Appl. No.:

12/758910

Inventors:

David R. Mirth - Reynoldsburg OH, US
William M. Babbitt - New Albany OH, US
Liang Chen - New Albany OH, US
Jesus M. Hernandez-Torres - Pataskala OH, US

International Classification:

D04H 1/64

C03B 37/01
C03B 37/10
C03C 25/42
E04B 1/74

US Classification:

4282974, 4282921, 65442, 252 62

Abstract:

A rotary fibrous insulation product that is soft to the touch is provided. The fibrous insulation product is formed of glass fibers having an average fiber diameter less than about 5.5 microns. The low fiber diameter helps to impart a soft feel to the insulation product. Additionally, the insulation product contains an oil with a flashpoint of at least 580 F. in an amount up to 5% by weight of the insulation product. The insulation product may contain up to about 85% by weight recycled glass. In exemplary embodiments, the binder is a low-formaldehyde, polyacrylic based binder. The combination of the low fiber diameter, the binder, and the oil create a synergistic effect to produce an unexpectedly soft insulation product. The insulation product is useful in a variety of thermal applications, such as in basements, in attics, and in walls of residential dwellings.

US Classification:

65377, 65484

Abstract:

Apparatus, systems and methods for monitoring and controlling the amount of moisture introduced into the forming hood area in the manufacture of mineral fiber insulation products. Moisture from coolant liquids, binder dispersions and binder diluents are all introduced deliberately into a forming hood; ambient moisture and water from combustion are additional sources. A series of global variable control valves, one for each fluid system; as well as individual variable control valves for each fiberizing unit are provided with associated meters. Sensors monitor fibrous pack conditions and ambient conditions and provide inputs to the valve control system. A specific 3-ring liquid dispensing system is also disclosed.

Appl. No.:

13/234336

Inventors:

Timothy Turner - Mansfield TX, US
Ann Marie dePaauw - Pickerington OH, US
Michael Ugorek - New Albany OH, US
David R. Mirth - Reynoldsburg OH, US

Assignee:

Owens Corning Intellectual Capital, LLC - Toledo OH

International Classification:

B65B 5/04

US Classification:

53428, 53473

Abstract:

Fibrous insulation products have a binder composition that may include a carbohydrate and a crosslinking agent, and potentially other optional ingredients. The shelf life and physical properties of fibrous insulation products, particularly those having bio-based binders, can be improved by packaging that completely envelopes and seals the fibrous product from exposure to atmospheric conditions. Exemplary envelopes disclosed include sealed bags, double stretch wrap and stretch hoods. Properties that can be improved include recovery of loft, restoring force and tensile strength among others.

8/905496

Inventors:

David R. Mirth - Canal Winchester OH
Irvin J. Bence - Westerville OH

Assignee:

Owens Corning Fiberglas Technology, Inc. - Summit IL

International Classification:

C03B 500

US Classification:

65495

Abstract:

A multi-screen mixing apparatus for installation in a fiber-forming bushing used in the manufacture of glass fibers. The multi-screen mixer attaches to the walls of the bushing, and includes a first screen having openings therein through which the glass flows and a second screen having openings through which the glass flows longitudinally spaced from the openings in the first screen such that the molten glass must flow in a non-linear path as it passes through the screens. Additional screens can be added to cause additional flow diversion to further mix the molten glass.
