Rock and slag wool insulation offers a wide array of benefits for specifiers, designers, and builders interested in using materials offering environmentally responsible characteristics and demonstrating proven performance.

Outstanding Thermal Performance

Thermal performance is a critical determinant in choosing an insulation product and the product must be thoroughly tested and proven to perform at the same level as when installed for the life of the building. Rock and slag wool insulation is tested at all applicable industry standards to ensure its R-value does not deteriorate over time. Loose-fill rock and slag wool insulation resists settling. The insulation also lends to the sustainable nature of the structure by protecting the building from moisture and fire damage. Further, the higher density of rock and slag wool insulation allows it to achieve higher R-values in a typical wall cavity than most other insulation products.

Excellent Fire Resistance

The performance of building materials in a fire is a key factor in protecting the occupants of the building and allowing them to escape safely. Rock and slag wool insulation is naturally non-combustible and remains so for the life of the product without the addition of harsh and potentially dangerous chemical fire retardants. Because these products have a high melting temperature, they can be used in a wide variety of applications that call for these unique properties. Rock and slag wool insulation is used as a passive fire protection in many buildings. Manufacturers of these products encourage a balanced design, which includes a combination of active, detective, and passive fire protection in building codes to ensure the safety of building occupants.

Excellent Sound Absorption

The fibrous structure and high density of rock and slag wool insulation offer excellent sound absorption properties, making these products an outstanding part of overall wall systems designed to reduce sound transmission.

Mold, Fungi, & Bacteria Resistant

Rock and slag wool insulation resists the growth of mold, fungi, and bacteria because it is inorganic. This product offer enhanced protection against damaging moisture infiltration that can rob insulation of R-value.
