Abstract
An insulating fire and blast resistant window and door buck is described that is designed for use with an insulated concrete wall form. The window and door buck described provides a core of concrete for fire and blast protection while also providing structural concrete for attaching window and door elements. In some embodiments, the window and door buck comprises two pieces of insulation that are separated by a gap and held together by a tie piece. The insulation pieces are proportioned to so that an alignment element fits inside the cavity of the wall form. When the buck is placed in an insulated wall form and concrete is poured into the form a strip of concrete fills the gap, resulting in a fire and blast resistant wall.
