Abstract: The embodiments described herein relate generally to improved fit duct liner insulation for curvilinear ducts in HVAC, exhaust, or other similar gas flow systems. A duct liner insulation for a curvilinear duct may include an insulation board having a first major surface and a second major surface. The duct liner insulation further includes a plurality of rows of kerfs in the first major surface of the insulation board configured to allow the insulation board to flex in a direction of the width of the insulation board such that insulation board is foldable into a curvilinear configuration. Each of the kerfs has a v-shaped cross section with sidewalls extending from a kerf base portion at or near the second major surface of the insulation board to the first major surface of the insulation board. The sidewalls extending at an angle from 10 degrees to 20 degrees relative to each other.

Abstract: Some embodiments of the present technology may encompass pipe insulation systems. The insulation systems may include an insulation member having an inner surface and an outer surface. The insulation systems may include a protective cladding having an interior surface and an exterior surface. The interior surface of the protective cladding may be disposed about the outer surface of the insulation member. The interior surface of the protective cladding may include an embossed texture formed from a plurality of protruding features and a plurality of recessed features. The plurality of protruding features may extend at least 0.02 mm beyond the plurality of recessed features.

Abstract: An insulation product may include an insulation material. The insulation material may include at least one material selected from the group consisting of nonwoven insulation, aerogel insulation, mineral insulation, and foam insulation. The insulation material may include a first end and a second end positioned opposite the first end. The first end may include a protrusion. At least a portion of the protrusion may widen in a direction opposite the second end. The second end may define a cutout that substantially matches a size and shape of the protrusion. The cutout and the protrusion may be aligned with one another along a length of the insulation material.

Abstract: Described are rigid and semi-rigid polyvinyl chloride (PVC) films, layers, or sheets, and methods of forming the same. The PVC products includes polyvinyl chloride resin and at least one 2D filler incorporated at the micro- or nano-scale. The film can have a low water permeance, for example, lower than that of a traditional PVC film. The water permeance of the PVC film described in this invention is significantly lower than that of a PVC film specifically developed for pipe jacketing applications. Standard pipe jacketing applications use either PVC or metal jacketing in their systems. The invention described herein produces a finished PVC product with a low water permeance similar to that of the metal jacketing products specifically developed for pipe jacketing applications.

Abstract: A duct insulation product may include an insulation material and a moisture barrier material coupled with the insulation material. The moisture barrier material may form an outer surface of the duct insulation product. The moisture barrier material may include at least one closure flap along at least one side of the moisture barrier material. The closure flap may extend beyond a periphery of the insulation material along at least one side of the insulation material. At least a portion of an inner surface of the closure flap may include an adhesive material.

Abstract: A method of using a self-stick insulation. The method includes providing a piece of insulation product with an adhesive coating. The adhesive coating includes polystyrene-maleic anhydride (SMA) and/or polyacrylic acid (PAA); an alcohol amine; and at least one of a polyvinyl alcohol and a starch. The adhesive coating is then activated with liquid water. Once the adhesive coating is active, the insulation product is attached to a surface with the adhesive coating.

Abstract: Some embodiments of the present technology may encompass pipe insulation systems. The insulation systems may include an insulation member having an inner surface and an outer surface. The insulation systems may include a protective cladding having an interior surface and an exterior surface. The interior surface of the protective cladding may be disposed about the outer surface of the insulation member. The interior surface of the protective cladding may include an embossed texture formed from a plurality of protruding features and a plurality of recessed features. The plurality of protruding features may extend at least 1 mm beyond the plurality of recessed features.

Abstract: According to one embodiment, an insulation blanket for insulating a structure includes a first facer layer and a second facer layer. A plurality of intermeshed non-woven glass fibers are disposed between the first and second facer layers and a fumed silica insulating powder is also disposed between the first and second facer layers. The fumed silica insulating powder has an average particle size of between about 2 and 20 nanometers. The insulation blanket includes at least one exposed edge having a cauterized face that forms a barrier on the exposed edge to encase the fumed silica insulating powder within the interior of the insulation blanket, which minimizes degradation of the insulating value due to loss or shedding of the fumed silica insulating powder through the exposed edge. The cauterized edge has a depth of cauterized material of between about 0.05 mm and 3 mm.

Abstract: The present disclosure relates generally to duct liner insulation products for curvilinear ducts, and more specifically relates to methods and materials to universally fit duct liner insulation for lining oval ducts in air conditioning, heating, and ventilating (HVAC) systems. A duct liner insulation for a curvilinear duct is provided that includes an insulation layer configured to line an interior surface of a curvilinear duct when installed within the curvilinear duct. The duct liner insulation also includes an elastically deformable layer configured to compress the insulation layer against the interior surface of the curvilinear duct when installed within the curvilinear duct such that the insulation layer extends substantially uniformly around an inner periphery of the curvilinear duct.

Abstract: A passivating flexible insulation blanket positionable about a pipe includes an insulation core, an enclosing fabric, and a non-consumable passivator. The insulation core is substantially hydrophobic and includes a microporous material. The enclosing fabric fully encapsulates the insulation core to form a capsule or pouch about the insulation core. The non-consumable passivator is non-consumable such that there is no appreciable change to a mass of the non-consumable passivator after an extended time of activation. The non-consumable passivator is deposited into the insulation core and has a composition soluble in water. The non-consumable passivator includes a leachable component that leaches from the insulation core and is capable of neutralizing acidic components. The leachable component is water soluble and is capable of reacting with a surface of the pipe to form a protective coating on the pipe to aid in inhibiting corrosion formation on the surface of the pipe.
