Use ICF Window, Door Bucks for Faster Construction and Improved Thermal Envelope
Insulated concrete forms (ICFs) are rigid plastic foam forms that hold concrete in place during curing and remain in place to serve as thermal insulation for concrete walls. For many insulated concrete form (ICF) systems, one weak point has been door and window bucks. Often the ICF construction required using dimensional lumber, vinyl or steel to create a nailing surface to mount doors and windows, and to seal the blocks where they form an opening. This white paper, sponsored by Fox Blocks, explores the need for an ICF system that incorporates foam bucks in the system for a continuous insulated surface.
