Modular wall systems can be erected faster than cement block or gypsum wallboard partitions and envelopes while offering design flexibility. Metl-Span’s ThermalSafe NC insulated metal wall panels comprise a 3”-thick structural mineral wool core and offer an R-11 thermal resistance. The panels are bonded to steel facers and can be erected in a single step by workers. They are designed for use in non-combustible interior or exterior applications. The 42”-wide panels are available in 8’ to 40’ lengths.
