Knock-Down ICF "Plank" form can be used for single story or multi-story residential or commercial projects. EPS Planks and plastic Spacer Ties are normally assembled at jobsite. Allows for assembly 'through' pre-placed rebar. Flat, monolithic cavity will accommodate all rebar requirements. Pre-molded corner and exclusive accessories make assembly, set-up and bracing fast and easy. High density packaging reduces shipping and handling costs up to 50% (when compared to pre-assembled ICF systems). Hardware packages are available to build virtually any wall shape.
