An insulation product is provided comprising an insulation sheet containing randomly oriented fibers bonded together. The sheet has first and second major surfaces and a pair of side portions. A nonwoven facing layer is bonded to at least one of the major surfaces. The nonwoven facing layer comprises randomly oriented bicomponent fibers, each of the bicomponent fibers including first component and second component portions. The nonwoven facing layer is bonded to the at least one major surface at least in part by a meltbond between the first component portion of the bicomponent fibers and the randomly oriented fibers in the insulation sheet.

A baffled insulation product for ventilating air under a roof from an open space is provided comprising an elongated insulation mat having top and bottom major surfaces, the top major surface facing the roof when the product is installed in the open space, the insulation mat having a baffle integral therewith proximate to the top major surface, comprising at least one airflow channel for the ventilating air.

Insulation batt having integral baffle vent

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%.

The present invention relates to a method for improving the thermal performance of fibrous glass insulation in the admix recycling of the insulation, which includes the use of corrugated hose in the recycling process.

The present invention relates to a method of making a board product with fiber scrap materials, including the steps of adding a binder powder to the fiber scrap materials, processing the scrap fiber into pieces and mixing the fiber scrap materials with the binder powder, distributing the fiber and binder combination across the width of a forming conveyor, and melting the combination to fix the fiber with the binder.

Process for making a board product from scrap materials

Dispensing equipment for dispensing blown loose-fill insulation. The equipment includes a flexible delivery conduit that conveys loose-fill insulation material from a source of such material and, possibly, an optional a rigid tubular wand connected to the distal end of the conduit. The equipment further includes an insert projecting radially inwardly into the loose-fill insulation flow path of the delivery conduit and/or wand for mechanically separating the insulation material's fibers and particles prior to discharge from the delivery conduit or wand. The insulation material separating structure conditions or &ldquo;opens&rdquo; the insulation material in such a way that the material is discharged in a substantially uniform density stream of substantially uniformly distributed fibers and particles.

Loose-fill insulation dispensing apparatus including mesh conduit liner

A wheeled system and a method for installing insulation from bound insulation bales. At least one movable wall that continually moves unbound insulation bales by a drive means toward a dispensing end of the base where shredding of the insulation from the unbound insulation bales occurs. The shredding is accomplished by a plurality of picker drums. Each of the picker drums has positioned on the circumference a plurality of abraders in the form of scoops that abrade and remove clumps of insulation from the unbound bales permitting the clumps to fall into a blender wherein the insulation material is formed into particulate material and then cast into an air blower formed with the hose and nozzle for dispensing the blowing material. A force measurer including a strain gauge is operatively connected to the shredder to determine continuously changes in the horizontally directed force exerted by the insulation bales against the drums of the shredder in order to adjust the force. The system can also include an electronic member for determining and monitoring the amount of insulation material dispensed and for automatically controlling the dispensing of insulation by the system.
