Moisture-proof mineral wool ceiling tile

Moisture-proof mineral wool board (mineral wool sound-absorbing and moisture-proof ceiling)


Moisture-proof mineral wool board sample


Mantianxing moisture-proof mineral wool board 1. Basic definition: Moisture-proof mineral wool board is made from slag wool fibers, with moisture-proof agent mixed in during production and a moisture-proof coating/film on the surface, distinguishing it from ordinary mineral wool board. Core function: Reduce water absorption in humid environments, prevent ceiling subsidence, warping, and mold growth.
⚠️ Important reminder: moisture-resistant ≠ waterproof! Do not expose to direct water for extended periods; not recommended for use in bathrooms or shower areas.
II. Core Indicators [RH Moisture Resistance Level (Industry Standard)] The RH value represents the long-term stable relative humidity tolerance of the board. RH80: economical moisture resistance, suitable for long-term humidity levels up to 80%, ideal for ordinary offices, corridors in the south. RH90: conventional engineering moisture resistance, suitable for long-term humidity levels up to 90%, ideal for restaurants, hospital clinics, and ground-floor shops. RH95: high moisture resistance, suitable for long-term humidity levels up to 95%, ideal for basements, kitchen perimeters, and coastal wet areas. RH99/RH100 (high-end laminated models): the highest level, ideal for areas around swimming pools, changing rooms, laboratories, and direct comparison with ordinary mineral wool boards. Table Item | Ordinary Mineral Wool Board | Moisture-Resistant Mineral Wool Board (RH90+) | Water Absorption | High, extremely prone to water absorption and softening | Low, fibers encapsulated by moisture-resistant agent | Long-term Humidity Upper Limit | ≤70%RH | 90%~99%RH | Moisture Manifestations | Water absorption, sagging, deformation, mold growth | Less prone to sagging, dimensional stability | Price | Cheap | 15%~40% more expensive than ordinary boards | III. Main Performance | Fire Resistance: A2-s1,d0 / Class A non-combustible, meets public decoration fire safety standards | Sound Absorption and Noise Reduction: NRC 0.50~0.85, reduces spatial echoes | Lightweight, compatible with T-shaped painted joist exposed installation / concealed installation with step-down | Environmental Protection: Asbestos-free, formaldehyde meets E1 standard | Thermal Insulation and Light Reflection: High light reflection rate, saves lighting | IV. Conventional Specifications (General for Engineering) | Size: 600×600mm, 600×1200mm (mainstream) | Thickness: 14mm / 15mm / 16mm | Board Edge Type: Flat (right angle, exposed joist T-bone) | Step-down board (bevel angle, concealed / semi-concealed) | Surface Pattern: Starry Sky, Caterpillar, Rainflake, Micro-Hole Flat, Sandblasted Surface | V. Applicable & Prohibited Scenarios | Recommended for use in ground-floor shops, office buildings, hospitals, school classrooms, restaurants, basement computer rooms, shopping malls, coastal projects, spaces prone to moisture during rainy seasons | Not recommended for enclosed shower rooms, sauna rooms, areas with long-term water spray; such environments prefer three-proof boards / aluminum buckle boards / fiber cement boards
