It just dawned on my that my ICF walls are 12 inches wide, and the widest jamb I can get is 9' for my windows. We're going with stucco on the ICF, and I was wondering. A specific type that is made of portland cement and recycled styrofoam which results in a screen-grid type ICF. Thickness is 10 inches before stucco exterior and plaster interior. I have 3 jeld-wen casement windows. Openings in ICF walls must stop the flow of concrete and provide attachment points for the installation of doors or windows. This process is called bucking. It is the same concept as completing end walls or bulkhead walls. The bucking size and type is usually determined by the type of opening and the needs of the product to be installed. The Installation Process. Building with insulated concrete forms is a simple process that is far less labor intensive than most traditional construction methods.

ICF Wall Opening This page will discuss design considerations of ICF doors & windows in an ICF wall as well as material options and construction of bucking for ICF Door & Window Openings. Designing Openings and Spacing for ICF Windows & Doors Anything is possible with ICFs, but using the guidelines below can prevent additional engineering requirements or challenges during construction. • Openings should be spaced not less than 12”. If less than 12”, openings should be mulled or framed as a single opening. If openings must be spaced closer, extra care should be taken to ensure complete consolidation between openings and add additional rebar as needed.

• Provide minimum space for adequate consolidation of concrete beside openings. IRC & IBC require internal vibration for all walls. • Mulling smaller openings together may reduce overall vertical rebar beside openings (through eliminating multiple openings).

Place rebar as scheduled beside openings (typically 2 bars on each side of opening).

If openings are spaced closer, extra care should be taken to ensure complete consolidation in the corner form with additional bracing and strapping. The corner form and buck may try to separate from each other unless braced and strapped properly. • Jambs for garage doors and other large openings should be a minimum of 12”. If narrower, lintel steel should still extend into adjacent walls the required 24” beyond opening on each side.

• Use pre-bent steel for wrapping corner lintels. Ensure 40X bar diameter overlap if discontinuous steel is used. • Extra care should be taken to ensure complete consolidation in the jambs. IRC & IBC require internal vibration for all walls.
