Product Description

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.

Key Features

Excellent Hydrophobicity: Water absorption rate typically below 5% (under 3% for premium products), preventing liquid penetration even in high humidity
Superior Fire Resistance: Non-combustible (Class A rating), produces no toxic fumes at high temperatures
Thermal Insulation: Low thermal conductivity due to numerous closed pores between fibers
Chemical Resistance: Resistant to acid, alkali, and environmental corrosion
Structural Stability: Maintains shape in humid conditions without loosening or cracking

Applications

Ideal for moisture-resistant applications including:

External wall insulation systems
Roof insulation layers
Underground engineering (subways, tunnels)
Outdoor industrial pipe insulation
High-humidity interior spaces (bathrooms, cold storage)

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
