In one embodiment, a veil formed of glass fibers, comfort enhancing fibers, and optionally a combination of synthetic fibers is positioned on the bottom of a mattress to provide fire resistance or prevention. The binder composition used to form the veil may include a binder with a low glass transition temperature and a flame retardant additive. In a second embodiment, a glass veil is utilized in a fire retarding composite formed of an encapsulating layer, a fire retarding veil, and a backing layer. Preferably, all of the fibers in the veil are glass fibers. The fire retarding composite is positioned on the mattress with the encapsulating layer against the cushioning material, the backing layer facing externally, and the veil sandwiched between the encapsulating layer and the backing layer. A fire retarding insulation product is also provided.Type: GrantFiled: July 22, 2005Date of Patent: April 24, 2012Assignee: Owens Corning Intellectual Capital, LLCInventor: David E Weller, Jr.

Patent number: 8158539Abstract: The following disclosure provides a structural mat for manufacturing a moldable structural hardboard body. The structural mat has a nucleated/coupled binder and a fibrous material. The nucleated/coupled binder material has a first binder material combined with a nucleating agent; and a second binder material combined with a coupling agent. The first binder material is combined with the nucleating agent to make a discrete nucleated/binder material. The second binder material is combined with the coupling agent to make a discrete coupled/binder material. The discrete nucleated/binder material and the discrete coupled/binder material are blended together. The fibrous material is blended with the discrete nucleated/binder material and the discrete coupled/binder material to form the structural mat.Type: GrantFiled: December 16, 2005Date of Patent: April 17, 2012Assignee: FlexForm Technologies, LLcInventor: Garry E. Balthes

Publication number: 20120015574Abstract: A method for production of a reactive polyurethane emulsion for use in impregnating and coating a textile fabric includes reacting polyols alone or in combination with at least one of diols and triols with a substoichiometric amount of diisocyanates so as to form medium-viscosity, OH-terminated prepolymers. The prepolymers are mixed with an external emulsifier. At least one of a diisocyanate, a triisocyanate and a polyisocyanate are added so as to bring about a crosslinking of the prepolymers.Type: ApplicationFiled: March 25, 2010Publication date: January 19, 2012Applicant: CARL FREUDENBERG KGInventors: Birgit Severich, Thomas Schauber, Horst Muehlfeld, Robert Groten, Bjoern Hellbach, Ansgar Komp, Christian Waschinski

Patent number: 8097544Abstract: The present invention teaches that a tightly woven, and strong layer of fiberglass may be coated or impregnated with sodium silicate in order to produce a strong and fire resistant jamb/frame. The present invention further teaches that a fire doorjamb core may be mass produced from fire resistant layers and the frame core rated for fire safety by a rating agency, thus allowing builders and door manufacturers to produce building structures and doors using that core without individually certifying each model of door or structure. The present invention further teaches a structure/method of mounting for door frames which closely parallels mounting of normal door frames, without special brackets or plates.Type: GrantFiled: February 20, 2009Date of Patent: January 17, 2012Inventor: Kenneth Majors
