ROXUL Mineral Wool Insulation
Sound Absorption
The non-directional fiber orientation of the stone wool helps the absorption of acoustic waves and can reduce the intensity and propagation of noise.

Fire Resistant
Mineral Wool Insulation can withstand temperatures up to 2150º F (1177º C). Consequently, it does not contribute to either the development and spread of fire or to the release of toxic gases.

Water Repellent
Mineral Wool Insulation is water-repellent yet vapor permeable. This means that the insulation cannot absorb water so the R-value is not affected. Additionally, it is completely resistant to rot, mildew, mold and bacterial growth, contributing to a safer indoor environment.

Dimensional stability
Stone wool retains unaltered characteristics over time. It undergoes only minimal changes in size or performance, in relation to the changing conditions of temperature and humidity.

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

There's a reason Roxul insulation products are frequently specified for the most demanding applications. They offer a unique set of benefits not found in most conventional insulations. (Access technical information on specific products using links above.)
Stone wool, also known as Mineral Wool, was discovered on the islands of Hawaii at the beginning of the century. It occurs there naturally as a byproduct of volcanic activity. In its manufactured state, stone wool combines the power of rock with the characteristics of typical insulation wool. In addition, thanks to its non-directional fiber orientation, it also exhibits some unique and valuable characteristics.

Stone wool is an excellent insulator and a vital component of an energy-efficient building. In fact, insulation saves 12 times as much energy per pound in its first year in place as the energy used to produce it.
