Definitions
- the present invention relates generally to multi-layered reflective insulating composites and a method of fabricating those composites.
- the present invention recognizes the importance of recognizing the behavior of mid-range infrared (IR) as a form of electromagnetic radiation other than x-rays, visible light, or radio waves, for example.
- IR infrared
- plastics In plastics, a result of this is that relatively simple, linear polymers using a few elements like polyethylene or polypropylene are nearly transparent to IR whereas plastics including more complex, non-linear polymers using many elements like polyurethane or polyetherimide are very opaque (or absorbent). This often remains true regardless of visible appearances which, again, may differ greatly.
- the present invention comprises a low density, thermally insulating multi-layered reflective insulation system.
- the multi-layered reflective insulation of the present invention comprises a plurality of layers, including, but not limited to, a combination of any number of the following layers disposed on each other: scattering optics, multi-layer insulation, microsphere film, and polyblend foam.
- US 44421 65 A to Gebhardt, Joseph J., et al., entitled “Low-Density Thermally Insulating Carbon- Carbon Syntactic Foam Composite”, discloses an insulating composite comprising a syntactic foam material, pyrolytic graphite, and a boron in layer which enables the composite to reflect infrared energy.
- Composition discloses an insulating syntactic foam composition.
- the present invention provides a low density, thermally insulating multi-layered reflective insulation system that is easy to install, offers increased R-value resulting in increased insulation, and cost effective.
- the present invention comprises a multi-layered reflective insulation system comprising a first protective layer; a first scattering optic layer; microsphere film layers; a polyblend foam layer; a second scattering optic layer; and a second protective layer.
- the present invention also comprises a method of manufacture of a multi-layered reflective insulation system comprising a first protective layer; a first scattering optic layer; microsphere film layers; a polyblend foam layer; a second scattering optic layer; a second protective layer; securably disposing the layers on top of each other; and securably attaching the layers.
- FIG. 1 illustrates a partial sectional isometric view of the multi-layered reflective insulation system of the present invention
- FIG. 2 illustrates a partial sectional view of one embodiment of the embossed tile pattern of the scattering optic layer.
- the term “horizontal” as used herein is defined as a plane parallel to the plane or surface of the insulation system, regardless of its orientation.
- the term “vertical” refers to a direction perpendicular to the horizontal as just defined. Terms, such as “above”, “below”, “bottom”, “top”, “side”, “higher”, “lower”, “upper”, “over”, and “under”, are defined with respect to the horizontal plane, as shown in the figures.
- the term “on” means that there is direct contact among elements.
