Rockwool vs Mineral Fibre – What’s The Difference?

Rockwool and mineral wool are both types of insulation materials that are commonly used in construction for their thermal and acoustic insulation properties. However, there is a difference between rockwool and mineral wool when it comes to fire resistance.

Rockwool is made from volcanic rock that has been melted and spun into thin fibres. These fibres are then formed into insulation batts or loose-fill insulation. Rockwool is naturally fire-resistant, as the melting and spinning process creates fibres that are able to withstand high temperatures without melting or releasing toxic fumes. Rockwool insulation is often used in areas where fire resistance is a critical concern, such as walls, floors, and ceilings.

Mineral wool, on the other hand, is made from a combination of rock, slag, and other mineral fibres. Like rockwool, mineral wool is naturally fire-resistant, and it is often used in the same types of applications. However, mineral wool is generally less dense than rockwool, which means that it may not provide as much insulation value per unit of thickness.

Both rockwool and mineral wool have excellent fire resistance properties, but rockwool is generally considered to be more effective at resisting high temperatures and preventing the spread of fire. However, both materials are suitable for use in construction projects where fire resistance is a critical concern, and the choice between the two will depend on factors such as cost, availability, and the specific requirements of the project.

In conclusion, both Rockwool and mineral fibre insulation are excellent choices for fire protection, and there are several brands on the market that offer these types of insulation, including Protecta, Rockwool, FSi, and Envirograf. Ultimately, the best choice will depend on the specific needs of the project, including factors such as cost, durability, and moisture resistance. However, with a range of options available, it is possible to find a high-quality insulation product that meets the needs of any project.
