Rock Wool Insulated Sandwich Panel – Building Envelope Grade
Product Overview
Rock wool insulated sandwich panel is a prefabricated composite building panel consisting of two color coated steel face sheets bonded to a non-combustible rock wool insulation core. It integrates structural cladding, thermal insulation, fire resistance and acoustic performance into a single modular component, enabling fast, clean construction of high-performance building envelopes. This grade is the standard solution for industrial, commercial and public buildings requiring energy efficiency and fire safety.
Why Choose CNB Insulated Sandwich Panels?
We manufacture sandwich panels on continuous lamination lines with strict control over bond strength, core density and dimensional accuracy. We use only high-quality PPGL face sheets and premium rock wool core to ensure consistent thermal, fire and structural performance. Every panel undergoes quality inspection for straightness, bond integrity and surface finish, delivering ready-to-install panels that reduce on-site labor and construction time.
