UNSPSC 11151519: Rock wool or mineral wool

A fiber made from natural or synthetic minerals or metal oxides heated to molten rock at a temperature of about 1600 degrees centigrade, through which a stream of air or steam is blown.

UNSPSC 11151519 Rock wool or mineral wool is a Commodity code that describes insulation materials commonly used in building construction, HVAC systems, and industrial applications. State and local governments purchase rock wool and mineral wool products primarily for facility maintenance, renovation, and new construction projects where thermal or acoustic insulation is required. The code sees procurement activity from county purchasing departments, municipalities, school districts, and cooperative purchasing vehicles that aggregate demand across multiple jurisdictions and public entities.

The most recent opportunities tagged under this code do not reflect substantive rock wool or mineral wool procurement. A Williamson County, Texas notice (26OTHER73, posted July 2026) announces a departmental relocation with no procurement scope. A Sourcewell cooperative purchasing RFP (061626, posted May 2026, due June 16, 2026) seeks law enforcement equipment—a category unrelated to insulation materials. No recent state or local solicitations in the source document specify rock wool or mineral wool as the primary procurement target, indicating limited current activity under this code in the tracked opportunities pool.
