Used to keep potentially harmful water out of structure during construction, ForceField™ consists of engineered wood sheathing panels laminated with air and water barrier. Panel joints are taped with seam tape once wall sheathing is installed on structure to help prevent air infiltration and leaks. Available in 7/16 CAT thickness and sizes of 4x8, 4x9, and 4x10 sizes, panels install akin to standard plywood or OSB sheathing panels. Tape comes in 3 in. x 165 ft rolls.
