APEX Block™ is a revolutionary energy saving building product that provides protection against flood, fire, high winds, earthquakes and infestation. Unlike other Insulated Concrete Forms (ICFs), APEX Block™ fits together in a Keystone Interlocking System™ and eliminates the time and cost of expensive bracing and connection methods.
Insulating concrete forms, or ICFs, are solid interlocking blocks made of rigid, resilient foam called expanded polystyrene. ARXX's forms are made of two panels of the foam held in place by plastic or steel connectors. Once the building blocks are set, a rebar framework is inserted into the space between the foam panels and concrete is poured. The result: an airtight, insulated, fire-resistant structure.
