Cleanroom Wall and Ceiling Systems
Rock Wool Cleanroom Sandwich Panel
A steel-faced modular panel with a dense hydrophobic rock wool core, designed for cleanroom walls and ceilings that need a smooth hygienic finish, robust mineral insulation and practical tongue-and-groove installation.
- Dense Rock Wool Core
- Hygienic Steel Facings
- Sealed Modular Joints
- Wall or Ceiling Use
Product Introduction
This cleanroom panel bonds pre-painted galvanized steel facings to high-density rock wool lamellas and closes the perimeter with formed steel or aluminum profiles. The mineral core gives the panel a solid feel while the smooth external skins provide a non-shedding surface for routine wiping. Concealed tongue-and-groove edges create straight, sealant-ready joints and allow vertical or horizontal installation. It is a practical enclosure material for controlled rooms where cleanability, acoustic comfort and mineral-core construction are valued together.
Key Features
Bonded steel skins distribute handling loads and maintain a flat finished wall surface.
Enclosed edges isolate the fibrous core from the controlled environment.
Tongue-and-groove joints reduce visible gaps and provide a consistent sealant line.
Individual modules can be removed when a wall layout or service route changes.
Customer Product Concerns
Customer concerns usually focus on exposed fibres, joint cleanliness, wall flatness and the handling of mineral-core panels.
Fibrous insulation can contaminate a clean area when panel edges are left exposed.Metal facings and closed perimeter profiles fully separate the rock wool core from the room.
Uneven joints create ledges that collect residue during routine cleaning.Precision tongue-and-groove edges form straight joints that accept a continuous hygienic seal.
Large mineral-core panels can flex or twist during movement and installation.Bonded facings, controlled dimensions and balanced lifting points protect panel flatness.
Conventional partitions are difficult to open when new utilities are added.Demountable panel modules allow selected wall sections to be removed and reinstalled.
Typical Applications
Pharmaceutical production room wallsMedical-device assembly clean areasLaboratory partitions and technical corridorsElectronics cleanroom walls and ceilingsHygienic food-processing enclosures
