Method for forming a flexible, thermal-barrier sheet product, and associated apparatus

A flexible fire-resistant and thermal resistant sheet, said sheet comprising:

• a first sheet product layered with and secured to a co-extending second sheet product, each sheet product comprising an insulation material sheet layered with a co-extending cover sheet, the insulation material and cover sheets each having a perimeter corresponding to a perimeter of the respective sheet product, the insulation material sheet being comprised of filiform glass fibers and being layered with the co-extending cover sheet, the insulation material sheet and the cover sheet being secured together with a first stitching material arranged to form lateral stitching and extending only between the insulation material sheet and the cover sheet of each of the first and second sheet products, the layered and co-extending first and second sheet products being arranged such that the perimeters thereof are coincident and such that the insulation material sheet of the first sheet product is disposed directly adjacent to the insulation material sheet of the second sheet product, with the layered and co-extending first and second sheet products being secured together about the coincident perimeters thereof with a second stitching material arranged to form a plurality of separate and individual point stitches extending between the respective cover sheets, and such that the layered and secured together sheet products cooperate to form the flexible fire-resistant and thermal resistant sheet,
• wherein one of the first and second insulation material sheets and the first and second cover sheets, and one of the first and second stitching materials is interacted with a fire-retarding solution including one or more of a boron compound, a phosphorus compound, a chlorine compound, a fluorine compound, an antimony compound, a borate compound, a halogen compound, boric acid, an inorganic hydrate, a bromine compound, aluminum hydroxide, magnesium hydroxide, hydromagnesite, antimony trioxide, a phosphonium salt, ammonium phosphate, diammonium phosphate, methyl bromide, methyl iodide, bromochlorodifluoromethane, dibromotetrafluoroethane, dibromodifluoromethane, carbon tetrachloride, urea-potassium bicarbonate, and combinations thereof.
