Cementitious siding having encapsulated foam core

摘要

A molded siding member (12, 12a) having an encapsulated foam core (20) that extends substantially the entire length of the member in which it is contained, and a system (200, 300) for molding the member. The siding member includes a cementitious shell (22) molded about the foam core (20), the shell (22) being formed from cementitious slurry, including gypsum cement and a latex/water mixture, or hydraulic cement. After sufficient curing, the siding member (12, 12a) is removed from the mold system (200, 300) and is ready for immediate use and/or further processing. Alternatively, a continuous method is also provided for producing relatively long lengths of the siding product that can be cut to an appropriate size, without the need to produce individual siding members of limited size.
