Building Concrete Forms
Technical Information
Our product are custom built pre-panelized stay in place forms. The forms are sequentially numbered and delivered to the site in stacks ready for installation directly on a conventional slab. During installation, the wall panels are reinforced with horizontal rebar every two feet. Finally, concrete is pumped into the cavity to create a monolithic steel-reinforced concrete structure; consequently no additional tie beams are required.
Each form is built around either a 4", 6” or 8" structural steel stud frame and then typically clad with 1/2” to 3/4" thick exterior sheathing and 2" thick extruded Polystyrene insulation held by standard 1x2 PT or metal furring strips on the interior. This composite wall imparts a thermal resistance from R-13 to R-23 using single or double insulation respectively (see Thermal Resistance Analysis Chapter for more details). Excellent sound attenuation properties, water penetration resistance, and mold resistance are some of the more important qualities of the Choice ME Special Concrete Walls.
The form system is flexible and readily accepts different combinations of cladding materials depending upon the design requirements. Standard variations create walls that are non-insulated, insulated and double insulated - typically used for interior/dividing walls.
