Whilst both materials offer strong performance, rock mineral wool is the superior option, as across almost every aspect of performance, the material delivers greater results.

Mineral wool and rock wool have similar function, both of them can be used for thermal insulation, sound proofing and energy-saving. In fact, they have difference in details. First, the raw material is different. Mineral wool uses mineral waste residue as raw material, rock wool use basalt as raw material.

What is ROCKWOOL? ROCKWOOL is a company that manufactures stone wool insulation. Also known as mineral wool, stone wool is created by spinning molten rock and minerals with steel slag to create a cotton-candy-like wool product.

Rockwool is a highly durable insulation option. However, the durability of Rockwool isn't limited to the heat retention quality of the material. The impressive water-resistance, mold-resistance, mildew-resistance, and fire-resistance also contribute to the durability and capability of Rockwool insulation.

However, like many building materials, mineral wool also has its drawbacks. It tends to be more expensive than fiberglass, often between 25-50% higher in cost . Because it is more unusual, it's not available in as wide a range of sizes as fiberglass and is almost never available in a paper-faced format.

It is NON-combustible, NON-corrosive, and odor-free. With the addition of RWPP Wall Adhesive, Rockwool Premium Plus™ Insulation can be sprayed in wall cavities without a net to hold it in the wall.

Mineral wool is commonly used to insulate exterior walls, basements, and heated crawl spaces. It can also be used in continuous insulation applications. Fiberglass is typically used to insulate interior and exterior walls, basements, garages, and attics, but it is not used as continuous exterior insulation.
