Method for the manufacture of insulating bodies based on mineral wool. In the method, one side of a mineral wool body manufactured in a manner known per se is subjected to a vacuum and its opposite side is contacted with a clay slurry, e.g. bentonite slurry, whereupon the clay slurry is absorbed into the mineral wool, and finally the impregnated mineral wool body is dried at an elevated temperature. In an insulating body according to the invention, the fibers of mineral wool bonded with an organic bonding agent are oriented in a tubular body mainly against the radius and in a board-like piece mainly in parallel to the main planes of the board, the body contains clay material up to 40 percent by weight, its compressive strength with a compression of 5 % is at maximum 120 kN/m<2>, and its heat conductivity lambda 10 is 0.032-0.048 W/mK. |
