Abstract:
A system for assisting a user in the determination of a thickness of a layer of insulation, the determination being in compliance with design requirements for an object to be insulated, comprises: data input means, for receiving from the user, input data representing boundary conditions relating to the insulated object, the input data receiving means comprising predetermined insulation data storage means from which the user can select predetermined insulation data relating to the insulated object, means for calculating, on the basis of the input data, insulation thickness data to be output to the user; and display means for displaying the calculated insulation thickness data alongside a graphical representation of the predetermined insulation data, wherein the data input means comprises means for varying, by the user, the input data by selecting differing predefined insulation data items displayed in the graphical representation, to thereby vary the insulation thickness data to be output to the user.

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:
A corner bracket for assembly of two boards of a window mounting collar into a collar corner and for affixing said window mounting collar to an exterior face of a building façade so as to surround a window opening, said corner bracket; comprising two holding plates and two base arms, all four adapted for extending in planes parallel with and having back surfaces abutting the exterior face of the building façade in an affixed position of the collar. The bracket further comprises two flanges and two abutment plates adapted to extend away from said exterior face in an affixed position of the collar. Each abutment plate is positioned at a mutual distance from and in parallel with an associated said flange, each abutment plate being connected to the associated said flange via an associated said holding plate; so as to be able to hold said boards together to form said window collar corner, each board being received between a respective flange and its associated abutment plate.
Abstract:
The present invention concerns an insulating roof support assembly for a roof structure comprising a plurality roof elongated rafters spaced apart in a predetermined distance with insulation boards therebetween, wherein elongated mineral wool fibre insulation elements are provided on the top of each of the elongated roof rafters and elongated wooden elements on top of said insulation elements with at least one impermeable membrane between at least two neighbouring insulation elements sandwiched between the wooden elements and the insulation elements.
Abstract:
The invention provides an insulating element (1) for insulating a pipe, comprising: a partial pipe section (2) having an external convex face (3), an internal concave face (4) and first (5) and second (6) longitudinal surfaces extending between the external convex face (3) and the internal concave face (4), the partial pipe section (2) being formed of a polymeric foam composite material comprising a polymeric foam and discontinuous man-made vitreous fibres, wherein at least 50% by weight of the man-made vitreous fibres present in the foam composite material have a length of less than 100 micrometers.
Abstract:
The present invention concerns a method and an apparatus for making mineral fibre products by splitting an incoming primary web, said apparatus comprising a feeding conveyor for providing an incoming primary web of air-laid mineral wool, said feeding conveyor having a first direction of travel; a station for shifting the direction of travel of the primary web by receiving the primary web on a turning table and then transferring the primary web onto a receiving conveyor, where said receiving conveyor has a second direction of travel different to the first direction of travel; wherein a web splitter is provided at the downstream end of said receiving conveyor for dividing the incoming primary web into a first primary web and second primary web and wherein the turning table is shiftable in the first direction of travel.
Abstract:
A melt for use in the production of man-made vitreous fibres may be formed in a circulating combustion chamber (20) by melting particulate material. The material is collected in a base region (26) of the combustion chamber, where it can be heated using submerged heating means (40). The submerged heating increases the homogeneity of the melt within the melt pool (30), the increase in homogeneity being encouraged by a relatively long average residence time for mineral material in the chamber (20) of at least 15 minutes.
