Similar to rockwool, once fiberglass is installed it will begin to settle, which will cause it to leave a gap of air on top of it that lets sound and heat through. is a popular and efficient choice for thermal insulation. Thanks to its durability, safety profile, and good thermal properties, fiberglass is going into a wide range of industries and products. Rockwool Insulation For Soundproofing - All The Facts! A normal R-value for Rockwool is between 3 and 3 1/3 per inch, whereas a typical R-value for fiberglass is between 2 1/5 and 2 7/10 per inch .
