BuildLock Knockdown (KD) Forms

The BuildLock Knockdown ICF System is a high-performance knock-down insulating concrete form (ICF) wall system.

The BuildLock Knockdown Insulating Concrete Forms is a system that is comprised of two separate 2½ inch Expanded Polystyrene (EPS) panels which are connected by strong, high-density plastic webs on 6-inch centers. BuildLock is the strongest knock-down product on the market today. Each web bridge features a 3-axis positive locking attachment that snaps the web securely in the proper position to eliminate racking and provide superior structural stability throughout the construction process. The BuildLock Knockdown block exceeds even the superior strength of BuildBlock ICF blocks.
