Abstract:
The present invention concerns a method of making a mineral melt by burning combustible material in the presence of inorganic particulate material and thereby forming a melt, comprising injecting fuel, particulate mineral material and combustion gas into a circulating combustion chamber (1) through an inlet conduit (4) and combusting the fuel in the circulating combustion chamber (1) thereby melting the mineral material to form a mineral melt and generating exhaust gases; separating the exhaust gases from the mineral melt, collecting the mineral melt (9) and passing the exhaust gases upwards through an exhaust pipe (10) to a conduit (11) of a heat exchange system; and supplying particulate mineral material and a first portion of waste mineral wool into the conduit (11) and pre-heating the supplied material in the heat exchange system, and supplying a second portion of waste mineral wool with a water content between 5 and 25% by weight directly to the inlet conduit (4).
Abstract:
The invention relates to a method for manufacturing a mineral fiber-containing composite and the novel mineral fiber-containing element produced by that method.
Abstract:
The invention relates to a heat insulation element for insulating building facades, in particular for heat insulation composite systems, composed of a heat insulating board and a reinforcement mesh that can be penetrated by fastening elements, in particular plugs, wherein the reinforcement mesh is placed in the area of a large surface of the heat insulating board. It is the object of the invention to avoid the disadvantages of the state of the art and in particular to provide a heat insulation element which even in case of high tightening torques of the fastening elements does not excessively tends to be deformed into the direction of the building facade. This aim is achieved by a heat insulation element according to the invention, in which the reinforcement mesh is arranged as a component of an abutment at a distance to the surface of the heat insulating board and in which the reinforcement mesh comprises a surface area which is smaller than the area of the surface of the heat insulating board.
Abstract:
The invention relates to a method of making a particulate material comprising; providing mineral wool base material in a form having size at least 80% not more than 40 mm, subjecting the mineral wool base material to sintering by use of a pulse combustor and thereby forming a particulate material in the form of particles having size at least 80% not more than 20 mm. An apparatus for carrying out the method comprises means for size reduction of coherent mineral wool substrate and a reaction chamber in communication with a pulse combustor.

Abstract:
The invention provides a foamable composition comprising a foam pre-cursor and man-made vitreous fibres produced with a cascade spinner or a spinning cup, wherein at least 50% by weight of the man-made vitreous fibres have a length of less than 100 micrometres.
Abstract:
An insulation element for thermal and/or acoustic insulation of a flat roof or a flat inclined roof comprises a first layer made of mineral fibres, and a second layer made of at least one fabric, whereby the second layer is fixed to a major surface of the first layer by an adhesive. To reduce the adhesive costs and the risk of blistering the roof membrane at the application stage, the second layer is impregnated with a filler. The second layer in combination with the filler has a permeability allowing hot air gases to pass through the second layer and closing the second layer for the penetration of a glue or adhesive in the direction to the first layer.
