An insulating core material for a refrigerating appliance includes a plurality of insulating glass spheres, wherein a plurality of interstitial spaces are defined between at least a portion of the insulating glass spheres of the plurality of glass spheres. A coating material is applied at least to the outer surface of the insulating glass spheres, wherein the coating material modifies the outer surface to define a retaining outer surface of each insulating glass sphere of the plurality of glass spheres. A secondary insulating material is combined with the plurality of insulating glass spheres, wherein the secondary insulating material is at least partially retained by the retaining outer surfaces of the insulating glass spheres to occupy the plurality of interstitial spaces.

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.

An objective of the present invention is to provide a pipe through which fluids can flow, in which thermal insulation in a space between an inner wall and an outer wall is achieved at low cost and high performance. The thermal insulation pipe of the present invention is a thermal insulation pipe formed by a double wall pipe of an inner pipe and an outer pipe. A thermal-insulating material to be filled in a space between the inner pipe and the outer pipe is made from an aerogel having a three-dimensional network structure with a framework constituted by a cluster of aggregation of primary particles. The thermal-insulating material includes fine particles having a three-dimensional network structure with a framework of the primary particles. A preferred form of such a thermal-insulating material is weakly bonded aerogel ultrafine particle generated by crushing at ultra-high speed a low-binding ultrafine aerogel generated from an aerogel with aging conditions during manufacturing process set to a low temperature and short time period.

Insulated portable spas and processes for insulating spas are described herein. The processes can include filling the undercabinet cavity of the spa with insulative fiberglass while the spa is in an upright position. The insulative fiberglass can be blown-in through sidewalls of the box frame. The portable spas can include an insulative air barrier at the bottom of the spa.
