1. A method of producing a mineral wool product comprising a multiple of lamellae, said method comprising the steps of:
providing a cured mineral wool web;
cutting said mineral wool web longitudinally into a plurality of lamellae;
turning each of the plurality of lamellae 90° about their longitudinal axis;
bonding the lamellae in the turned orientation together by an adhesive on surfaces of two adjacent of the plurality of turned lamellae; and
curing the adhesive, the step of curing comprising a drying process involving blowing air or gas through the mineral wool product, the step of curing being carried out at temperatures from 5 to 95° C., wherein the adhesive comprises at least one hydrocolloid,
wherein the adhesive comprises:
proteins from vegetable sources, and the adhesive further comprises at least one phenol containing compound, wherein the at least one phenol containing compound is tannin selected from one or more components from the group consisting of tannic acid, condensed tannins (proanthocyanidins), hydrolysable tannins, gallotannins, ellagitannins, complex tannins, and tannin originating from one or more of oak, chestnut, staghorn sumac and fringe cups, and/or proteins from vegetable sources, and wherein the adhesive further comprises at least one enzyme selected from the group consisting of transglutaminase (EC 2.3.2.13), protein disulfide isomerase (EC 5.3.4.1), thiol oxidase (EC 1.8.3.2), polyphenol oxidase (EC 1.14.18.1), lysyl oxidase (EC 1.4.3.13), and peroxidase (EC 1.11.1.7);
and a density of the mineral wool product being in the range of 50-300 kg/m3.
