The Technology

Our ultra thermal insulation is a nanoporous solid with both low density and small pores. Composition is amorphous silica and carbon in a three dimensional, highly branched network of primary particles (20-30 nanometers) which aggregate into larger particles. It has 30 to 70 nm pore sizes which are >100 times smaller than conventional insulation. It is this nano-scale porosity that gives our insulation its‘ excellent thermal performance. Gas molecules within the insulation experience the Knudsen effect“ which virtually eliminates gas energy exchange as gas molecules have a higher probability of colliding with the pore walls than other gas molecules. Solid phase conduction is low due to the low density and our proprietary infra-red opacifier greatly reduces radiation.

Comparison graphs of our insulation to other insulation such as polyurethane, expanded polystyrene (EPS), and fiberglass are illustrated above. Thermal conductivity and R value per inch are inversely related. Total heat flow resistance is the product of the R-value per inch and thickness. For example, a one inch thick insulation board vacuum panel provides the same resistance as over twelve inches of fiberglass or eight inches of polystyrene foam. The reported values are measured at 20°C and as with all insulation, will improve at lower temperatures and slightly degrade at higher temperatures.
