Rock wool is used for lost insulation
It could also be used for sound insulation
Rock wool is a materialused for heat and sound insulation, which is made by blowing steam or air through molten rock. It is wool-like, but does not come from fleece.
no
yes
Glass wool is a thermal insulation that consists of intertwined and flexible glass fibers, which causes it to "package" air, resulting in a low density that can be varied through compression and binder content. the packages of air will not allow conduction to take place
As strange as it may sound dead or still air is one of the best insulators. Insulation such as fiberglass or rock wool and styrofoam work because they are fluffy with trapped air. If you have a sheet of four inch thick R40 fiberglass and squeeze it into a wall made of 2X3 studs you will have less R value than than a 3 inch piece of fiberglass insulation. So the highest R value goes to the insulation that traps the most dead air per inch of thickness and is installed propperly.
Rock wool insulation was a substitute for asbestos insulation. You bought one or the other, not both.

There is no such thing. They have something called rock wool. It's used for insulation.
Insulation, clothing, cleaning up oil spills
Needlework, insulation and manufacture of fabric.
Rock wool is made from natural basalt rock and is denser than fiberglass insulation, making it better at soundproofing and fire resistance. Fiberglass is made from molten glass fibers and is lighter and more flexible, making it easier to handle and install. Fiberglass insulation typically has a higher R-value than rock wool, providing better thermal insulation.
Yes. It is actually used as a firestop or block in buildings.
No. Rockwool or mineral wool insulation is mineral fibers from volcanic rock heated and spun into a cotton candy texture and has never been reported to have been manufactured using asbestos.
Rock wool insulation is typically softer and more flexible than asbestos insulation. Asbestos insulation is denser, heavier, and may have a fibrous texture resembling human hair. It is recommended to have a professional conduct testing to properly identify asbestos-containing materials.
Rockwool and mineral wool insulation materials are both made from natural rock materials, but they have some differences. Rockwool is made from basalt rock, while mineral wool can be made from various types of rock. Rockwool is denser and has a higher melting point, making it more fire-resistant. Mineral wool is generally more flexible and can be easier to install in certain spaces. Both materials provide excellent thermal and sound insulation properties.
The R-value measures the thermal resistance of insulation materials like rock wool. A higher R-value indicates better insulation effectiveness, as it shows how well the material can resist heat flow. In the case of rock wool insulation, a higher R-value means it can better keep heat inside during cold weather and outside during hot weather, making it more energy-efficient and cost-effective for maintaining indoor comfort.
Rock Wool provides insulation products for construction, specializing in "stone wool" technology, which can withstand temperatures up to about 800 degrees Celcius. Products may be used for floors, roofs, walls, etc.
