A thermal insulation composite includes at least a first metallic skin sheet, and a plurality of non-combustible metallic filaments randomly interlocked to form a wool and affixed to said first skin sheet. A second metallic skin sheet may be affixed to said wool and said first sheet, or the second skin sheet may be a surface of the structure to be insulated. A fluid is present in the interstices of the filaments and in the zone between the skin sheets. Each of the filaments has a significant len...

An insulation cutter receives a supply roll of insulation material, unrolls and cuts the material to single or plural preset widths and then cuts the material to a predetermined length. Special feeder arrangements allow the operator to perform the unrolling of the material and the transverse cut-off from either side of the machine and with minimum work aisle obstruction during periods of inactivity.

An insulation material which comprises: A. a major amount of 1,2-polybutadiene; B. from 10 to 150 parts by weight of a styrene or styrene derivative per 100 parts by weight of 1,2-polybutadiene; C. from 15 to 150 parts by weight of 2,4,6-tribromophenylacrylate per 100 parts by weight of the mixture of 1,2-polybutadiene and styrene or styrene derivative; and D. from 100 to 300 parts by weight of talc powder per 100 parts by weight of 2,4,6-tribromophenyl acrylate.

In order to provide an insulation system for internal thermal insulation of a pressure chamber which can be subjected to pressure by a gas flow, the system being constructed for arrangement at an inner surface of an outer jacket of the pressure chamber and comprising at least one layer of insulating material, whereby good thermal insulation can be obtained with little maintenance work, it is proposed that the insulation system should comprise means for equalizing pressure between the insulating ...

The present invention is directed to a unique thermal insulation panel. More specifically, the present invention is directed to a vacuum insulated panel formed of a highly impermeable evacuated envelope that is supported by a thermal barrier made of a macro-structural support structure having a cell or void size of 0.5 micron or greater. Preferably, the panel includes a getter material. Further, the present invention is directed to a thermal insulation barrier of a macro-structural structure. Pr...

An insulation blanket for a pipeline, comprising at least one insulating cell, wherein the or each insulating cell comprises a protective layer and an insulating layer.

Insulation blankets featuring a thermoplastic polyolefin protective covering.

The insulation barrier is made with a flexible foam polyethylene substrate and a film which is secured to at least one side of the substrate and which extends from at least one lateral edge of the substrate. The insulation barrier may be supplied in roll form or in panel form. In one embodiment, the film may be provided with a plurality of small holes to permit moisture vapor to pass through under a differential pressure on opposite sides of the barrier. In still another embodiment, the substrat...

A non-woven mat of fibrous thermoplastic insulation is produced by melt blowing recycled polyethylene teraphthalate (PET). The PET is melted, pressurized and extruded from an extrusion head into substantially continuous fibers that are subjected to turbulent high velocity air that attenuates the fibers. The fibers are then collected on a collection device building up a non-woven mat. The collection device is spaced from the extrusion device forming a flight path for the fibers that is sufficient...

An insulation system for metal buildings, having a roof structure formed by roof panels supported on parallel, relatively narrowly-spaced purlins which are, in turn, supported on parallel, relatively widely-spaced main support beams, comprises a plurality of adjacently positioned strips of insulating material suspended below the roof structure so as to form a relatively flat and continuous surface. The strips of insulating material are supported on a system of insulation support tube strings sus...
