Rock Wool Sandwich Panel for Hospital
Fire resistance: Rock wool is made of minerals such as basalt and is a Class A non-combustible material. It can effectively prevent the spread of fire and improve building safety.
Thermal insulation: Rock wool has a low thermal conductivity, which can effectively reduce heat transfer, improve building insulation effect, and reduce energy consumption.
Sound insulation: The porous structure of rock wool can absorb sound waves and reduce noise transmission, and is suitable for places where sound insulation is required.
Corrosion resistance: Rock wool has stable chemical properties, is resistant to acid and alkali corrosion, is suitable for a variety of environments, and has a long service life.
High compressive strength: Rock wool has a tight structure and good compressive resistance, and is suitable for occasions that require load-bearing.

Hospitals demand the highest standards in construction materials—combining fire safety, hygiene, acoustic control, and thermal performance. The rock wool sandwich panel has become a cornerstone solution in healthcare facility design due to its non-combustibility, anti-bacterial properties, and structural efficiency.
This article explores the engineering principles, material specifications, compliance requirements, and practical considerations of using rock wool sandwich panels in hospital environments, with a focus on optimizing safety, performance, and sustainability.
What Is a Rock Wool Sandwich Panel for Hospitals?
A rock wool sandwich panel is a prefabricated composite panel composed of:
Inner and outer metal facings (usually coated galvanized or aluminum steel sheets),
A non-combustible core of high-density mineral (rock) wool, known for its fire resistance and thermal insulation properties.
In hospitals, these panels serve in applications including:
Partition walls
Cleanroom walls and ceilings
Fire-rated corridors
HVAC enclosures
Emergency escape routes

Engineering & Structural Performance
1. Fire Protection
Hospitals are high-risk environments in terms of fire safety. Rock wool’s melting point > 1000°C offers:
Flame spread resistance
Non-toxic smoke emission
Compartmentation for fire zones
Compliant with:
EN 13501-1
NFPA 285
FM Approvals 4880/4881 (upon request)
2. Acoustic Control
Acoustic privacy is critical for wards, operating rooms, and intensive care units. Panels with rock wool cores achieve:
STC rating up to 32–35 dB (per ASTM E90)
Damping of airborne noise and equipment vibration
3. Thermal Regulation
Maintaining consistent interior temperatures supports infection control and patient comfort:
U-value as low as 0.24 W/m²·K at 100mm thickness
Works in tandem with HVAC systems to reduce load
4. Structural Load Bearing
Can span up to 3.5m–5m unsupported, depending on thickness
Suitable for suspended ceiling grids and modular wall systems
Offers high compressive strength: ≥ 80 kPa
Regulatory and Hygiene Considerations
Hospitals require compliance with multiple national and international health and safety codes:
| Standard / Regulation | Scope |
|---|---|
| EN 14509 | Self-supporting metal-faced insulated panels |
| ISO 14644 | Cleanroom classification |
| WHO Guidelines for Infection Control | Surfaces must be easy to clean, non-porous, and antimicrobial |
| ASHRAE 170 | Ventilation for healthcare facilities |
| NFPA 101 (Life Safety Code) | Fire barrier and compartmentation |
Installation Best Practices
Panel Orientation:
Vertical installation for walls, horizontal for ceilings
Sealants:
Use non-toxic, low-VOC, mold-resistant silicone for all joints
Fixing System:
Hidden fastener systems to avoid dust accumulation
EPDM gaskets for airtight sealing
Air Leakage Rate:
Should not exceed 0.5 m³/h·m² at 50 Pa (per ISO 9972)
Use Case: Modular Hospital Construction
Project Type: Emergency Field Hospital
Location: Southeast Asia
Solution: 100mm rock wool sandwich panels with PVDF-coated steel
Result:
Fire-rated walls (4 hours)
Sound privacy in wards (STC 30)
Installation completed in 25% of typical construction time
Common Questions
Q1: Are rock wool panels suitable for surgical cleanrooms?
Yes. When combined with sealed edge treatments and antimicrobial coatings, these panels meet ISO Class 7–8 requirements.
Q2: Can these panels support ceiling-mounted medical equipment?
Yes. When properly reinforced, panels can support non-structural loads such as surgical lights or sensors.
Q3: Are they safe in MRI rooms?
Use of non-ferromagnetic facings (e.g., aluminum or stainless steel) is required for MRI-safe zones.
Q4: How do they compare to EPS panels in fire performance?
Rock wool panels are non-combustible (Class A1), while EPS is combustible and not suitable for hospital use under most fire codes.
Conclusion
Rock wool sandwich panels offer unmatched advantages in hospital settings—providing critical fire safety, acoustic control, hygiene compliance, and thermal insulation in one engineered solution. They meet stringent building codes, infection control protocols, and support modular construction methods ideal for healthcare facilities under time and quality constraints.
