  • Publication number: 20220112637
    Abstract: A hybrid reinforcing fabric includes glass fibers and carbon fibers. The hybrid reinforcing fabric can be readily infused at an acceptable infusion speed, without requiring that the carbon fiber tows used to form the hybrid reinforcement fabric be spread or pre-impregnated with resin. Thus, the fabric provides for an effective one-step (i.e., in the mold) infusion process during composite part formation.

  • Publication number: 20190330437
    Abstract: A polymer foam is provided. The polymer foam is formed from a composition that includes a polymer, 2% to 10% by weight nano-crystalline cellulose based on the total weight of the polymer foam, and at least one blowing agent. The polymer foam exhibits a reduced thermal conductivity (k-value) and a higher water vapor permeability as compared to an otherwise identical polymer foam without nano-crystalline cellulose.

  • Patent number: 9334651
    Abstract: Roof systems and related method having a roof deck, a plurality of shingles, and a plurality of fasteners, having a material that partially changes state and displaces into the roof deck material to secure the fasteners and shingles to the roof deck. The shingles can be positioned in an overlapping pattern, and the fasteners can have first portions configured to penetrate into the roof deck and can have at least one material that melts at a threshold temperature. The first portions of the fasteners extend through one or more shingles and penetrate into the roof deck, where the material of the first portion of the fasteners increases in temperature above the threshold temperature, partially changing into a more flowable state, and displaces into voids in the material of the roof deck. Second portions of the fasteners engage the upper surfaces of the shingles to secure the shingles to the roof deck.

  • Publication number: 20130291990
    Abstract: A duct insulation laminate an insulation layer and a facing. The insulation layer includes an insulation layer having a first edge surface, a second edge surface that is spaced apart from the first edge surface, a first face surface that extends from the first edge surface to the second edge surface, and a second face surface that is opposed to and spaced apart from the first face surface. The second face surface extends from the first edge surface to the second edge surface. The facing is attached to the first face surface, and includes a polyester blended non-woven veil defining an outermost exterior surface of the duct insulation laminate.

  • Patent number: 8557366
    Abstract: A roofing shingle includes a buttlap portion with a butt edge and a headlap portion with a head edge. The roofing shingle includes a coated mat which is a roofing mat coated with an organic-based coating material. The roofing shingle also includes a water impermeable sheet adjacent to the coated mat. In one embodiment, the headlap portion of the coated mat is mostly replaced by the sheet. In another embodiment, the roofing shingle has a limited width. In a further embodiment, the roofing shingle is reduced in weight compared to a conventional shingle.

  • Patent number: 7827753
    Abstract: A roofing shingle comprising a mat having regions of various thicknesses. A layer of asphalt-based material coats the mat and a layer of granules is deposited on the asphalt-coated mat. The variations in the thickness of the regions of the mat give the shingle differences in thickness corresponding to the thickness variations in the regions of the mat, thereby giving the shingle an appearance of depth.
