The invention presents a temporary protective containment barrier system tailored for construction and demolition. Comprising multiple wall members, each integrates vertical wall panels affixed to adjustable stud members, forming vertical partitions. These stud members feature cantilevers at their upper limits. The system incorporates noggins connecting adjacent stud members and includes ceiling joists and panels. Cantilevers are linked through ceiling joists. Structural fasteners secure noggins and/or ceiling joists. This modular system offers adaptable protection during construction and demolition activities, facilitating containment and safety measures.
