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.
