ROCKWOOL Insulation Reviews

A look at the vast majority of customer reviews for ROCKWOOL insulation will show that people find it to be an excellent product. Common reviews tout the superior acoustic performance, as well as the increased moisture resistance and R-values in comparison to fiberglass insulation. While most people find the insulation easy and simple to work with, there are those who feel the stones in the non-batt insulation can be sharp and difficult to clean up after installation. It is important to do thorough research both into the product itself and into customer reviews before making any final purchasing decisions.
