construction engineering; miscellaneous prefabricated structures. SUBSTANCE: multilayer panel has layer of encasement and intermediate one made of sheet material. Encasement is trough-shaped; intermediate layer is made of plane sheet members and trough-shaped ones to form sealed hollows. Trough-shaped members and encasement are placed in opposition relative to each other; plane sheet member is installed between trough-shaped member and encasement; heat- insulating inserts arranged over perimeter of trough-shaped members are placed on each side of one more plane sheet member. EFFECT: improved heat-insulating properties and strength at reduced thickness. 1 dwg
