An insulating member comprises a body of rigid foam material having a first connecting edge surface and a second connecting edge surface, a groove formed into the rigid foam material of the body along the first connecting edge surface, and a tongue formed from the rigid foam material of the body along the second connecting edge surface. The groove, when viewed in a transverse cross-section, tapers from narrow to wide in a direction extending from its opening and into the body. The tongue, when viewed in a transverse cross-section, tapers from wide to narrow in a direction toward the second connecting edge surface. The tongue is bifurcated along its length into first and second ridges by a wedge-shaped void. A polymer coating of polyurea or polyurethane substantially covers the tongue and structurally reinforces the tongue allowing the first and second ridges to flex toward one another without breaking.

Pipe insulation formed as a flat board is disclosed. The pipe insulation has an inner region that is more compressible than an outer region.

A cellular glass system for an outer surface of a pipe. An insulation layer surrounds the outer surface of the pipe. The insulation layer has an outer surface and an inner surface and comprises cellular glass. A foam fills an annular space between the outer surface of the pipe and the inner surface of the insulation layer and is configured to limit water intrusion into the annular space and attenuate sound. The system may also include another insulation layer and another foam layer between the two insulation layers.

A method of manufacturing an insulation elbow can include placing raw material at a processing machine. The method can further include implementing, at the processing machine, insulation elbow processing instructions for creating a plurality of insulation elbow segments from the raw material. Each of the plurality of insulation elbow segments can correspond to the insulation elbow such that the plurality of insulation elbow segments are configured to be assembled to form at least part of the insulation elbow. The method can also include creating, at the processing machine, the plurality of insulation elbow segments from the raw material according to the insulation elbow processing instructions and placing the plurality of insulation elbow segments in a package.

The present invention relates to an insulating material protective cover for a valve unit. The insulating material protective cover for a valve unit, according to the present invention, comprises: a first split body including a first plate, first finishing chassis respectively coupled to both end portions of the first plate in the widthwise direction, and second plates perpendicular to the first plate and respectively coupled thereto; a second split body including a third plate, second finishing chassis respectively coupled to both end portions of the third plate in the widthwise direction, and fourth plates perpendicular to the third plate and respectively coupled thereto; and a third split body including a fifth plate, a second finishing chassis coupled to a first end portion of the fifth plate in the widthwise direction, a first finishing chassis coupled to a second end portion of the fifth plate in the widthwise direction, and a sixth plate perpendicular to the fifth plate and coupled thereto.

This application describes insulated panel systems with first and second encapsulated foam core panels having foam cores, coated with or otherwise encapsulated in a shell material. Front and back overlap members may be fixed to the first encapsulated foam core panel or the second encapsulated foam core panel to allow the insulated panel system to removeably cover a container around a perimeter of the container (i.e., in a lateral direction relative to the container). A drip edge and overlap member may be fixed to the first encapsulated foam core panel to allow the insulated panel system to removeably cover a container vertically along a height of the container (i.e., in a vertical direction relative to the container).
