Mineral Wool

ROXUL COMFORTBATT® is a stone wool insulation product for use in both new residential construction and renovations. This semi-rigid batt has a unique flexible edge designed to compress as the batt is inserted into walls, attics, ceilings and floor frames. The flexible edge springs back, expanding the batt against the frame studs to give a complete fill. ROXUL COMFORTBATT® compensates for normal variations in stud centres caused by distortion or warping. The special flexible characteristic at the insulation edge ensures the expected R-value is achieved. Stone wool was discovered on the islands of Hawaii at the beginning of the century. It occurs there naturally as a byproduct of volcanic activity.

Applications:
This product is specifically engineered for use in exterior walls, cathedral ceilings, attics, basement walls, exposed floors, and heated crawl spaces.

Sound-Absorbent

  • Unique non-directional structure of ROXUL stone wool insulation content is denser than traditional insulations
  • Effectively reduces airflow and sound transmissions
  • Higher air flow resistivity means better sound attenuation

Sound Absorption

  • Non-directional fiber of ROXUL stone wool helps absorb acoustic waves and can reduce the intensity and propagation of noise

Fire Resistant

  • ROXUL stone wool can withstand temperatures up to 2150º F (1177º C);consequently it does not contribute either to the development and spread of fire or the release of toxic gases

Water Repellent

  • Water repellent yet vapour permeable
  • R-value unaffected by moisture
  • Completely resistant to rot, mildew, mould and bacterial growth- contributing to a safer indoor environment

Dimensional stability

  • Retains its characteristics over time
  • Minimal changes in size and performance are evident with changes in temperature and humidity
