Abstract: The present invention pertains to a rear-ventilated building facade with a load-bearing external wall, with an insulation layer formed from insulation panels and with a facade cladding, wherein the facade cladding is installed by means of a load-bearing structure, forming a rear ventilation gap, at a spaced location from the insulation layer, and wherein the rear ventilation gap is interrupted in the vertical direction by at least one fire barrier, which is configured as a mineral wool panel. It is characterized in that the at least one fire barrier extends over the entire width of the rear ventilation gap, and that the at least one fire barrier has at least one opening extending in the vertical direction in the area of the rear ventilation gap. The present invention further provides a process for manufacturing a rear-ventilated building facade.

Abstract: A method of making a board or mat, includes forming a liquid slurry with solids including inorganic fibers and cellulose fibers, forming a web from the slurry on at least one foraminous element, extracting water from the web, and drying the web to make a product, wherein the pH of the liquid slurry including the inorganic fibers and cellulose fibers is in the pH range of 2-6 and wherein the cellulose fibers have a Schopper-Riegler index of ?50 according to ISO 5267.

Abstract: In a method for curing mineral wool that is mixed with binder through microwaves, generating additional heat through installation of microwave active substances is performed through curing the binder material.

Abstract: The invention relates to a method for manufacturing vacuum insulation panels with a fiber core, comprising the steps of: providing a core blank of fibers, compressing the core blank to a predetermined final thickness for forming the core, evacuating a foil sleeve enclosing the core up to a pressure of ?1 mbar, and sealing the foil sleeve. The method according to the invention is characterized by the fact that, in the compression step, the core blank is arranged between two cover elements and is mechanically compressed therebetween, that the core is kept under compression pressure until the foil sleeve is sealed, and that the compression step is performed at the place of manufacture at room temperature without thermal impact. Thus, a method for manufacturing vacuum insulation panels with a fiber core can be improved such that it can be performed with reduced energy requirement and yet the insulating effect of the vacuum insulation panels does not suffer therefrom.
