AbstractWhen a layer of air-permeable insulation material is installed such that there are air spaces in contact with both of its faces, upward forces cause an exchange between these air spaces. The air flows from the cold side to the warm side through the lower part of the insulation layer and from the warm side to the cold side through the upper part. The authors give the results of measurements they performed for the purpose of describing this effect and of drawing attention to the resulting increase in heat exchange.
