Roxul offers an extensive range of stone wool insulation products -- the most fire-resistant category of mineral wool insulation available




Whether you're renovating an existing room, expanding your living space with an addition, or building a brand new home or cottage, choosing the right insulation for the project is extremely important.

 Although insulation will represent only a small fraction of your budget, the choices you make will affect quality of your finished project, and the ongoing costs of your heating and cooling.


Roxul’s advantages make your insulation choice easy.

That's because Roxul insulation goes beyond what most conventional insulations offer. The primary ingredient of Roxul insulation is stone. As a result, it provides some very distinct advantages:


  • Roxul insulation offers a barrier that can delay the spread of fire and provide you and your family with precious extra minutes to escape. Its unique composition won't burn, or release toxic gases or smoke when exposed to high heat. And it can withstand temperatures of up to 2150˚F (1177˚C) – well above heat levels of typical house fires.


  • Roxul insulation actually repels water. As a result, even after exposure to water and moisture, Roxul won't slump in the wall cavity like that of many conventional batt insulation products. Nor does it affect the R-value that Roxul provides. Equally important, Roxul is an inert subtance, and therefore does not support mold or fungal growth , which means a safer indoor environment for your home.

Made from Stone:

  • Roxul insulation is created using a unique combination of stone and recycled slag – a by-product of steel production that would otherwise go to landfill. Its non-directional fiber structure and higher density give it better dimensional stability and make it an effective barrier against noise.

Easy to Cut & Install for Optimal Fit:

  • Roxul stone wool insulation is easy to cut precisely with a serrated blade, such as a bread knife. This allows you to accurately trim the insulation to the wall or ceiling cavity – and get an optimal fit around electrical boxes, wiring, plumbing and ductwork. The result is better R-value and maximum sound absorption.
