Rockwool can withstand temperatures of up to 1000° C (1800° F), while fiberglass melts around 600° C (1100° F). Glasswool is more versatile & cost-effective at lower weights whereas Rockwool is 10% thicker to give the same performance. This makes Rockwool a little better at insulating than fiberglass.

What kind of insulation is rock wool made of?

It’s called rock-wool insulation. What Is Rock Wool Insulation? Rock wool, which is also called mineral wool, comes in easy-to-install batts, similar to fiberglass. But instead of being composed of fluffy glass fibers, rock wool is made of—you guessed it—rocks, which doesn’t even seem possible.

Where does the Rockwool mineral wool come from?

The recycled content in mineral wool is derived from the steel slag. ROCKWOOL products contain between 16% or 40% pre-consumer recycled material dependent on the ROCKWOOL manufacturing facility location.

Is it safe to use Rockwool for insulation?

Made of natural materials, rockwool insulation is safe to manufacture and use, when proper guidelines are followed. Decades of research have shown that it poses little to no health risk to humans, including that of respiratory and other cancers. Is Amazon actually giving you the best price? This little known plugin reveals the answer.

What’s the difference between slag wool and rockwool?

Stonewool is made from volcanic rock (dolomite, diabase and basalt), which is not a recycled material, but is an abundant resource. Slag wool is made from the recycled waste product of a blast furnace. Stonewool gives a higher quality and performing product than Slag wool, even though the two are often referred to as Rockwool.

Is mineral wool an irritant?

Coarse fibers and dust from mineral wool products can cause emporary and reversible irritation (itching, redness) of the skin and eyes. The itching and possible inflammation are a mechanical reaction to dust and coarse fibers (more than about 5 μm in diameter) and are not damaging in the way chemical irritants may be.

Is Rockwool cancerous?

The EPA has classified refractory ceramic fibers as probable human carcinogens. The International Agency for Research on Cancer (IARC) has determined glass filaments, glass wool, rock wool, and slag wool to not be classifiable as to their carcinogenicity to humans (Group 3).

Is mineral wool cancerous?

The World Health Organizations’ International Agency for the Research on Cancer (IARC) considers Mineral Wool insulation fibres as not classifiable for cancer in humans.

Is mineral wool safer than fiberglass?

While, both unfaced fiberglass and unfaced mineral wool are noncombustible and help delay the spread of fire, mineral wool does have a much higher melting point than fiberglass, and as such it is often considered the more fire-resistant material.

Is mineral wool expensive?

Mineral wool is also very fire resistant and can act as a fire stop. However, like many building materials, mineral wool also has its drawbacks. It tends to be more expensive than fiberglass, often between 25-50% higher in cost .
