Nudura has introduced The Optimizer, an insulated concrete form (ICF) available in four section sizes that allows designers and installers to meet 17 different stack scenarios without the need to cut or rip forms. It uses the company’s DURALOK Technology to securely lock forms into place with triple-toothed interlocks, eliminating the need to wire or glue forms. Once the forms are stacked, a continuous height-fastening strip ensures the wall becomes a single unit. Core sizes range from 6 to 12 inches.
