BuildBuck ICF Door & Window Bucking brings the insulation properties of EPS foam together with embedded plastic webs to create a strong seamless transition from ICF walls to door and window openings. The buck features three primary attachment areas across the face of the buck every 6-inches in the center and on each side as well as a full-length attachment on each side. Foam guides properly align BuildBuck and the ICF blocks.

A molded-in sealing member works with flashing to seal against moisture intrusion. The full length molded tape measure and cut lines make cutting the buck to size simple and straightforward. Foam guides properly align BuildBuck and the ICF blocks. BuildBuck is available for 4″, 6″, and 8″ ICF core widths.
