Abstract: There is provided a premanufactured structural building panel system for effectively promoting the efficient construction of the exterior wall members of a building having improved insulation, sound absorption, fire retardant and structural properties. The premanufactured structural building panels are made of a pair of C-shaped structural channels having first and second flanges. The channels are secured to a foam insulation member to form the panels. A fire retarding member can be secured to a flange of at least one of the channels to define an interior surface. The structural panels are supported on wall support members and connected to each other in a side-by-side fashion to form an exterior wall member of a building. The exterior wall members include vertical sidewalls, a horizontal roof and ceiling wall, and a pitched roof system. The interior surface of the walls can be prepared for finishing. Affixed to the exterior of the wall members is a weatherable covering.

Abstract: There is provided a premanufactured structural building panel system for effectively promoting the efficient construction of the exterior wall members of a building having improved insulation, sound absorption, fire retardant and structural properties. The premanufactured structural building panels are made of a pair of C-shaped structural channels. The panels include a fire retarding board secured to opposing angle members and a foam insulation member secured to the fire retarding board. A plurality of retaining members may be provided for additional structural support. The structural panels are supported on wall support members and connected to each other in a side-by-side fashion to form an exterior wall member of a building. The panels are arranged such that the C-shaped channels are protected from conditions external to the building by a portion of the foam insulation members. The exterior wall members include vertical sidewalls, a horizontal roof and ceiling wall, and a pitched roof system.

Abstract: There is provided a self-supporting insulated deck structure for buildings whereby the deck can be constructed inexpensively and efficiently and can attain a desirable fire rating in addition to improved sound absorption properties. The self-supporting insulated deck structure is made of a cementitious material and has no exposed structural steel members. Formwork for the insulated deck structure is made of integral panels formed from foam insulation members, fire retarding boards, and sound attenuating boards. The integral panels are supported on shored steel support brackets. Once the cementitious material cures, the shoring is removed as the deck structure is self-supporting. The adjacent integral panels provide the insulated deck structure with desirable fire rating and sound absorption properties.
