Patent number: 11787741Abstract: An acoustical geopolymer panel element includes a layer including a fibre component and a geopolymer binder made from a mixture including ground mineral wool, and an additional layer including mineral wool. The layer including a fibre component and a geopolymer binder has a density in the range of 20-400 kg/m3, a porosity in the range of 0.75-0.99 and a thickness in the range of 5-75 mm. The ground mineral wool may be ground glass or stone wool and the fibre component may be a wood fibre component, a polymer fibre component and/or a mineral wool component. Further, a geopolymer mixture is provided upon recycling mineral wool which is ground to powder and mixed with an alkali activator component. Additionally, a method for producing acoustical geopolymer panel elements includes grinding elements including mineral wool for provision of a powder component.Type: GrantFiled: August 28, 2019Date of Patent: October 17, 2023Assignee: SAINT-GOBAIN ECOPHON ABInventors: Ola Karlsson, Torbjorn Persson
