Publication number: 20060179892Abstract: A process for manufacturing products of mineral wool, in particular monolayer and multilayer products of rock wool, wherein the mineral wool material of a primary mat (2, 2?) is mechanically comminuted by a combined beating and cutting process into mineral wool flakes (9) of a predetermined size and subsequently recombined for forming a final mat (4). By means of such a treatment of the mineral wool material, practically any inhomogeneities and imperfections in the primary mat (2, 2?) are eliminated, i.e., they are not present any more in the final mat (4). The process of the invention thus results in the final mat (4) in products having a three-dimensional, isotropic fiber structure, which brings about a noticeable economy in the bulk density, at an at least equivalent quality in comparison with conventional crimped products.Type: ApplicationFiled: February 17, 2005Publication date: August 17, 2006Applicant: Saint-Gobain ISOVERInventors: Johannes Horres, Joachim Mellem

Publication number: 20060162280Abstract: An acoustic insulating glazing unit including at least two substrate sheets, joined together around their periphery using a device that forms a sealed joint and a spacer frame, which device, with the two substrate sheets, defines a flat cavity filled with a gas.
