The Castleblock™ Forming Systems
Castleblock™ is a lightweight and insulated stay-in-place concrete form, made from expanded polystyrene (or foamed polystyrene), which is a common plastic. Expanded polystyrene is widely used in the building industry as insulating material and is noted for its safe properties for installers and consumers and the durability of its high insulating quality.
There are two styles of Castleblock™ forms, the Standard Form or SF-10 and the Variable Form or 12VWF. Both products have unique characteristics. This allows one to choose those features that best fit the desired performance. Both forms have rows of interlocking teeth at the top and bottom to facilitate easy assembly. The form units remain after placing of reinforcing steel and concrete and must be protected by approved interior and exterior finish materials.
Castleblock™ 12VWF (for 12 inches high variable width form) is a flat block that arrives disassembled for easy shipping and storage. . This form is very similar to a conventional form with snap ties. The form creates a flat, solid wall of concrete with nominal widths. The face shells have slots along one side. Eight rigid plastic ties slide into the slots of two face shells to create the assembled block. The face shells measure 12 inches high by 40 inches long. They are 2.125 inches tick and made from expanded polystyrene. Their upper and lower edges have teeth for interconnecting adjacent blocks. The ties come in various lengths to create thickness of 3.75, 5,75, 7.75, 9.75, 11.75 and larger custom-made thickness. EPS end pieces are also available to close off the end of the block so it can be used as a corner.
Castleblock™ SF10 (for 10 inches high standard form) is a one piece, all foam, and screen grid block. It measure 10 inches high by 40 inches long and comes in one thickness to create a concrete thickness of 6.5 inches. This form creates a structural grid of solid reinforced concrete columns and beams 10”” on center horizontally and vertically. The face shells have a minimum thickness of 1.75 inches. Their upper and lower edges have teeth for interconnecting adjacent blocks. EPS end pieces are also available to close off the end of the block so it can be used as a corner. The grid pattern permits desired flexibility in high seismic areas. It also facilitates use of more rebar and less concrete to equate the structural strength of a typical 8”” solid concrete wall.
Castleblock™ replaces conventional concrete formwork or masonry block in residential and light commercial applications. Castleblock™ forms are left in place after concrete is poured and provide superior insulation relative to conventional wood, concrete and masonry walls
