Blow-In Rock Wool Insulation | ROCKWOOL

Blow-in rock wool insulation from ROCKWOOL is a highly effective, non-woven mineral fiber solution designed for the thermal and acoustic insulation of existing structures. Unlike rigid boards or batts, this loose-fill material is pumped into cavities, allowing it to conform perfectly to irregular shapes, studs, and joists without gaps or compression. This ensures consistent thermal performance and superior sound absorption throughout the entire insulated volume.

As a retrofit solution, blow-in insulation is ideal for attics, crawl spaces, and wall cavities in older buildings where access is limited or structural modifications are impractical. The material is non-combustible, resistant to mold and mildew, and does not settle over time, providing long-term durability and energy savings. It is an environmentally responsible choice, often manufactured with high recycled content, and safe for indoor air quality when installed correctly.

• Optimal Retrofit Solution: Ideal for insulating existing attics, walls, and floor cavities in older buildings.
• Gap-Filling Capability: Flows into irregular spaces to eliminate thermal bridges and air leaks.
• Non-Combustible & Durable: Class A fire rating, resistant to mold, mildew, and pests.
• Acoustic Performance: Provides excellent noise reduction for residential and commercial spaces.
• Energy Efficiency: Significantly reduces heating and cooling costs by maintaining stable indoor temperatures.
