Rockwool pipe insulation: where does it come from and what is it used for?


As incredible as it sounds, rock wool pipe insulation comes from actual rocks. It starts out as basalt or volcanic rock often mixed with steel slag then the mixture gets heated to 1600 degrees Celsius. Older methods involved blowing a stream of air or steam through it. Modern techniques spin the molten mixture on high speed spinning wheels; a lot like making cotton candy. What comes out are fine intertwined fibers. Binders like food grade starch and oil are added to help keep the fibers together and reduce the production of dust. The fibers are collected, compressed into huge mats, then sent through a curing oven. Once through the oven, the machines cut the rock wool into sections and roll it into different diameters.

Rock wool pipe insulation’s most common use is insulating residential pipes against freezing or heat loss. It can also be put to work in the industrial sector by providing heat preservation as well as heat insulation for all sorts of pipelines in electrical power, petroleum, chemical industry, light industry, and metallurgy.

Rock wool pipe insulation comes with many advantages, most prevalent being its resistance to moisture, rot, mildew, and mold along with several types of bacterial growth. Because it repels water, rock wool pipe insulation will never weaken or sag making it ideal for hard to access areas.

There are some small issues to be aware of when installing. Although it does not pose any immediate danger, it may cause temporary itching and discomfort if it comes into direct contact with bare skin, so wear gloves and long sleeves when handling. Rock wool pipe insulation can also release some dust. Be sure and wear proper eye and breathing protection.
