Patent number: 10183470Abstract: A flame-retardant composite glass including a plurality of glass panes and a flame-retardant intermediate layer that is arranged between two first glass panes and includes a flame-retardant material that foams or swells up in the event of a fire, as well as an attack-resistant layer having a transparent plastic that is solid at room temperature. The flame-retardant composite glass has, between the first glass panes, an edge compound extending along and around the edges such that a chamber filled with said flame-retardant material is defined by the first glass panes and the edge compound. Between at least one of the first glass panes and the flame-retardant material, a primer layer is arranged that includes a material whose adhesion to the flame-retardant intermediate layer and/or to the glass pane becomes weaker in flame-retardant test conditions than it is in room temperature conditions.Type: GrantFiled: December 19, 2013Date of Patent: January 22, 2019Assignee: SAINT-GOBAIN GLASS FRANCEInventors: Norbert Schwankhaus, Ulrich Hermens, Udo Gelderie

Publication number: 20170274628Abstract: A light-permeable heat protection element having a first and a second support member and having an intermediate layer between the first and the second support member. The intermediate layer has a cured alkali silicate gel formed of an aqueous alkali silicate solution and a silicon dioxide compound. The alkali silicate gel of the intermediate layer thereby has a molar ratio of silicon dioxide (SiO2 to alkali metal oxide (M2O) greater than 4. Furthermore, the alkali silicate gel has 0.05 to 0.14 weight percent of lithium silicate.Type: ApplicationFiled: November 24, 2015Publication date: September 28, 2017Inventors: Udo Gelderie, Norbert Schwankhaus, David Te Strake

Publication number: 20130196091Abstract: A fire-resistant glass unit is provided having at least two transparent carrier elements, in particular glass panes, and an intermediate layer between the carrier elements, this layer expanding for example in the event of a fire, or a gas-releasing intermediate layer, which builds up a pressure between the carrier elements. At least one glass pane of the fire-resistant glass unit, preferably the two outermost glass panes, or even all the glass panes adjacent to an intermediate layer, are provided with specific local weakening as a defined breaking point. A predetermined breaking point may be, for example, a groove or milled recess, in particular a notch.Type: ApplicationFiled: June 28, 2011Publication date: August 1, 2013Applicant: VETROTECH SAINT-GOBAIN (INTERNATIONAL) AGInventors: Klaus Wildenhain, Udo Gelderie, Norbert Schwankhaus
