Abstract:
A core for a fire rated door includes a fire resistant center panel and an extruded fire resistant border. The fire resistant center panel has a bottom, a top, a first side, a second side, a first end and a second end. The fire resistant center panel is made of a first fire resistant material. The extruded fire resistant border is attached to the first side, the second side, the first end and the second end of the fire resistant center panel. The extruded fire resistant border is made of a second fire resistant material having a higher density than the first fire resistant material.

Abstract:
A high temperature lightweight thermal insulating material is formed from a mixture that includes cement or silica sand, water and a foaming agent. The foaming agent can be an aluminum powder or a surfactant. The insulating material has a maximum use temperature greater than about 600 degrees Celsius.

Abstract:
A composite product includes gypsum in an amount of 60 to 90% by weight, fibers in an amount of 1.5 to 26% by weight substantially homogeneously distributed through the composite, and a rheology-modifying agent in an amount of 0.5 to 6% by weight. The composite is caused or allowed to cure to form a cured composite. The cured composite is a fire resistant component used in a fire-rated door core, a fire-rated door or a fire-rated building panel. The fire resistant component may include a building panel, a door panel, a door core, a door rail, a door stile, a door lock block, a door border, or a door insert.
Abstract:
An expanded lightweight aggregate has compositional ranges (Wt. % Range) of about: (a) 40 to 60% ground glass or pumice, 40 to 60% water, 3 to 15% sodium silicate, and 0.1 to 5% NaNO3 for the slurry; and (b) 50 to 85% ground glass or pumice, and 15 to 50% slurry for the granulator.
