Rockwool, a popular insulation material, boasts a high R-value, measuring its thermal resistance. It outperforms other insulation types, such as fiberglass, due to its ability to minimize heat flow. Rockwool’s R-value varies depending on application and thickness, providing optimal insulation for different building components like walls, roofs, and attics. Its exceptional thermal performance contributes to energy efficiency, reducing heating and cooling costs while enhancing comfort and reducing noise transmission.
