| 20120108135 | METHOD OF MAKING A REINFORCING MAT FOR A PULTRUDED PART - A method of preparing a reinforcing structure for use in manufacture a pultruded part where the reinforcing structure is pulled through a pultrusion die in a continuous longitudinal pull direction. The method includes arranging a plurality of first reinforcing fibers in a transverse direction and attaching a permeable transport web of staple fibers to the first reinforcing fibers such that the portion of the first reinforcing fibers oriented in the direction transverse comprises at least 30% of a volume of materials comprising the reinforcing structure. | 05-03-2012 |
| 20120102872 | SELF-SEALING WINDOW AND INSTALLATION METHOD - A self-sealing window with a flexible gasket that extends around the entire perimeter of closure assemblies and a method of installing such closure assemblies in a rough opening. A sealing member is attached continuously around an entire perimeter of the closure assembly to form a water impermeable seal between the sealing member and the closure assembly. The closure assembly is inserted into the rough opening. Accurate positioning of the closure assembly in the rough opening is verified. The closure assembly is secured in the rough opening. The sealing member is engaged with an exterior surface of the structure proximate the rough opening. A foam material is delivered into at least a portion of a space between perimeter edge surfaces of the closure assembly and inner surfaces of the rough opening. | 05-03-2012 |
| 20110239562 | FENESTRATION UNIT WATER RESTRICTOR AND METHOD - A water restrictor adapted to control water diversion from one or more channels in a lower member of a fenestration unit, such as a prehung sliding door or window. | 10-06-2011 |
| 20110061319 | IG UNIT MEMBRANE VALVE AND PRESSURE MODIFICAITON - An IG unit includes a perimeter structure having a port, a first pane supported by the perimeter structure, a second pane supported by the perimeter structure opposite the first pane with an interior space defined between the first and second panes that is sealed and connected to the port, and a membrane valve assembly adapted to act as a self-sealing access to the port. The membrane valve assembly optionally includes a first sealant layer, a second membrane layer, and a third sealant layer, for example. | 03-17-2011 |
| 20110047884 | WEATHER SEAL SYSTEM - Some aspects relate to weather seal systems for forming water barriers and air barriers. Some air barriers include a sill portion, a frame portion, and a transition portion extending between the sill and frame portions, where the transition portion extends inwardly and downwardly from the frame portion of the air barrier, toward an interior side of an associated door assembly, to the sill portion of the air barrier. The transition portion optionally provides a buffer zone, or transition zone of air at a greater spacing from the water barrier. In some embodiments, the transition zone is equilibrated to external pressures and supplies substantially dry air to air leaks in the air barrier. | 03-03-2011 |
| 20100229468 | RETRACTABLE SCREEN SYSTEM PROVIDING A POSITIONING FORCE FOR A MOVABLE SASH - A door with a moveable window sash and a method of operating the same. The door includes vertical jambs with vertical channels. A window sash is movable in the vertical channels. A retractable screen assembly is attached to the door. The retractable screen assembly includes a roller, a flexible screen attached at a first end to the roller and at a second end to the movable window sash, and a biasing mechanism adapted to apply a continuous torque to the roller. The torque generates a positioning force on the window sash equal to at least 50% of the force of gravity acting on a window sash, such that the window sash can be positioned at an infinite number of locations along the vertical channels. | 09-16-2010 |
