Rockwool batt insulation is also known as mineral wool batt insulation.
Rockwool is a type of thermal and acoustic insulation made from volcanic rock, melted basalt rock, and other minerals that are spun into fibers. This material is then formed into batts.
Rockwool batts typically have a higher density compared to fiberglass batts contributing to their robust insulation and soundproofing properties. Rockwool batts can be used for various applications within residential, commercial or industrial builds. Rockwool batts can be more expensive than fiberglass batts but the benefits in fire resistance and acoustic performance may justify the higher cost.
Rockwool batt insulation is a popular choice due to its excellent thermal and acoustic characteristics, superior fire safety, durability and longevity, resistance to moisture and mold, and eco-friendly properties. Some benefits include:
Rockwool insulation maintains its thermal performance over a wide range of temperatures. Unlike some insulation materials that may degrade or lose effectiveness in extreme temperatures, Rockwool remains stable and effective in both hot and cold environments. Rockwool insulation does not compress or settle over time which helps maintain its thermal performance throughout its lifespan.
Rockwool insulation can be used in combination with other building materials and systems such as fire rated assemblies, vapour barriers, and air barriers, to enhance overall performance. Its ability to control heat transfer and reduce noise makes it versatile for creating comfortable and quiet indoor environments.
Rockwool insulation is designed to fit snugly between framing members, such as studs, joists, and rafters. Its fibrous nature allows it to fill gaps and voids effectively, reducing the potential for air leaks and heat loss. The dense and fibrous structure of Rockwool insulation helps it stay in place and maintain its shape.
Due to their high-density qualities Rockwool insulation is highly affective at absorbing sound waves. The fibers trap and dissipate sound energy reducing the amount of sound that passes through the insulation. In addition to blocking sound it helps to minimize echo and reverberation within a room contributing to better acoustic quality and a more pleasant auditory environment.
The high melting point of Rockwool insulation allows it to act as a formidable barrier to fire, slowing its spread and contributing to overall building safety. Many Rockwool products are classified as non-combustible or have a high fire-resistance rating, making them suitable for use in fire-rated assemblies.
Rockwool contains between 16% to 40% pre-consumer recycled materials. This reduces the demand for virgin materials and minimizes environmental impact. Rockwool does not contain harmful chemicals or formaldehyde and does not release toxic fumes. It can be recycled at the end of its life, repurposed into new insulation products, or used in other applications.
