High-performance sandwich panels designed for rapid installation in Bulgaria's pharmaceutical and medical research facilities.
Over the past decade, Bulgaria has evolved from a regional manufacturer into one of Eastern Europe's most dynamic hotspots for high-value industrial sectors. Driven by heavy investments in the Plovdiv Industrial Zone (Trakia Economic Zone), Sofia Tech Park, and coastal logistical gateways like Varna and Burgas, the demand for cleanroom infrastructure has reached unprecedented heights.
Key industrial expansions pushing this growth include:
Bulgaria operates under strict European Union construction products regulations. Standard construction panels are no longer sufficient for contemporary biological or high-performance electronic spaces. Cleanroom designs must offer absolute protection against dust particle generation, facilitate aggressive chemical sterilization, and withstand seismic structural activities characteristic of the Balkan region.
Any system installed in Bulgarian modern pharmaceutical units or research clinics must fulfill European fire protection classification EN 13501-1 (typically A2-s1, d0 for non-combustible panels) and airtightness properties under EN 12207 to ensure energy-efficient pressure differentials.

| Panel Core Material | Thermal Conductivity (W/m·K) | Fire Classification (EN 13501-1) | Acoustic Insulation | Optimal Applications |
|---|---|---|---|---|
| Hydrophobic Rockwool | 0.038 - 0.042 | Class A1 / A2 Non-Combustible | 32 - 35 dB | Pharmaceutical processing, chemical labs, firewalls |
| High-Density PIR / PUR | 0.020 - 0.024 | Class B-s1, d0 / B-s2, d0 | 25 - 28 dB | Cold rooms, food processing, sterile storage |
| Aluminum Honeycomb | Negligible (Metal Core) | Class A1 Non-Combustible | 22 - 25 dB | Semiconductor cleanrooms, microelectronics assembly |
| Paper Honeycomb / Silica | 0.045 - 0.052 | Class B / A2 depending on skins | 24 - 27 dB | General hospital partitions, lightweight medical ceilings |

Answers to common structural engineering, import regulations, and technical compliance questions.
Our sandwich panels are finished with specialized PVC, PVDF, or anti-static polyester coatings that inhibit micro-organism colonisation. These finishes undergo rigorous chemical testing to guarantee they do not deteriorate when exposed to regular sanitation via VHP (Vaporized Hydrogen Peroxide) or sodium hypochlorite.
All items shipped by Ningbo Jonas Build Co., Ltd. are packed in robust sea-freight steel-pallet crates. We provide the complete set of required documentation, including the commercial invoice, packing list, bill of lading, and CE Certificates of Conformity. This ensures smooth clearance at the customs offices in Burgas or Varna.
Yes. Our cleanroom wall and ceiling panels are specifically designed for modular surgical theaters and intensive care units. They feature integrated flush-joint systems that prevent dust buildup and provide high thermal and acoustic insulation parameters required by European healthcare regulations.
Rockwool core cleanroom panels provide superior fire resistance (A1 or A2 non-combustible classification) compared to PU/PIR, making them mandatory in cleanrooms containing high-voltage machinery or volatile solvents. However, for cold-chain clean spaces requiring optimal temperature insulation, PIR remains the preferred material.
Our cleanroom doors feature aluminum or stainless steel frames that sit perfectly flush with our 50mm, 75mm, or 100mm wall panel systems. This completely eliminates ledge surfaces that collect airborne particles and streamlines air pressure sealing using automatic drop seals.
Yes, all Jonas Build cleanroom sandwich panels undergo compliance testing covering BS EN 14509 (Self-supporting double skin metal faced insulating panels) and satisfy key criteria under ISO 14644-1 for cleanroom class cleanliness certifications.
