ROXUL Residential Stone Wool Insulation

The ecological choice for interior walls, ceilings and floors, ROXUL stone wool insulation provides superior fire and water resistance for a safer and more comfortable place to live. Exceptional sound absorption and thermal properties contribute to ambient and acoustic comfort for enhanced recreation and relaxation.


ROXUL insulation provides the comfort you want and the security you need. A fire-resistant insulation, ROXUL resists temperatures of up to 2150◦F (1177◦C) without burning or melting. Non-combustible stone wool does not promote the spread of flame nor produce toxic smoke in the event of fire; these factors may provide critical additional time and protection needed to facilitate an escape.

Water Repellency and Air Quality

Breathe easy with ROXUL. 

Chemically inert, ROXUL will not rot or corrode. An inorganic substance, it will not promote the growth of harmful mold, mildew, or bacteria; these advantages are due in part to its water repellency, fast drying properties and low moisture sorption.

ROXUL SAFE’n’SOUND® is GreenGuard® certified, recognized with its highest indoor air quality designation.
