When it comes to the integrity of your ICF, nothing is superior to our double V-grooved engineered buck framing system. With the help of these dovetail V-grooves and metal flanges, the buck framing system stays in place and holds much longer than those without it. Designed for direct contact with concrete and non-corrosive to metals, we use a StrandGuard (LSL) engineered lumber treated with Zinc Borate for resistance to insects and decay. Another benefit of the StrandGuard (LSL) is that it will not cup, twist, or warp over time and can be cut to custom design specifications. The dovetail design of the grooves help lock the concrete in to place, while also eliminating air infiltration. The metal flange also provides many benefits along the lines of self-alignment with the walls and by supporting the ICF during the actual pouring of the concrete.
