Gases possess poor thermal conduction properties compared to liquids and solids and thus make good insulation material if they can be trapped. In order to further augment the effectiveness of a gas (such as air), it may be disrupted into small cells, which cannot effectively transfer heat by natural convection. Convection involves a larger bulk flow of gas driven by buoyancy and temperat… WebbThe selection of thermal insulation material is based on its thermal conductivity, thermal mass, temperature of indoor and outdoor spaces, durability, cost, and other factors. …
