Product DescriptionProduct DescriptionComposite Rock Wool BoardThis is the Composite Rock Wool Board, is commonly used in construction and industrial fields of functional materials, the core by the rock wool core material (yellow part, to basalt and other raw materials, made of high-temperature melting fibrosis) and protective surface layer (gray and white part, mostly fiber cement board, calcium silicate board, etc.) composite and become.Key features Thermal insulation: rock wool porous structure of static air storage, low thermal conductivity, can effectively block heat transfer, to help buildings, equipment, energy saving.Fireproof and flame retardant: rock wool itself is non-combustible, does not flare up in case of fire, and does not release toxic gases, which improves the fire safety of application scenarios.Sound absorption and noise reduction: the porous structure can absorb and scatter sound waves, reduce the spread of noise, suitable for places with requirements for acoustic environment.Mechanical stability: the composite surface layer enhances the structural strength, better resistance to pressure and deformation, and is not easy to be damaged in construction and long-term use.Material Compositionbasalt rock and slagFire ResistanceA1 or A2Thermal Insulation0.035–0.042 W/m·KWater Resistancerepels waterSound InsulationHighDurabilityResistant to agingMechanical StrengthHigh compressiveAfter-sales serviceFree Technical Guidance, 12 MonthsCharacteristicsDurable,Easy to Install,Fierproof,Flame Retardant,Heat Insulation,Noise ReductionMaximum working temperature500°CMaterialBasaltTransport packagingCartons/Bags/PalletsTrademarkszhenmeiPlace of originChinaColorYellowUseWallMaterial compositionbasalt rock, slag, and binderThermal Conduct~0.035-0.042 W/m·KFire Resistance>1000°CSound AbsorptionNRC 0.75-0.95Water RepellencyHydrophobicDensity40-200 kg/mApplicationsBuilding insulation (walls, roofs),Main ProductCompany ProfileCompany Profile Zhejiang Huahang Thermal Insulation Products Co., Ltd. is a subsidiary under the group, located in Hangzhou, Zhejiang.

Your inquiries and purchases are warmly welcomed!AdvantageCertificationsAfter Sales ServicePackaging & ShippingFAQ1. Which insulation material is best for my home (exterior walls/roof/interior walls)?Exterior walls: Fireproof Class A rock wool boards or foam cement boards (durable). Roof: XPS extruded boards (waterproof and pressure-resistant) or polyurethane spray (seamless insulation). Interior walls: Lightweight EPS boards or fiberglass wool (space-saving).2.How are fire resistance ratings classified?Class A: Non-combustible (e.g., rock wool, foam cement).Class B1: Flame-retardant (e.g., fire-resistant EPS/PU).For homes, at least Class B1 is recommended; public buildings require Class A.3. Are your products eco-friendly?Do you have test reports? Available certifications: Fire resistance test reports (GB 8624). Eco-labels (e.g., green building materials, formaldehyde emission tests).4. What is the price per square meter?Example price ranges: EPS boards: ￥20–40/m XPS boards: ￥40–80/m Rock wool boards: ￥60–120/m (Varies by thickness, density, and brand.)5. How do I calculate how much material I need?Formula: Area (m2) × Thickness (cm) ÷ Package volume. Example: For 100m2 walls with 5cm EPS boards: 100 × 0.05 = 5m2 (confirm package specs).6. What should I know for DIY installation?Key steps: Clean the base surface (no dust or grease). Ensure tight seams between boards. Use specialized adhesives and anchors. 7. How long does the insulation last?Typically 20–30 years, but note: Organic materials (e.g., EPS) degrade under UV exposure. Inorganic materials (e.g., rock wool) must stay dry. 8. What if the material gets damaged or detaches?Warranty coverage (usually 1–5 years) for repairs. Small repairs can use structural adhesive. 9. Does winter installation affect performance?In low temperatures (<5°C): Use winter-grade adhesives. Avoid rain/snow during installation.
