comfortable throughout the seasons. While rock wool dominated the U.S. insulation market through the 1970s,
fiberglass has since become the most widely used insulating material in the U.S. As you shop for insulation,
consider factors such as price, thermal properties and fire resistance to find the best insulation for your home.

Broad Fiberglass is made from very fine strands of woven glass, which are formed into rolls or blankets
that fit within wall cavities. This material also comes in a loose-fill form, which can be piled on the floor in an
attic or blown into wall cavities. Rock wool features a similar form, with both rolled blankets and loose-fill
products available, but this material is made using strands of heated rock or minerals instead of glass.
While the average fiberglass insulation product contains 20 to 30 percent recycled content, according to
the U.S. Department of Energy, rock wool consists of 75 percent recycled content or greater, making it
a more eco-friendly choice for those concerned about recycling.
Fire Resistance
Broad Rock wool offers a higher density than fiberglass, which helps to improve fire resistance. Rock wool
can withstand temperatures up to 1,800 degrees Fahrenheit, while fiberglass melts at around 1,100 degrees
Fahrenheit, according to "The Solar House -- Passive Heating and Cooling." This higher melting point makes
rock wool more effective than fiberglass at slowing the spread of flames during a fire.
Sound Attenuation
While both fiberglass and rock wool can help block noise, rock wool's greater density and weight make it
a slightly better sound blocker than fiberglass. The DOE reports the density of fiberglass insulation at 0.5 to
1.0 pounds per cubic foot, compared to 1.7 pounds per cubic foot for rock wool. This higher density allows
rock wool to reduce sound transmission through a wall by around 10 decibels, while fiberglass insulation
reduces sound transmission by as few as 4 decibels, or as many as 10, depending on the material and
how it is installed.
