wool is a better insulation than sand
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.

I think it would be wool but I am not 100% sure.
one is made from rock and one is made from fibre glass

The most commonly used insulation is glass wool. this is made from sand which is melted and spun into glass fibres.
Rock wool is used for lost insulation It could also be used for sound insulation
Heat insulation would be wool. Note that denim is normally made of cotton, or a cotton/polyester blend. None of them would be very good electrical insulation when wet.

Rock wool insulation was a substitute for asbestos insulation. You bought one or the other, not both.
Answer nr. 2 Contrary to the logic expressed in the first answer, packing more tightly, glass wool would insulate slightly better, According to Izi, (sales person at Golmat ltd.). Doubling the thickness of glass wool insulation will double the insulating ratio, while doubling the density will increase the insulation ratio by about 15%. Mic602 most likely decrease. most insulation materials are based on trapping air which is a great insulator, by compressing them you would be pussing the air out and reducing insulation value.
Wet thermal insulation.
no
Clothing including jumpers, cardigans, suits and wool insulation for keeping houses' warming
Does Red Top Insulation Wool contain Asbestus
Mostly good heat insulation properties.
Insulation, clothing, cleaning up oil spills
