Patent number: 6886306Abstract: The present invention provides a building material derived from straw, such as rice straw, that has significantly improved fire-resistance properties over traditional cellulose-based materials. In one embodiment, the invention provides a method of fabricating a board from milled rice straw. The milled rice straw is blended with a binder to form a mixture. The mixture is then formed into a mat with sufficient size to achieve a predetermined board thickness and density. The mat is then pressed into the board. In another embodiment, the present invention provides a fire resistant board that includes milled rice straw, a resin binder, and a fire retardant material such as an organic phosphate, zinc borate, aluminum trihydrate, sodium silicate, or even rice hulls.Type: GrantFiled: May 4, 2001Date of Patent: May 3, 2005Assignee: Greencor Composites, LLCInventors: Christopher S.

Publication number: 20040172893Abstract: A sheet metal enclosure containing a thickness of Styrofoam Insulating material designed to slide over the plywood panel on attic stairways. A rubber seal is placed on the perimeter of the back side of the panel creating a seal between the living area and attic space reducing air transfer between the two spaces. The Styrofoam provides an amount of insulation reducing temperature transfer between the two spaces. The sheet metal panel provides for the containment of the insulating material and mounting surface for the rubber seal and reduces warping of the attic stairway plywood panel because it is held rigid within the confines of the metal enclosure containing the Styrofoam. The closure springs on the attic stairway provide the tension to hold the stairway closed and create a tight seal.Type: ApplicationFiled: March 3, 2003Publication date: September 9, 2004Inventor: Michael Jim Hunter
