What R-value is Rockwool?
between 3.0 to 3.3 per inch
Rockwool has excellent heat retention.
While fiberglass insulation is capable of offering an R-value of about 2.2 to 2.7 per inch of insulation, Rockwool has an R-value between 3.0 to 3.3 per inch of insulation.
What is the difference between rockwool and fiberglass insulation?
Because Rockwool is denser than fiberglass and has a much higher melting point, it is considered more fire-resistant. Usually, the density of a material is directly correlated with its fire-resistant capabilities, which is why Rockwool batts are widely used as a firestop between the different floors of a house.
What is the R-value of 3 inch rockwool?
3.0 to 3.3 per inch
Rockwool or mineral wool insulation offers an R-value of 3.0 to 3.3 per inch of thickness. While it costs slightly more than other common insulating materials like fiberglass and cellulose, it provides far greater thermal efficiency, heat retention, moisture resistance, and sound-dampening capabilities. What is this?

How thick is R30 rockwool?
How many inches thick is R30 insulation?
What is this? To attain a R30 insulation thickness, a rigid foam board insulation must have 7.5 to 8.33 inches depth.
Which is better R30 or R 13?
The bigger the R value, the better the insulation is at slowing down the heat transfer. So R19 is better insulation than R13, and R30 is better than R19. The larger the R value, the better the insulation value.

Why is rockwool itchy?
Coarse fibers and dust from mineral wool products can cause emporary and reversible irritation (itching, redness) of the skin and eyes. The itching and possible inflammation are a mechanical reaction to dust and coarse fibers (more than about 5 μm in diameter) and are not damaging in the way chemical irritants may be.
