Abstract
A method for forming an insulation product based on a composite of mineral wool and another first material comprising the steps of: (1) forming mineral wool fibers using at least one fiberizing device; (2) introducing the first material to the formed mineral wool fibers at a location proximate the fiberizing device to form a first mixture; (3) drawing the first mixture into a collector to form a structure having a predetermined thickness; and (4) subsequently processing the first mixture to form the insulation product, wherein the first material is disposed throughout the insulation product.

A method for forming an insulation mat product based on a composite of mineral wool and a first material comprising the steps of:
- forming mineral wool fibers using at least one fiberizing device;
- processing the first material to form nodules of the first material of a first preselected size;
- metering and weighing the nodules of the first preselected size;
- subsequent to metering and weighing the nodules of the first preselected size, processing the nodules of the first preselected size to form nodules of a second preselected size, the second preselected size being different than the first preselected size;
- introducing the nodules of the second preselected size to the formed mineral wool fibers at a location proximate the fiberizing device to form a first mixture, wherein the nodules of the second preselected size are introduced to the formed mineral wool fibers so that the insulation mat product includes between about 10% and 40% by weight of the nodules of the second preselected size;
- drawing the first mixture into a collector to form a structure having a predetermined thickness;
- and
- subsequently processing the first mixture to form the insulation mat product, wherein the nodules of the second preselected size are disposed throughout the insulation product;
- wherein the mineral wool fibers and the nodules of the second preselected size are in a dry form when combined to form the first mixture.

- processing the first material to form nodules of the first material of a first preselected size;
- metering and weighing the nodules of the first preselected size;
- subsequent to metering and weighing the nodules of the first preselected size, reducing a size of the nodules of the first preselected size to a second preselected size, the second preselected size being different than the first preselected size;
- introducing the nodules of the second preselected size to the formed mineral wool fibers at a location proximate the fiberizing device to form a first mixture, wherein the nodules of the second preselected size are introduced to the formed mineral wool fibers so that the insulation mat product includes between about 20% and 30% by weight of the nodules of the second preselected size;
