Performance Characteristics

Class A non-combustible material (highest fire rating)
Excellent thermal insulation properties
Effective noise reduction capabilities
Superior hydrophobic properties (water absorption ≤5%)
High chemical stability and corrosion resistance
Environmentally friendly and non-toxic

Product Description

Our eco-friendly fireproof rock wool boards are manufactured from natural basalt and diabase rocks melted at temperatures exceeding 1500°C. These inorganic mineral boards feature Class A non-combustible properties, fundamentally eliminating ignition risks. Unlike combustible plastic insulation materials, rock wool maintains structural stability at high temperatures (melting point ≈1000°C) without emitting toxic fumes, providing critical fire protection in building applications.

Key Advantages

The fibrous, porous structure ensures low thermal conductivity for superior insulation performance while maintaining energy efficiency. Hydrophobic variants offer reliable moisture resistance with water absorption rates ≤5% (≤3% for premium grades). The material's chemical stability ensures long service life, and its non-toxic composition supports sustainable building practices.

Applications

Building insulation for walls, ceilings, and partition walls
Industrial furnace and kiln insulation
Data center server room temperature control
Transportation insulation (train compartments, bus bodies)
Cold storage facility insulation
Historic building renovations

Fire Resistance Performance Comparison

Building Materials	Fire Performance Class	Fire Resistance Rating	Characteristics When Burning	Applicable Scenarios
Rock Wool Board	Class A1 (Non-combustible)	1-4 hours	Does not burn, maintains structural stability	Wall insulation, fire barriers
Expanded Polystyrene (EPS)	Class B2 (Combustible)	0.1-0.3 hours	Releases toxic fumes, fast fire spread	Low-rise buildings (with fire protection)
Polyurethane Foam (PU)	Class B3 (Flammable)	<0.1 hours	Highly flammable, releases toxic gases	Restricted non-exposed uses
Glass Wool Board	Class A1 (Non-combustible)	0.5-2 hours	Stable at high temperatures	Duct insulation, partition walls
