Rockwool is a versatile and widely used insulation material known for its excellent thermal and acoustic properties. It is made from natural basalt rock, a volcanic rock, which is melted at high temperatures and then spun into fibers. These fine, durable fibers create a dense and resilient insulation material that is highly effective in preventing heat transfer. Rockwool insulation is commonly used in residential and commercial buildings to enhance energy efficiency by minimizing heat loss or gain. Its ability to withstand high temperatures makes it suitable for applications such as industrial furnaces and fire-resistant barriers.

One of the key advantages of rockwool is its superior fire resistance. Due to its mineral composition and high melting point, rockwool can withstand extremely high temperatures without compromising its structural integrity. This makes it an ideal choice for fireproofing and enhancing the safety of buildings. Additionally, rockwool is resistant to mold, mildew, and pests, contributing to healthier indoor air quality. Its water-repellent properties also prevent moisture absorption, reducing the risk of structural damage and maintaining the insulation’s effectiveness over time.

Rockwool can be used in pizza oven building, but it isn’t ready available in the US, it has lower insulation ratings than ceramic blanket, and it is more difficult to shape, work with and it can be difficult form a smooth dome over its outside edge.
