Abstract: Embodiments of the invention provide roofing boards and roofing systems having improved fire resistance properties and methods related to the same. According to one aspect, a roofing system is provided. The roofing system includes roofing panels positioned atop structural support members to form a roof deck. Roofing boards are positioned atop the roof deck and coupled thereto and a roofing membrane is positioned atop the roofing boards and coupled therewith. The roofing boards include a coating of a mineral based material applied to one or more surfaces in an amount between the range of about 0.10 lbs/ft2 and about 0.70 lbs/ft2. The mineral based material coating enables the roofing boards to pass the UL 790 class A tests, such as the burning brand test.

Abstract: Fiberglass products with increased flame resistance are described. The products may include fiberglass-containing thermal insulation that include a plurality of glass fibers coated with a phosphorous-containing flame retardant. The flame retardant may include an organophosphorous compound having a substituted or unsubstituted organophophorous group bonded to a substituted or unsubstituted amide group by a substituted or unsubstituted alkyl group. The fiberglass products may further include fiberglass composites that are about 50 wt. % to about 98 wt. % glass fibers, about 2 wt. % to about 50 wt. % of a binder; and a phosphorous-containing flame retardant. Also described are methods of making fiberglass products with increased flame resistance. These methods may include the steps of contacting glass fibers and/or fiberglass products with a flame retardant mixture that includes a phosphorous-containing compound.

Abstract: A composition includes glass fibers and a polyether antistatic agent. The polyether antistatic agent has a molecular weight of less than about 2000, or less than about 1000. Exemplary polyether antistatic agents include polyethylene glycol, polypropylene glycol, a glycerol polyether, and combinations thereof. The polyether antistatic agent has a viscosity of less than about 600 cSt at 75° F., or less than about 200 cSt at 75° F. The composition may further include a solvent for the polyether antistatic agent; the solvent may include one or more organic soluble electrolytes, water or a combination thereof. Exemplary organic soluble electrolytes include calcium acetate, lithium acetate, an amine acetate, sodium benzoate, and combinations thereof. The composition may be used in various insulation applications, including in an insulation batt, insulation roll, insulation board, insulation pipe or unbonded glass fiber insulation.

Abstract: According to one embodiment, a method of forming a facer includes forming a first layer of nonwoven glass fibers and positioning a second layer of reinforcement fibers atop the first layer of nonwoven glass fibers. The method also includes coating the first layer of nonwoven glass fibers and/or the second layer of reinforcement fibers with a binder composition and pressing the first layer of nonwoven glass fibers and the second layer of reinforcement fibers together between a pair of rollers. The binder composition is then dried to couple the first layer of nonwoven glass fibers and the second layer of reinforcement fibers to form the facer. The first layer of nonwoven glass fibers and/or the second layer of reinforcement fibers are free of a material coating prior to coating of the binder composition.

Abstract: According to one embodiment, a separator for a lead-acid battery includes a membrane film of an ultra-high molecular weight polymer material (UHMWPE). Precipitated silica and glass fibers are disposed throughout the membrane film and held or maintained in position by the UHMWPE.

Abstract: A burnthrough resistant non-woven mat is made of a glass fibers and includes a binder having a vinyl component and a strengthening component. The vinyl component may be, for example, ethylene vinyl chloride, and the strengthening component may be, for example, melamine formaldehyde. The burnthrough resistant non-woven mat may be used in conjunction with an insulation blanket, and may be especially suited to use in insulating aircraft. Methods of making the burnthrough resistant non-woven mat are discussed.

Abstract: Provided is a coated nonwoven mat prepared by the process of passing a nonwoven mat over the surface of a binder or coating slurry to touch the bottom side of the mat sufficiently to fully wet the glass mat. The wetted nonwoven mat is then immersed in a slurry of the binder or coating material to fully saturate the mat with the slurry material. The process of the present invention allows one to control the porosity of the saturated fibrous nonwoven mat at high consistency with reduced scrap rate. The saturated mat will have improved tensile strength.
