The combination of insulation and the concrete core acts as a mass wall and blocks air infiltration, allowing buildings to save significantly on their heating and cooling costs.
Fox Buck is a fully integrated, continuous insulation window and door buck for residential and commercial applications. The 1" x 1" notches create a dual barrier against drafts or moisture penetration. When installed properly, the concrete barrier protection is continuous around the entire opening. These barriers also anchor the Fox Buck to the wall with enough strength to hold in most weather conditions.
The buck is exactly 2" thick for easy measurements, and measures 48" high to match the height of the three blocks. It can be used conjuction with the internal "Energy Sticks" as well.
The buck features a 1 1/2" wide "fastening zone" for door and window attachments that runs the full height of the buck every 8" on center. Notches ensure proper alignment between the buck and the wall form. On the inside, Dual full-length 1" x 1" grooves create a solid concrete barrier against drafts and moisture. Circles are marked at 16" centers for sill cutouts and vibrator access.
The HV Clip is engineered to be perfectly balanced to secure Fox Blocks together. The clip works horizontally or vertically to give flat walls post concrete. Using the Fox Block HV Clip eliminates the need for truss wire completely.
