Solid Concrete - a wall construction category used with masonry, precast, and poured-in-place solid concrete, and solid concrete masonry units. There are ten wall thicknesses from which to choose.
Concrete Block - concrete masonry units
Solid Grouted - concrete masonry units with the cell completely filled with concrete.
Partially Grouted, Cells Empty - concrete masonry units with at least 50% of the cells free of grout or cells that are grouted no more than 32" o.c. vertically and 48" o.c. horizontally.
Partially Grouted, Cells Insulated - concrete masonry units with at least 50% of the cells free of grout or cells that are grouted no more than 32" o.c. vertically and 48" o.c. horizontally with integral insulation (e.g., perlite or rigid insulation inserts within the cells of the concrete block).
Unreinforced, Cells Empty - concrete masonry units with no metal/steel reinforcing rod within the concrete block construction, concrete cells are at least 50% free of grout or cells that are grouted no more than 32" o.c. vertically and 48" o.c. horizontally.
Unreinforced, Cells Insulated - concrete masonry units with no metal/steel reinforcing rod within the concrete block construction with integral insulation (e.g., perlite or rigid insulation inserts within the cells of the concrete block).
Other - wall assemblies that do not fit in any of the other above-grade wall categories. You may also use the Other category if specific features of your wall give it a significantly lower U-factor than the corresponding generic wall type listed in the menu. See Assembly U-Factor under Exterior and Interior Wall Software Inputs.
