KS Flat Interior Panel

KS Flat Interior panels are the ideal solution for interior walls and ceilings for a range of applications including food and life science, pharmaceutical, bio-technology laboratories, research and advanced technology facilities.

  • KS Flat Interior panels offer the highest level of hygienic and contamination control
  • Features a flat, non-porous surface to both sides which aids cleaning and offers high levels of resistance to bacterial growth
  • KS Flat Interior panels utilize our KS joint design that ensures a tight, well designed vapor barrier in enclosures of any size
  • Available with CLEANsafe 120 coating for superior protection against corrosion
  • GREENGUARD Gold Certified
  • Certified material transparency and disclosure (QuadCore only)
  • Red List Free classification (QuadCore insulation core only)
