Leadsun Rock Wool Insulation Board is a Class A1 non-combustible material designed for thermal and acoustic insulation in roofs, walls, HVAC systems, and pre-engineered buildings. With excellent fire prevention, moisture resistance, good durability, and dimensional stability, it ensures long-lasting performance in various environmental conditions.
- High Fire Resistance: Class A1 non-combustible material, suitable for fire barriers and high-temperature applications up to 1000°C.
- Excellent Thermal Insulation: Low thermal conductivity (≤0.040 W/m·K) ensures effective heat retention and energy savings.
- Superior Acoustic Performance: Effectively reduces noise transmission, ideal for soundproofing in buildings and industrial equipment.
- Water Repellent & Moisture Resistant: Hydrophobic treatment (≥98%) prevents water absorption, maintaining insulation performance in humid environments.
- High Strength & Stability: Good compressive and tensile strength ensure durability and long-term structural integrity.
- Easy to Install: Can be easily cut, shaped, and installed on walls, roofs, ducts, and pipelines.
- Environmentally Safe: Free from asbestos and CFCs, safe for indoor and outdoor use.
- Width (W): 600 - 1200 mm
- Thickness (T): 25 - 150 mm
- Length (L): 1200 - 2400 mm
- (Custom sizes and densities are available upon request.)
- Building Insulation: Roofs, walls, curtain walls, partition systems, and pre-fabricated houses.
- Fire Protection: Fire barriers, fire-rated doors, structural fireproofing, and industrial furnace lining.
- Industrial Insulation: HVAC ducting, boilers, pipelines, equipment insulation, and poultry farms.
- Acoustic Control: False ceilings, studios, theaters, offices, and industrial noise reduction.
- Marine & Transportation: Insulation for ships, trains, and automotive heat shielding.
