Cleanroom Wall and Ceiling Systems
Fire-Rated Rock Wool Cleanroom Panel
A steel-faced rock wool cleanroom panel configured for fire-rated wall and ceiling assemblies, combining non-combustible mineral insulation, protected joints, controlled service openings and smooth hygienic room surfaces for clean manufacturing interiors.
- High-Density Stone Wool Core
- Fire-Rated Assembly Construction
- Protected Interlocking Joints
- Hygienic Steel Surfaces
Product Introduction
Fire-Rated Rock Wool Cleanroom Panels use vertically oriented stone-wool lamellas between steel facings and incorporate joint, frame and fixing details that preserve integrity during fire exposure. The panel is treated as part of a complete wall or ceiling assembly rather than as an isolated core material. Higher density and increasing panel thickness support longer fire-resistance configurations, while metal edge closures protect the core and maintain a clean internal finish. The system is suitable for controlled areas that require both hygienic surfaces and compartmentation using tested mineral-core construction.
Key Features
Vertical lamella orientation improves through-thickness mechanical support between the steel skins.
Joint geometry limits direct flame and hot-gas paths between adjacent modules.
Protected service openings preserve the continuity of the fire-separating layer.
Smooth room-side steel remains compatible with normal cleanroom wiping and disinfection.
Customer Product Concerns
Customers need the panel thickness, joint, support spacing and penetration details to work together as one fire-separating construction.
A non-combustible core alone does not stop hot gases passing through an open joint.Profiled interlocks, mineral packing and compatible fire-stop seals protect the full panel connection.
Unprotected service penetrations can bypass the fire-resisting wall.Tested collars, sleeves and perimeter seals close openings around cables, ducts and pipes.
Insufficient density or thickness reduces the available fire-resistance configuration.The selected stone-wool density and panel depth are matched to the required assembly duration.
Fire-focused materials can introduce rough surfaces into a hygienic room.Continuous steel skins and closed edges keep the mineral insulation outside the cleanable surface.
Typical Applications
Pharmaceutical fire-compartment partitionsClean corridors adjoining plant roomsBattery and electronics controlled areasLaboratory walls beside utility zonesMineral-core cleanroom ceilings
