摘要： A shaped body, preferably plate-shaped, for use as heat insulation, formed of (a) a finely distributed, powdery or fibrous substance, (b) a microporous casing, and (c) a gastight and watertight, metal-free casing. The shaped body is produced by drying a powdery or fibrous substance if necessary, optionally placing it into a microporous casing, optionally pressing and then optionally drying. Thereafter, the powdery substance is placed with the microporous casing into a gastight and watertight, metal-free casing. This gastight and watertight casing is optionally evacuated and sealed. Furthermore, a shaped article, preferably plate-shaped, for use as heat insulation, produced from (a) a finely distributed, powdery or fibrous substance with a water absorption capacity of 4 to 50% by weight at 23.degree. C. and 85% relative humidity, (b) a casing of two parts with asymmetric design which contains this finely distributed, powdery or fibrous substance, the first part of the casing being metal-free and concave in such a manner that it is completely filled by the preferably plate-like shaped article and the second part being metal-free or metallic and planar and connected to the trough in such a manner that a gastight and water-vapor-tight seal is assured and both parts having water-vapor-permeabilities between 0 and 0.2 g/m.sup.2 /d at 23.degree. C. and 85% relative humidity and gas permeabilities for N.sub.2, O.sub.2 and CO.sub.2 of in sum 0 to 0.5 cm.sup.3 /m.sup.2 d/bar at 23.degree. C.; the shaped article having the property of absorbing water up to an amount of 2 to 15% by weight without its thermal conductivity deteriorating more than 25%.
