  • Patent number: 8272477
    Abstract: Novel stowed staircases for attics and the like that exhibit highly effective fireproof properties are provided. The combination of sheet metal well sides with ceramic paper covering, a combination thermal board and cement-like construction door, coupled with a sealed gasket at the interface of the stair bottom with the ceiling provide the necessary long-term fireproof capabilities as well as facilitation in installation as a sufficiently lightweight article. In such a manner, the inventive stairway construction may be easily incorporated within a residential or other type unit to aid in the simultaneous accessibility to an attic (or like location) and ability to prevent fire from easily spreading into or out of said attic via the stair assembly itself.
