There are significant differences between wool board and glass wool board in many aspects. The following is a specific comparison:

Rock wool board Glass wool board
Main raw materials Basalt Glass fiber
Production process Pendulum method Three-dimensional interweaving Flat weaving method
Acidity coefficient Usually above 1.6 Far below 1.6
Strength Meets the requirements for wall mounting (compression strength ≥40kPa, tensile strength perpendicular to the board surface ≥7.5KPa) Does not meet the requirements for wall mounting (both strength indicators are 0)
Fire resistance time/heat resistance performance Fire resistance time can reach 4 hours, maximum temperature resistance 1000 degrees Celsius Working temperature above 250 degrees Celsius
Construction method Adhesive nail combination, easier to construct Anchoring fixation, more difficult to construct
Dimensional stability High stability Poor dimensional stability, high water absorption, easy to expand
Hydrophobic performance Some products can reach high hydrophobicity –
Application areas External wall fireproof insulation materials, high-temperature thermal pipelines or power equipment insulation Wall insulation, floor sound insulation, pipe insulation, cold storage insulation, vehicle sound insulation, etc.

Here is a detailed explanation of these differences:

Main raw materials: rock wool board uses basalt as the main raw material, while glass wool board uses glass fiber as the main raw material.

Production process: rock wool board adopts the three-dimensional interweaving process of pendulum method, which makes rock wool board have better strength and stability. Glass wool board is produced by flat weaving method.

Performance parameters:

Acidity coefficient: The acidity coefficient of rock wool board is usually above 1.6, while the acidity coefficient of glass wool board is much lower than 1.6. High acidity coefficient means better strength and durability.

Strength: rock wool board meets the strength standard required for wall, while glass wool board does not.

Fire resistance time/temperature resistance: rock wool board has longer fire resistance time and higher temperature resistance.

Construction and maintenance:

Construction method: rock wool board is constructed by bonding and nailing, which is easier. Glass wool board is usually fixed by anchoring, which is relatively difficult to construct.
Dimensional stability: rock wool board has higher dimensional stability and is not easy to expand or shrink. Glass wool board has poor dimensional stability, high water absorption, and is easy to expand.
Application areas: rock wool board is mainly used for exterior wall fireproof insulation materials and thermal insulation of high-temperature thermal pipelines or power equipment. Glass wool board is widely used in wall insulation, floor sound insulation, pipeline insulation, cold storage insulation, and vehicle sound insulation.
In summary, there are significant differences between rock wool board and glass wool board in terms of raw materials, production process, performance parameters, construction and maintenance, and application areas. When choosing, users should weigh and choose according to their needs and actual conditions.
