially along the side wall and the drive assembly. The dampening member is configured to limit movement of the drive assembly during shipping and handling to prevent damage to the appliance. The dampening member stays with the appliance after shipping and handling to enhance performance of the appliance, protect the moveable component, or both.

Abstract: A duct liner includes an insulation layer and a facing. The insulation layer having a first edge surface, a second edge surface that is spaced apart from the first edge surface, and a first and second face surfaces that extend from the first edge surface to the second edge surface. The facing is disposed on the first face surface, such that the first face surface is entirely covered by the facing. The facing is disposed on the first and second edge surfaces, such that the first and second edge surfaces are entirely covered by the facing. Two spaced apart strips of the facing are disposed on and cover a portion of the second face surface adjacent to the first and second edge surfaces, such that a portion of the second face surface between the strips is uncovered by the facing.

Abstract: A method of manufacturing flexible insulated duct includes wrapping a substantially flexible tubular core with a layer of insulation. A substantially flexible outer layer is wrapped about the layer of insulation such that longitudinal edges of the outer layer circumferentially overlap to define a longitudinally extending seam. The overlapping longitudinal edges of longitudinally extending seam in the outer layer are bonded together, thereby forming the flexible insulated duct. The flexible insulated duct is then cut to a discrete length and installed at a job site.

Abstract: An insulated scuttle cover configured for placement within a building scuttle opening is provided. The insulated scuttle cover includes a scuttle panel configured to cover the building scuttle opening. The scuttle panel is further configured to be supported when positioned within the building scuttle opening. An insulated pouch assembly is positioned adjacent to the scuttle panel. The insulated pouch assembly includes insulation material sealed within a flexible pouch. The insulated pouch assembly is positioned on an attic side of the scuttle panel. The insulated scuttle cover is configured to prevent or substantially retard the flow of air passing through the building scuttle opening.

Abstract: A roof structure of a building that has a pair of rafter beams and a pair of eave struts extending between and connected to the rafter beams includes a plurality of first banding strips.
