The invention relates to a method and facility for manufacturing a fiberglass material, in which melted glass is produced in a melting furnace heated via combustion of a fuel with an oxygen-rich oxidant. The fumes generated are used to preheat a combustion reagent in two steps: a first step in which air is heated via heat exchange with the fumes, and a second step in which the combustion reagent is preheated via heat exchange with the hot air. The air is then used in the method for converting the melted glass into a fiberglass material.

An insulation pad includes a binderless pack of glass fibers and an envelope around the binderless pack of glass fibers. The glass fibers are mechanically entangled by needling such that the binderless pack has a density of from 4.5 to 5.5 pounds per cubic foot. The insulation pad is used to insulate pipes and vessels.

Fibrous insulation products have an aqueous binder composition that includes a carbohydrate and a crosslinking agent. In exemplary embodiments, the carbohydrate-based binder composition may also include a catalyst, a coupling agent, a process aid, a crosslinking density enhancer, an extender, a moisture resistant agent, a deducting oil, a colorant, a corrosion inhibitor, a surfactant, a pH adjuster, and combinations thereof. The carbohydrate may be natural in origin and derived from renewable resources. Additionally, the carbohydrate polymer may have a dextrose equivalent (DE) number from 2 to 20. In at least one exemplary embodiment, the carbohydrate is a water-soluble polysaccharide such as dextrin or maltodextrin and the crosslinking agent is citric acid. Advantageously, the carbohydrates have a low viscosity and cure at moderate temperatures. The environmentally friendly, formaldehyde-free binder may be used in the formation of insulation materials and non-woven chopped strand mats. A method of making fibrous insulation products is also provided.

The present invention relates to a method for detecting curing and/or the local distribution of curing of the binder material, in particular for detection of anomalies of the cured binder, in a mineral fiber product. The present invention also relates to a reagent, in particular for use in such a method and the use of this reagent in the quality control of bonded mineral fiber products.

The manufacture of fiberglass filtration media, and particularly paint arrestance fiberglass media, is disclosed. Fiberglass filtration media is formed in part by controlling the speed of a melter traversing a drum. The fiberglass media passes through rollers and water sprays before it enters a curing apparatus. Progressive density changes from the air intake side to the air exit side of the media result in increased filtration qualities.
