Cleanroom Wall and Ceiling Systems
Double MgO Rock Wool Cleanroom Panel
A balanced composite cleanroom panel with rock wool insulation and one magnesium oxide reinforcement board beneath each steel face, providing a firmer substrate and greater dimensional stability than a basic mineral-wool panel.
- Two MgO Reinforcement Layers
- Balanced Composite Structure
- Rigid Mineral Core
- Protected Panel Edges
Product Introduction
The Double MgO Rock Wool Cleanroom Panel uses a symmetrical internal build-up: a high-density rock wool center, an MgO board on each side and cleanable metal outer facings. The rigid boards spread local pressure across the softer mineral core and create firm substrates beneath both room surfaces. This balanced construction improves handling stability and is useful around tall wall modules, ceiling openings and frequently integrated services. Four-sided framing protects the layered core, while flush modular joints maintain a uniform cleanroom finish.
Key Features
Rigid inorganic layers improve resistance to local dents around fittings and openings.
Rock wool remains fully enclosed behind the MgO boards and external steel skins.
Four-sided edge framing protects the multi-layer core during transport and assembly.
Firm internal substrates simplify factory preparation of accurately positioned service cut-outs.
Customer Product Concerns
Buyers select this construction when ordinary rock wool panels lack the surface rigidity needed on both sides.
Soft core areas can compress around openings or frequently handled panel edges.Two rigid MgO layers distribute local pressure before it reaches the rock wool center.
Unequal internal layers can make a composite panel bow toward one face.The mirrored reinforcement build-up keeps stiffness more evenly balanced across the panel.
Heavy wall accessories need firmer support than mineral wool alone can provide.MgO substrates improve fastening support, with dedicated inserts used for concentrated loads.
Layered core materials can be damaged at unprotected perimeter cuts.Closed edge profiles shield the MgO boards and rock wool throughout handling and installation.
Typical Applications
Biopharmaceutical cleanroom partitionsLaboratory walls with integrated servicesRigid cleanroom ceiling modulesHospital sterile-support roomsTall modular wall systems
