Abstract: 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.

Abstract: A method is provided to produce fine diameter glass fibers with fewer defects through a combination of lower attenuating gas velocities and the use of spinners having more and smaller holes. The method uses a device for internal centrifugation of mineral fibers including a centrifuge equipped with a peripheral band perforated with orifices distributed in a plurality of annular zones arranged on top of each other, assuming that the centrifuge is in centrifugation position. The device includes at least two annular zones whose number of orifices per unit of surface area differs by a value greater than or equal to 5%, 10%, or 20%.

Abstract: An insulation product contains a layer of textile, rotary and/or flame attenuated fibers. A process for manufacturing the insulation product includes passing fibrous bundles of one or more of textile fibers and of rotary and/or flame attenuated fibers together through an apparatus that separates the fibers and the mixes the separated fibers. The bundles of rotary and/or flame attenuated fibers can be in the form of specially manufactured mats and/or can be production scraps. The resulting mixture of fibers is formed into a non-woven batt, mat, blanket, or board. The process provides homogeneous fiber product with an improved appearance. The textile fibers can enhance thickness recovery of compressed product. Blends of textile glass fiber with rotary and/or flame attenuated glass fiber exhibit an improved combination of thermal and acoustic insulating performance and adequate strength, at a low production cost.

Abstract: Glass fiber insulation products, and methods of manufacturing small diameter glass fibers with fewer stress-rising defects. The insulation products can provide the same thermal resistance or R-value with reductions in fiber density of at least about 20% or more while achieving acceptable recovery of the nominal thickness following compression.

A preferred method uses a device for internal centrifugation of mineral fibers including a centrifuge equipped with a peripheral bland perforated with orifices distributed in a plurality of annular zones arranged on top of each other, assuming that the centrifuge is in centrifugation position.
