Abstract
An insulative and lightweight fire barrier composition contains foam or lightweight aggregate and calcium sulfoaluminate cement or their blend with Portland cement or gypsum hemihydrate. The blocks, coatings, and panels made with such compositions are as non-combustible as fiberglass, mineral, and rock wool insulation, yet possess the dimensional stability and rigidity for manufacturing into blocks and panels with good handling and installation features that these fibrous counterparts are lacking. The fire barrier properties of this composition are comparable with or better than cellular glass, cement, gypsum, and intumescent coatings.
Claims19
An insulative and fire-resistant composition, the composition comprising:
- foamed or lightweight composites containing calcium sulfoaluminate or a calcium sulfoaluminate blend with cement or gypsum,
- wherein the composition is capable of being precast or cast-in-place and capable of being used as fire protective coatings, panels, or blocks over wood, metal, plastic and plaster substrates and used as fire resistant exterior cladding of residential, commercial, and industrial buildings.
