If the use effects of mineral wool and glass fiber are the same, then why have I been explaining why I like mineral wool, what are the benefits of mineral wool? Why do I always say: "No, mineral wool is not like this; it is like this"?
This is because the construction community almost universally believes that glass fiber batt insulation is not good. And there are good reasons for us to look, but these, but the more obvious question is, what does this have to do with rock wool boards?
The overwhelming assumption of those interested in building construction is that mineral wool is like glass fiber batts, at least in all aspects they think glass fiber batts are okay. Therefore, if glass fiber insulation is not good, then for the same reason, they believe mineral wool insulation will also be not good. This is an easy conclusion to draw, but it is a lazy misunderstanding. Because not all batts are bad, and the reality is not so. In fact, this just highlights the deep misunderstanding of mineral wool insulation materials by building advocates. The misunderstanding revolves around the form of insulation: batts. When the issues they care about actually revolve around glass fiber batts, the construction community will quickly eliminate such products.
Let's think clearly: is there any problem with insulation in batt form. Batts are a convenient way to package insulation materials for easy transportation, handling and installation, which is why it is the main form of insulation materials. However, there are legitimate reasons to criticize glass fiber batt insulation, namely the current state of American housing construction. This is a short list of reasons, let's look at their differences.
