Stone Wool Insulation

Start your project with ROXUL® — the fire-resistant insulation that’s made from stone. Home owners, contractors and builders rely on ROXUL for no-compromise insulation solutions that help save energy and create quiet and safer homes. Although insulation will represent only a small fraction of a construction budget, the choice of insulation will affect the quality of the finished project and the ongoing costs of heating and cooling the home. Additionally, the decision will have an impact on the environment.

ROXUL’s line of fire-resistant insulation for residential use includes both thermal and soundproofing products: ROXUL COMFORTBATT® and ROXUL SAFE’n’SOUND® ROXUL SAFE’n’SOUND® is GreenGuard® certified, recognized with its highest indoor air quality designation.

The advantages of ROXUL make your insulation choice easy.

ROXUL insulation goes beyond what most conventional insulations offer. The main ingredient of ROXUL insulation is stone. As a result, it provides some very distinct advantages:

Fire Resistant:

  • 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.
  • Won’t burn, or release toxic gases or smoke when exposed to high heat.
  • Withstands temperatures of up to 2150˚F (1177˚C) – well above heat levels of typical house fires.
  • 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 Repellant:

  • After exposure to water and moisture, won’t slump in the wall cavity like many conventional batt insulation products and R-value will not be affected.
  • 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.

Made from Stone:

  • Created from a unique combination of stone and recycled slag – a by-product of steel production that would otherwise go to landfill.
  • Non-directional fiber structure and higher density for better dimensional stability and an effective barrier against noise.

Easy to Install:

  • Easy to cut precisely with a serrated blade, such as a bread knife.

Sound Absorbent:

  • Non-directional fiber of ROXUL stone wool helps absorb acoustic waves and can reduce the intensity and propagation of noise.
  • Effectively reduces airflow and sound transmissions.
  • Higher air flow resistivity means better sound attenuation.
