Rockwool insulation, which is also often referred to as mineral wool or slag wool, is an insulation that is made from a great deal of recycled material. This increases its popularity and makes it preferred for those who are concerned with the various chemicals and unrecyclable material we use in construction.
It's typically found as a loose insulation, so you can stuff it into small areas. Be sure to secure it properly.
One of the greater benefits of Rockwool insulation is that it is naturally resistant to fire. You can use it against heat sources like wood stoves and even chimneys. This is a very rare characteristic of insulation in general.
Most types require you to leave a three to eight inch gap between where the insulation starts and the heat source to prevent potential fire causes. This makes it completely user friendly for those who are looking to insulate wood stoves, pellet stoves, and other sources of natural heat.
If the Rockwool insulation gets wet it will dry on its own and return to its normal condition. Water damages many types of insulation and can be highly problematic for homeowners. This is one of the few that can withstand being exposed to water. You do not want to submerge it for long periods of time, but if it comes in contact with a moderate amount of water, the insulating factor will not be damaged.
It's not the greatest for blocking air. With an R-value of only 2.8 and the potential to use it too lightly, it's not recommended for areas where heavy insulation is needed. It's a lightweight and light duty insulator that can be used in low draft areas, warmer climates and as a filler.
If you're going to install the insulation yourself, you should note that you will need protective clothing. The feeling of the material against the skin is very similar to that of fiberglass. You also want to ensure that you don't install it where there is a returned pattern of air flow.
If the insulation is too close to a return airflow there is the chance that indoor air quality issues will arise. Thus, you don't want it blowing directly into your bedroom. There are simple precautions that you can take to help prevent any potential for air quality problems and installation issues.
While this is not a very expensive type of insulator, it is not found everywhere. Some regions have it while others don't bother to carry it. If you're looking for it and can't find it locally, it's usually best to order it from an online site. This will increase the price a little because of shipping costs, but even so it is still considered to be one of the cheaper insulators on the market.
Rockwool insulation is often used by people who want to do their part to help the planet or those who want to use a lightweight and naturally fire resistant material to fill the space between a heat source and the heavier insulation. It is not often used as a sole source of insulation, but more like a complimentary factor for other insulators.
