Patent number: 10000666Abstract: 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.Type: GrantFiled: June 12, 2014Date of Patent: June 19, 2018Assignee: Owens Corning Intellectual Capital, LLCInventors: Christopher M. Hawkins, Jesus Manuel Hernandez-Torres, Liang Chen, Edward Alan Martine, Jacob Chacko

Patent number: 9133571Abstract: A method of forming a needled fiberglass glass insulation product is provided. The formation of the needled insulation product may be conducted in a process in which the fibers are formed, a binder is sprayed onto the fibers, the fibers are collected and formed into a fiberglass pack, the fiberglass pack is passed through the oven, and at least partially cured insulation blanket is passed through a needling apparatus. The reduction in thickness and increased density caused by the needling process permits the production of lower thickness and high density insulation products.Type: GrantFiled: December 19, 2013Date of Patent: September 15, 2015Assignee: Owens Corning Intellectual Capital, LLCInventors: Jacob Chacko, Robert P.

Patent number: 8650913Abstract: A method of forming a needled rotary fiberglass glass insulation product is provided. The formation of the needled insulation product may be conducted in a continuous in-line process in which the fibers are rotary formed, a binder is sprayed onto the hot fibers, the fibers are collected onto a conveyor and formed into a fiberglass pack, the fiberglass pack is passed through the oven, and the cured insulation blanket is passed through a needling apparatus. The reduction in thickness and increased density caused by the needling process permits the production of lower thickness and higher density insulation products. In particular, the needled insulation product may have a thickness of less than about 0.75 inches and a density from about 1 pcf to about 10 pcf. The needled insulation product may be utilized in household appliances, water heaters, and HVAC equipment.Type: GrantFiled: November 30, 2009Date of Patent: February 18, 2014Assignee: Owens Corning Intellectual Capital, LLCInventors: Jacob Chacko, Robert P.

Publication number: 20050102971Abstract: An apparatus for determining the density of insulation in a cavity of a structure that senses a force of the insulation against the sensor. The force is used to determine the density of the insulation, which, in turn, is used to determine the thermal resistance or R-value of the insulation. The apparatus may include a fixture for supporting the sensor and holding the sensor in the substantially fixed position. A method for determining the density of loose-fill, blown-in-place insulation in a wall cavity by the use of a sensor is that measures a force exerted on the sensor by the insulation. The measured force is used to determine the density of the insulation. The thermal resistance of the insulation is determined from the known cavity depth and insulation density.Type: ApplicationFiled: October 20, 2004Publication date: May 19, 2005Inventors: Robert O'Leary, Steven Schmitt, Jacob Chacko

Publication number: 20050081604Abstract: An apparatus for determining the density of insulation in a cavity of a structure includes a sensor that is held in a substantially fixed position relative to the insulation for sensing the force of the insulation against the sensor. The force is used to determine the density of the insulation, which, in turn, is used to determine the thermal resistance or R-value of the insulation. The apparatus may include a fixture for supporting the sensor and holding the sensor in the substantially fixed position. A method for determining the density of loose-fill, blown-in-place insulation comprises the step of providing a structure with a cavity having a known depth. The cavity is covered with netting and filled with insulation. A sensor is held in a substantially fixed position relative to the insulation to measure force exerted on the sensor by the insulation. The measured force is used to determine the density of the insulation.Type: ApplicationFiled: October 21, 2003Publication date: April 21, 2005Inventors: Robert O'Leary, Steven Schmitt, Jacob Chacko
