What it is

Product overview

QuadCore KS Flat Interior is an insulated interior wall-and-ceiling panel for controlled environments. Kingspan’s current US catalogue identifies flat nonporous faces, joint and vapor-control features, and an optional CLEANsafe 120 coating for selected corrosion exposures.

The panel may be considered in cleanrooms, data centers, pharmaceutical, biotechnology, life-science, and advanced-technology facilities. Hygiene, vapor, pressure, fire, finish, washdown, chemical exposure, support, suspension, and penetration details remain project-specific.
