When it comes to insulating residential wall cavities and attic spaces, two of the most common insulation choices are fiberglass and mineral wool batts. While both insulations are excellent choices, understanding the benefits of both materials can be helpful in making the right choice based on the requirements of your building project.

Stone Wool vs. Fiberglass. Both stone wool and fiberglass are popular insulation choices, but they have some key differences: Density: Stone wool is denser than fiberglass, providing better sound insulation. Fire resistance: Stone wool has superior fire resistance compared to fiberglass.

If your insulation project does not involve working with irregular shapes and spaces, Rockwool provides superior insulation for longer. By contrast, fiberglass insulation is much more forgiving and can fill in and insulate spaces where Rockwool cannot.

Home insulation is crucial to keeping your space comfortable and energy-efficient. Among ample options, mineral wool and fiberglass stand out as excellent insulation materials. Here’s a guide that will help you choose between the two better.
