What is the difference between Rockwool and mineral wool insulation?
Rockwool insulation is usually available in the form of batts or boards. Mineral wool batts are semi-rigid and typically used to insulate interior walls. On the other hand, mineral wool boards are a compressed and rigid insulation product primarily used to insulate exterior walls.
What are the disadvantages of mineral wool insulation?
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 . Because it is more unusual, it's not available in as wide a range of sizes as fiberglass and is almost never available in a paper-faced format.

Can mineral wool insulation get wet?
Although mineral wool is water-resistant, it is not waterproof. Therefore, it is still possible for mineral wool insulation to get wet. If it does become wet, however, the insulation will not absorb the water into its fibers. Instead, it will drain out completely.

There are two kinds of mineral wool available for home insulation – rock wool, which is made from fibers of stone and slag wool, which is fibers made from iron ore waste. The slag and stone mineral wool insulation works as both ...
How does mineral wool reduce noise?
Because it is a porous material, it can also reduce noise in the home by allowing air movement into the fabric. According to MIMA, the fluctuations of the air molecules that form sound waves move into the mineral wool where friction between the air particles and the narrow airways cause that sound to dissipate as heat.
Can you use mineral wool to cover ducts?
A few things to keep in mind is if the mineral wool is added to existing walls with the drywall taken down, you will need to cut the mineral wool to fit around electrical boxes and outlets.

When most people think insulation, they think fiberglass. It is definitely the most common and is widely used in jobsites across the country. Mineral wool insulation is decidedly less common, despite the fact that this insulation has been around for decades, is widely used in Canada and Europe, and is making a comeback in the United States. It is made by melting down basalt stone and recycled slag from steel mills, which is then spun into fiber that can be formed into batts or boards.
What insulation is best for fire?
Mineral wool insulation withstands extreme heat better than other types of insulation. In a fire, the batts retain their shape and offer better protection against flame spread. And you builders may be interested to learn that when they’re combined with special fire-rated sheathing, mineral wool batts can be used to create a one-hour-fire-rated assembly without any extra labor.

Mineral wool insulation batts are denser than other types of insulation, making them better at soundproofing interior walls, floors and ceilings. Install batts between rooms or in the joist spaces between floors to reduce sound transmission.
What insulation batts are good for outlets?
Mineral wool insulation batts are so dense that you can carve them to accurately fit around outlets and other obstacles. Just measure and mark like you would if you were making a drywall cutout. This works for outlets, pipes or any other obstruction you’re likely to run into.
Do mineral wool batts absorb water?
Another cool property of mineral wool batts is that they don’t absorb water, staying intact even when wet. This means that if your wall or roof leaks, the batts will be as good as new after they dry out. Fiberglass or cellulose, on the other hand, droop, clump up or compress when they get wet.
Is fiberglass insulation easy to measure?
It tears, scrunches up and when you try to corral the material it can make you very, very itchy. Mineral wool batts, in contrast, is very easy to measure. It’s rigid form just sits there, unmoving, so you can quickly whip out your tape and get an accurate measurement.

Which is better, mineral wool or glass wool?
If you’re considering installing the insulation yourself, mineral wool is considered much easier to handle. Although heavier than glass wool, mineral wool is much easier to cut, move and fit into place. Glass wool on the other hand is limper, which makes it hard to fit into the spaces required.
What is the R value of glass wool?
R-value. When comparing the two, glass wool has a slightly lower R-value of around 2.2-2.7 compared with 3.0-3.3 of mineral wool, which means it is slightly less effective at preventing heat loss through conduction.
How are raw materials treated?
These raw materials are treated in a similar way to glass, in that they are melted at high temperatures until they melt, and then they are spun to form fibres, similar to wool. This wool is then packaged up into batts, rolls or slabs.
Is mineral wool good for mold?
If you’re looking for a moisture-resistant form of insulation, mineral wool is the clear winner. Mineral wool is resistant to water, so it doesn’t get damp and provide good growing conditions for fungi, mould, mildew or other bacterial growth. Glass wool, on the other hand, can get wet and damp, and as well as promoting the growth of fungi, mildew and rot its insulating properties are severely reduced.
