CB4 Condensation Board

Control condensation and air infiltration in agricultural and utility buildings with this specialty board. The waterproof surface channels moisture to roof overhang areas for drainage, so stored materials, equipment, or livestock stay dry. A white undersiding also improves interior illumination.
