Recyclable And Eco-friendly Rock Wool Boards With High Waterproof Performance

Hydrophobic rock wool board is a thermal insulation material that improves its water resistance through special processes, such as adding hydrophobic agents. It retains the core advantages of rock wool while offering enhanced moisture resistance and durability. The hydrophobicity of rock wool panels is a core property that plays a vital role in withstanding complex weather and harsh environments, primarily by preserving core functionality, extending service life, and ensuring structural safety.

Key Advantages

Weather Resistance: Resists rain, snow, and high humidity to prevent insulation failure by preventing moisture penetration that would otherwise replace insulating air pockets.
Freeze-Thaw Protection: Combats freeze-thaw cycles to avoid physical damage from expanding ice that can cause cracking and structural loosening.
Mold & Corrosion Prevention: Inhibits mold growth and corrosion by isolating humid environments from building materials and metal components.
Structural Stability: Maintains integrity in extreme weather conditions by preventing moisture-related weight gain and structural deformation.
Cost Efficiency: Reduces maintenance costs and extends service life by eliminating moisture-related problems that require frequent repairs or replacements.

Waterproof Performance Comparison

Material	Waterproof Principle	Water Absorption Rate	Applicable Environment	Limitations	Waterproof Lifespan
Hydrophobic Rock Wool Board	Hydrophobic treatment reduces water adsorption	≤5% (≤3% for high-quality products)	High-humidity insulation scenarios	Requires combination with other waterproof layers	15-20 years
Concrete	Dense structure formed by adjusting mix ratio	Impermeability grade P6-P12	Structural waterproofing	May crack under stress	10-30 years
Coating Types	Forms continuous waterproof film	Almost no water absorption	Small-area scenarios	Breathability/UV resistance issues	10-15 years
Metal Materials	Non-absorbent by nature	0%	Large venues	Joints prone to seepage	20-50 years
