RE: Castle Block Products

[john the architect]

The word is cementitious. Does anyone out there use spell check? Anything made of cement, from plaster, to prefab panels (the exterior parts of Protec), to Rastra/Castelblock (relatively heavy fireproof ICF using encapsulated lightweight insulating foam as the aggregate). Protec would be a lightweight wall that could be part of a raised foundation system. Any ICF system would be impractical to float in the air unless it was engineered with arches and other
trick structural approaches.
