Abstract: A building facade including an exterior envelope including facade elements, a rain barrier, profiled holding and supporting elements fixed vertically to floor edges, a thermal insulation system including a first insulating element in front of floor edges and a second insulating element on the inside, between floors, a vapor barrier, and an interior lining. The first insulating element is basically continuous across the surface of the facade, or is essentially free of air pockets, two adjacent breadths of the first insulating element being separated by a flat surface of the profiled elements projecting forwards of the floor edges.

Abstract: The invention relates to a method for producing a mineral fibre board which comprises a coloured pigment and whose at least one surface is provided with a non-woven coating made of a substantially black material. The inventive method consists in inserting the coating into a board production device, wherein said coating is embodied in the form of a fabric, which is based on a polyester with appropriate weight per unit square, not precoloured and not impregnated or provided with an additional adhesive agent introduced therein for adhering to fibre pads. A coloured mineral wool product provided with the same colour coating produced by the inventive method is also disclosed.

Abstract: A transparent, monolithic or laminated sheet material based on a methyl methacrylate homopolymer or copolymer, the laminated material having at least one of its two outer layers made of the methyl methacrylate homopolymer or copolymer, characterized in that the monolithic sheet of methyl methacrylate homopolymer or copolymer or at least one outer layer of methyl methacrylate homopolymer or copolymer of the laminated sheet has, in the region of the surface, over a depth of at least 50 nanometers from the surface, an increase in its average density of 0.1 to 1 g/cm3, the average density being determined by X-ray reflectometry.

Abstract: The subject of the invention is a process for depositing, especially continuously, on a glass ribbon (10) of a float line, a reflective layer (3) based on a metal whose melting point is less than or equal to the temperature at which the glass ribbon acquires dimensional stability. The deposition is carried out in a controlled atmosphere, this being inert or reducing, when the glass ribbon (10) has already acquired its dimensional stability, by bringing the surface of the said ribbon into contact with the metal (22) in pulverulent form or in molten form, the temperature of the ribbon during contacting being chosen so that the powder melts and coalesces, or so that the molten metal forms a sheet, at the surface of the ribbon, leaving a solid continuous layer when the temperature of the ribbon is at a temperature of less than or equal to the melting point of the metal.
