kivivillaa

Kivivillaa, known in English as rock wool, is a mineral wool insulation material produced by melting natural volcanic rocks, typically basalt or diabase, and forming the melt into fibers. The fibers are bound into boards, blankets (batts), or loose-fill products for use in building cavities and other applications. The production process results in a material that is non-combustible and can withstand high temperatures, contributing to fire resistance and safety in structures.

Thermally, kivivillaa provides low thermal conductivity that varies with density and product form, commonly within a range that yields effective insulation in walls, roofs, and floors. Acoustically, it reduces sound transmission and can improve interior comfort. The material is generally resistant to moisture intrusion but is not designed to absorb large amounts of water; performance can decline if it becomes heavily damp, and some formulations include water-repellent features. It does not rot or support common pests.

Common installation forms include batt or blanket products for framed cavities, rigid boards for sheathing or continuous insulation, and loose-fill for retrofit applications. Proper installation is important: cut pieces to fit, avoid gaps, and pair with vapor barriers or ventilation strategies as required by local codes.

Environmentally, kivivillaa involves energy-intensive manufacturing but uses abundant raw materials and can include recycled content. It is typically inert and recyclable at end-of-life. Regulatory standards in many regions require conformity with fire safety, acoustic, and thermal performance standards for building insulation.
