A fibrous insulation product having a plurality of randomly oriented glass fibers and a binder composition that holds the glass fibers together is disclosed. The fibrous insulation product has an R-value in the range of 10 to 54 and, after curing, has a density, when uncompressed, in the range of 0.30 pcf to 2.7 pcf. Furthermore, the fibrous insulation product includes glass fibers that, prior to the application of the binder composition, have an average fiber diameter in the range of 15 HT to 19 HT and a quantity of binder that is in the range of 2% to 10% by weight of the fibrous insulation product. The fibrous insulation product also has an average fiber diameter to density ratio (Fd/D) of less than or equal to 40 and a comfort factor less than or equal to 3.417(Fd/D)+60.

Fiberglass insulation product

A fibrous insulation product comprising a plurality of randomly oriented glass fibers and a cross-linked formaldehyde-free binder composition at least partially coating the fibers is disclosed. The cross-linked formaldehyde-free binder composition is formed from an aqueous binder composition comprising 5.0% by weight to 37.0% by weight of at least one monomeric polyol having at least four hydroxyl groups and at least 50.0% by weight of a cross-linking agent comprising a polymeric polycarboxylic acid having at least two carboxylic acid groups, based on the total solids content of the aqueous binder composition. The glass fibers have an average fiber diameter in the range of 8 HT to 12 HT. The fibrous insulation product, after curing, has a density, when uncompressed, in the range of 0.30 pcf to 2.7 pcf.

A loose-fill insulation product having irregularly shaped glass fibers is provided. The loose-fill insulation product shows improved recovery, lower thermal conductivity and requires lower product densities than prior art loose-fill insulation at equivalent fiber diameters.

Loose-fill insulation having irregularly shaped fibers

A fiber insulation product comprising hollow fibers. Each hollow fiber may be composed of at least two different thermoplastic insulating materials, such as glasses, having differing coefficients of thermal expansion, with each of the hollow fibers being an irregular-shape exhibiting a substantially uniform volume filling nature, and providing improved recovery and thermal conductivity abilities even in the absence of a binder material. An apparatus for making hollow fibers for such a product is also provided.

Hollow multi-component insulation fibers and the manufacturing of same

A method of making an insulation product of hollow fibers whereby molten insulation material is centrifuged through a plurality of orifices and gas is directed into the molten insulation material through a plurality of gas conduits, wherein each gas conduit directs gas into one of the portions of the molten insulation material being centrifuged through one of the orifices to form a hollow fiber having a hollow bore formed therethrough. The hollow fibers are combined to form the insulation product.

A glass fiber insulation product includes irregularly-shaped glass fibers of two different glasses having differing coefficients of thermal expansion, with the irregularly-shaped dual-glass fibers exhibiting a substantially uniform volume filling nature, and providing improved recovery and thermal conductivity abilities even in the absence of a binder material.

Dual-glass fiber insulation product

A loose-fill insulation product is provided which may be poured or blown by a consumer. The insulation is comprised of irregularly-shaped glass fibers which are comprised of two distinct glass compositions. The loose-fill insulation product may be densely packaged in a small container for consumer use, and shows improved recovery, good thermal efficiency, and low dust upon blowing or pouring.

Glass fiber insulation product

Apparatus for making hollow multi-component insulation fibers

A loose-fill insulation product is provided which is formed from a blend of first and second insulating materials having three-dimensional groups of fibers of different sizes and densities. At least one of the insulating materials is comprised of irregularly-shaped glass fibers comprised of two distinct glass compositions. When blended with the fibers of a standard insulation or with other irregularly-shaped fibers of different sizes, the resulting loose-fill insulation product shows improved coverage and thermal efficiency.

Blended loose-fill insulation having irregularly-shaped fibers

Apparatus for making dual component fibers is provided and includes a spinner having a peripheral wall. The spinner includes orifices located on the peripheral wall thereof for centrifuging the dual component fibers, with the spinner being divided into a series of generally vertically-aligned compartments by baffles positioned circumferentially around the interior of the peripheral wall. First and second molten thermoplastic materials are supplied to the spinner and directed into alternate ones of the compartments so that adjacent compartments contain different thermoplastic materials. Passages are located in each of the compartments through which the respective molten thermoplastic materials flow to the orifices on the peripheral wall of the spinner. The passages in adjacent ones of the compartments communicate with one another and with the orifices to join the first and second molten thermoplastic materials together into dual component fibers.

Spinner for manufacturing dual-component fibers

Apparatus for making dual component fibers is provided and includes a spinner having a peripheral wall. The spinner includes orifices located on the exterior of the peripheral wall for centrifuging dual component fibers, with the spinner being divided into at least two compartments. The first and second molten thermoplastic materials are supplied to the spinner and directed into alternate ones of the compartments so that adjacent compartments contain different thermoplastic materials. Passages are located in each of the compartments through which the molten thermoplastic materials flow to the orifices on the peripheral wall of the spinner. At least some of the passages have branches which form a common inlet adjacent to the interior of the peripheral wall and which communicate with at least two different orifices on the peripheral wall of the spinner.

Spinner for dual component fibers having multiple exits for each inlet

A glass fiber insulation product comprises irregularly-shaped glass fibers of two different glasses having differing coefficients of thermal expansion, with the irregularly-shaped dual-glass fibers exhibiting a substantially uniform volume filling nature, and providing improved recovery and thermal conductivity abilities even in the absence of a binder material.
