To achieve good sealing of a clearance between a spindle in a furnace of a type, such as a roller hearth furnace, heating heated objects while carrying them with a plurality of rollers installed in the furnace and a through-hole of a furnace wall and through-holes of the buildings of a bearing housing, or a clearance between a pipe extended between two buildings and exposed therefrom and a through-hole with simple installation work, while insulating the spindle or the pipe.
Heat insulating material made by bonding inorganic fiber and metallic foil and having flanges on both ends in a width direction is wound around the spindle or the pipe so that the inorganic fiber is on an outer peripheral face side of the spindle or pipe, fluororesin sheet material having flanges on both sides in a width direction is put on the heat insulating material, and overlapped parts of the flanges of the heat insulating material and the flanges of the sheet material are fastened to fixing flanges disposed to structures.
