The invention relates to curing a binder on fibrous insulation wherein, heated gas flows as a ratio of, an upward flow into the fibrous insulation, and a downward flow into the fibrous insulation, to heat the binder to its curing temperature; and the binder is cooled, thereby curing at least a portion of the binder to a thermoset state. When a remainder of the binder remains uncured, another stage of heating the binder with a ratio of heated gas followed by cooling, will cure the remainder of the binder. |
