A thermos-type insulation for your home? Consider these four factors: 1) Heat transfer. Vacuum insulation removes the air molecules from your space, eliminating conduction and convection heat transfer, leaving just radiation transfer. 2) The primary characteristic of a vacuum is its “hardness”, or its ability to maintain pressure. A thermos is cylindrical and able to keep its hardness well; a flat panel will not be able to do the same. 3) Cost and puncture concerns make vacuum insulation impractical, but possibilities improve when it comes to items like refrigerators and entry doors. 4) A new, more efficient and cost effective panel made by Dow Corning provides a better value, even without the vacuum feature.
