摘要:
A method of reducing the amount of cooling energy required to heat and cool a building is provided. The method includes disposing a porous insulating material in the exterior walls and substantially covering the ceiling in the attic space of the building to a substantial depth. The porous insulating material includes a desiccant. The method further includes permitting the desiccant—bearing porous insulating material to adsorb water moisture from the attic space and then permitting the adsorbed water moisture to desorb from the desiccant—bearing porous insulating material into the enclosed room of the building, resulting in a reduction in the amount of energy required to heat and cool the building.
摘要:
A fibrous insulation has insulation fibers (104) with a fungicide in a dispersed additive affixed to the fibers (104), and a method of making a fibrous insulation by dispersing a fungicide and a dispersed additive on the fibers (104) followed by affixing the dispersed additive on the fibers (104). The method produces thermal, acoustic, duct liner or board insulation either as loose fill insulation or as an insulation mat.
摘要:
A wheeled system and method for installing insulation from bound insulation bales. At least one movable wall (52) that continually moves unbound insulation bales (B) by a drive means (66, 68) toward a dispensing end (32) of the base (24) where shredding of the insulation from the unbound insulation bales (B) occurs. The shredding is accomplished by a plurality of picker drums (78). Each of the picker drums (78) has positioned on the circumference a plurality of abraders (88) that abrade and remove clumps of insulation from the unbound bales permitting the clumps to fall into a blender (98a, 98b, 98c) wherein the insulation material is formed into particulate material and then cast into an air blower (110). A force measurer (120) including a strain gauge is operatively connected to the shredder.

A system for blowing loose-fill insulation includes a loose-fill blowing machine (12) including a discharge hose (14). An ionizer (16) is disposed in the flow path of the insulation through the discharge hose (14), wherein the ionizer (16) reduces the static charge developed on the insulation prior to discharge thereof. A method for reducing static charge developed on loose-fill insulation during blowing is also provided and includes the step of ionizing the insulation in the flow path of the insulation while the insulation is being discharged to reduce the static charge.
摘要:
A lightweight, high-strength composite fabric (110) suitable for use in a carpet backing, roofing and membranes and other products which employ rugged fabrics. The composite fabric (110) comprises a layer of nonwoven material (116) disposed between a layer of low shrinkage warp strands (112) and a layer of low shrinkage weft strands (114). The layers are stitched or knitted together and the resultant fabric (110) may be coated with a resin or sizing agent (122) to prevent slippage between the several layers of the fabric (110) and impart a measure of stiffness to the fabric (110). The fabric may be manufactured in sheet or, more preferably, roll form and may be coated with materials suitable for desired end applications, e.g., bituminous material whereby the fabric (110) may function as a ready-to-use roofing membrane or other high-strength fabric product.
摘要:
Encapsulated glass fiber insulation is made by forming an encapsulating or covering material (152) over the top surface of a glass fiber mat or core (11) with the formed covering material extending adjacent the side surfaces. The covering material is greater in width than the sum of the widths of the top and two side surfaces, so that the edges of the formed covering material extend beyond the mineral fiber core. A vacuum is applied below the mineral fiber core via vacuum duct (186) to draw the formed covering material extending beyond the side surfaces under the core.
摘要:
Certain embodiments described herein are directed articles that include a cellulosic substrate (or a non-cellulosic substrate) and an aqueous dispersion disposed on the substrate. In certain examples, the dispersion is effective to provide a water vapor perm rating of about 2 perms or less at 25% average RH as tested by ASTM D1653, or about 2 perm or less at 25% average RH as tested by ASTM E96, when the dispersion is cured as a coating on the substrate. In some embodiments, the substrate can be (or can be part of) a building substrate such as, for example, kraft paper placed on insulation (e.g., fiberglass insulation) or oriented strand board. In some instances, the aqueous dispersion can include a plant oil macromonomer or a waterborne epoxy resin.

A coating dispersion or building article can include titanium dioxide, and a dihydrazide. The coating dispersion or building article can further include calcium carbonate, calcined aluminum silicate, acrylic polymers, and a fluoroalkyl polymer.
摘要:
A method of making a lapped fibrous insulation is provided which includes the steps of conveying a cured binder-impregnated mat of fibers, the mat having a thickness, a longitudinal length and transverse ends. The method further includes providing a plurality of spaced, perhaps every 24 inches to 120 inches, transverse cuts through at least a portion of the thickness of the mat, and lapping the mat of fibers in opposite directions to fold said mat into a generally sinous configuration, having a series of continuous lengths wherein at least one of the transverse cuts is aligned with at least one of the folded regions for assisting in making the mat of fibers easier to fold during the lapping step. A fibrous insulation material in the form of a lapped roll in accordance with this invention is also provided.
