What gives better thermal insulation glass wool or rock wool?

It depends on the application and your budget. The rockwool insulation is more dense (KG/M3) than the glasswool insulation. The rockwool is also economical as compared to glasswool insulation. In some cases where the air velocity is greater one must use rockwool because it does not decay to much and does not cause any health issues. Glasswool and rockwool, both are incombustible so you can choose whatever you want. But I shall go with the economical one.
