Patent number: 11795684Abstract: The present disclosure relates generally to vapor retarding building materials and methods for making them. The present inventors have found simple and cost-efficient materials that have low water vapor permeability at low relative humidities and that can be provided as a coating on a building material substrate. Notably, in many embodiments, the materials can have high water vapor permeability at high relative humidities. In one embodiment, the disclosure provides vapor retarding articles comprising a building material substrate; and a polymeric coating layer coated on the building material substrate, the polymeric coating layer comprising an inorganic hydrophilic particulate filler dispersed in a continuous organic phase comprising a hydrophobic polymer, wherein the content of the filler is from about 30% to about 85% by weight of the polymeric coating layer, the vapor retarding article configured to have a water vapor permeance of no more than about 1 Perm at 25% relative humidity.Type: GrantFiled: October 5, 2021Date of Patent: October 24, 2023Assignee: CERTAINTEED LLCInventors: Timothy Jerome Coogan, Jeffrey H. Peet, Valerio Massara, Kenneth D. Knapp

Publication number: 20150176211Abstract: Certain embodiments described herein are directed articles that include a cellulosic substrate (or a non-cellulosic substrate) and an aqueous dispersion disposed on the substrate. In certain examples, the dispersion is effective to provide a water vapor perm rating of about 2 perms or less at 25% average RH as tested by ASTM D1653, or about 2 perm or less at 25% average RH as tested by ASTM E96, when the dispersion is cured as a coating on the substrate. In some embodiments, the substrate can be (or can be part of) a building substrate such as, for example, kraft paper placed on insulation (e.g., fiberglass insulation) or oriented strand board. In some instances, the aqueous dispersion can include a plant oil macromonomer or a waterborne epoxy resin.Type: ApplicationFiled: December 19, 2014Publication date: June 25, 2015Inventors: Kenneth D. Knapp, Kevin J. Gallagher, Murray S. Toas, Sam Yuan, Sharathkumar K. Mendon, James W. Rawlins

Publication number: 20110206897Abstract: A method of making a lapped fibrous insulation is provided which includes the steps of conveying a cured binder-impregnated mat of fibers, the mat having a thickness, a longitudinal length and transverse ends. The method further includes providing a plurality of spaced, perhaps every 24 inches to 120 inches, transverse cuts through at least a portion of the thickness of the mat, and lapping the mat of fibers in opposite directions to fold said mat into a generally sinous configuration, having a series of continuous lengths wherein at least one of the transverse cuts is aligned with at least one of the folded regions for assisting in making the mat of fibers easier to fold during the lapping step. A fibrous insulation material in the form of a lapped roll in accordance with this invention is also provided.Type: ApplicationFiled: February 19, 2010Publication date: August 25, 2011Inventors: KENNETH D. KNAPP, Alexander M. Rucker

Patent number: 5848509Abstract: Encapsulated glass fiber insulation includes a non-woven covering material over the top surface of a mineral fiber core, with the formed covering material extending adjacent the side surfaces. The covering material is greater in width than the sum of the widths of the top and two side surfaces, so that the edges of the formed covering material extend beyond the mineral fiber core.Type: GrantFiled: August 31, 1995Date of Patent: December 15, 1998Assignee: CertainTeed CorporationInventors: Kenneth D. Knapp, Eric S. Nilsson, Murray S. Toas

Patent number: 5685938Abstract: Encapsulated glass fiber insulation is made by forming a covering material over the top surface of a mineral fiber core, with the formed covering material extending adjacent the side surfaces. The covering material is greater in width than the sum of the widths of the top and two side surfaces, so that the edges of the formed covering material extend beyond the mineral fiber core. A vacuum is applied below the mineral fiber core to draw the formed covering material extending beyond the side surfaces under the core.Type: GrantFiled: August 31, 1995Date of Patent: November 11, 1997Assignee: CertainTeed CorporationInventors: Kenneth D. Knapp, Christopher R. Donnelly, Hal J. Robbins
