Engineered to deliver optimum structural rigidity, chemical resistance against repeated VHP cycles, and A-grade fire protection.
Navigating the stringent demands of Flanders' biotech clusters, Wallonia's biopharma corridors, and Leuven's nanotech ecosystem.
Belgium holds a commanding position as one of Europe's most concentrated pharmaceutical, vaccine manufacturing, and biotechnology centers. With global biopharma hubs situated across Flanders (such as Ghent and Puurs) and Wallonia (including Charleroi and Wavre), alongside world-renowned semiconductor research institutions in Leuven, local cleanroom infrastructure is subjected to some of the strictest clean-envelope protocols in the world.
In high-grade aseptic cleanrooms (EU GMP Grade A/B) and sub-nanometer semiconductor fab lines (ISO Class 3/4), the choice of the cleanroom panel core material directly influences particulate containment, micro-vibration damping, fire reaction classes under EN 13501-1, thermal insulation coefficients (U-values), and resistance against continuous biodecontamination protocols such as Vaporized Hydrogen Peroxide (VHP).
K-STONE provides certified modular cleanroom panel systems designed specifically to satisfy both Belgian fire safety codes and European contamination control strategies (CCS), ensuring longevity, rapid site assembly, and seamless flush integration.
Fabricated with hexagonal 3003-grade aluminum foil cells. Provides ultra-high strength-to-weight ratio, exceptional planarity, zero outgassing, and non-combustible performance. Favored across Leuven and Antwerp microelectronics, optics, and ISO 14644-1 Class 3-5 cleanrooms.
Combines high-density hydrophobic basalt rockwool with reinforcement gypsum boards. Delivers up to 2-hour fire resistance ratings (EI120 / REI120 under EN 13501-2) with excellent thermal insulation and acoustic dampening for high-output HVAC pharmaceutical production plants.
A breakthrough fireproof and moisture-proof core board. Unlike traditional magnesium oxychloride boards, MOS eliminates halogenation and chloride-induced steel sheet corrosion while maintaining superior bending strength, mold resistance, and flatness for sterile suites.
The revised EU GMP Annex 1 regulations place stringent demands on the cleanroom envelope, explicitly requiring architectural surfaces to be smooth, impervious, free of cracks, and resistant to frequent cleaning agents and sporicidal disinfectants. In Belgian aseptic manufacturing suites, walls and ceilings constructed with sub-optimal cores often suffer from core deformation, delamination, or micro-cracking at joints due to pressure differentials and humidity cycling.
Our sandwich panels leverage double-component polyurethane structural adhesives applied with automated continuous laminators. This ensures a permanent bond between the core material (such as hollow magnesium, mineral wool, or aluminum honeycomb) and the pre-painted galvanized steel or anti-static PVDF-coated face sheets.
Whether configuring clean corridors in Walloon cell-therapy labs or Class A laminar flow zones in Flemish vaccine packaging facilities, K-STONE panels guarantee structural integrity under continuous ±50 Pa differential pressures and complete resilience against cyclic VHP fumigation.
