Using rockwool insulation has become less popular over the years for several reasons. If you're trying to decide whether this is right for you or not, here are some of the reasons why many homeowners and contractors prefer not to use rockwool insulation.
The main reason that rockwool insulation is so widely frowned upon is the mineral wool from which it's made. Many compare it to asbestos and they are scared to use it. Even if you feel comfortable using it, you may want to consider whether you are ever going to sell your home, as you may have a hard time finding a buyer with this type of insulation in it, and the negative image it has.
Irritation is another big reason why this particular type of insulation is not widely recommended. If you are the one installing it or are even near it, you may find that it irritates your skin, nose, and eyes which can be dangerous in any way you look at it.
Be sure that you are weighing the pros and cons of rockwool insulation before you decide whether or not to use it in your home. Keep in mind that there are many other options from which to choose when it comes to insulation.
