The difference between rock wool board and glass wool
Rock wool board and glass wool are both common artificial inorganic fiber insulation materials. They both have excellent thermal insulation, sound absorption and noise reduction, fire retardant and other properties, but there are also some differences in raw materials, production processes, performance characteristics, etc.

1. Raw materials:

Rock wool board: Made of basalt as the main raw material, it is made by high-temperature melting and centrifugal blowing.

Glass wool: Made of quartz sand, limestone, dolomite, etc. as the main raw materials, it is made by high-temperature melting and centrifugal blowing.

2. Production process:

Rock wool board: The production process is relatively complicated, and it needs to go through high-temperature melting, centrifugal blowing, curing and molding and other processes.

Glass wool: The production process is relatively simple, mainly through high-temperature melting, centrifugal blowing and other processes.

3. Performance characteristics:

Characteristics Rock wool board Glass wool
Thermal insulation performance Slightly lower than glass wool Slightly higher than rock wool board
Sound absorption and noise reduction performance Slightly lower than glass wool Slightly higher than rock wool board
Fire retardant performance Better than glass wool Slightly lower than rock wool board
Chemical stability Acid and alkali corrosion resistance Acid and alkali corrosion resistance
Environmental protection Does not contain asbestos and other harmful substances Does not contain asbestos and other harmful substances
Price Slightly higher than glass wool Slightly lower than rock wool board

4. Application areas:

Rock wool board: widely used in thermal insulation, sound absorption and noise reduction, fire retardant, etc. in construction, industry, shipbuilding and other fields.

Glass wool: widely used in thermal insulation, sound absorption and noise reduction, etc. in construction, industry, home appliances and other fields.

In short, rock wool board and glass wool are both excellent insulation materials, but there are also some differences in raw materials, production processes, performance characteristics, etc. Users can choose the appropriate material according to their own needs.

Here are some common questions about rock wool board and glass wool:

Which is better, rock wool board or glass wool?

Rock wool board and glass wool each have their own advantages and disadvantages, and users can choose the appropriate material according to their own needs.

Which is more expensive, rock wool board or glass wool?

The price of rock wool board is generally slightly higher than that of glass wool.

How long is the service life of rock wool board and glass wool?

The service life of high-quality rock wool board and glass wool can reach more than 50 years.
