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.

Give some examples of materials that slow heat transfer?

Does glass have a higher thermal conductivity than wood?
Depending on the glass, it has a K value between 0.8 and 1.1 Wood has a K value of between 0.04 and 0.4 The higher the K value the better the thermal conductivity. Thus glass has a higher thermal conductivity than wood.
Why is plastic used in loft insulation?
Plastic. fiberglass. ceramic. cork, eider down is not the insulation... the insulation is the dead air in the small cells plastic is combustible, glass is not fiberglass is a better choice for habitable areas
What keeps the contents of a thermos flask hot or cold?
The thermal insulation used round the container holding the food. This is normally an evacuated, mirrored, double walled glass flask with an insulated stopper.
What does glass do with heat?
Glass does not "do" anything with heat. Glass is not a (thermal) insulator though.
What is glass wool soaked in water?
Wet thermal insulation.
What is a type of insulation?
There is more than one kind of insulation, the main types being thermal and electrical. Fiber glass is commonly used for thermal insulation, and rubber is a good electrical insulator.
Why does the glass on a window pane feel cooler to the touch than the wood frame surrounding the glass?
Wood is a better thermal insulator than glass, which is easily cooled.
Why is glass wool used for insulation?
Glass wool is a thermal insulation that consists of intertwined and flexible glass fibers, which causes it to "package" air, resulting in a low density that can be varied through compression and binder content. the packages of air will not allow conduction to take place

Is it ok to put new fiber glass insulation over old vermiculite insulation?
Yes, it is fine to do that. You should also put the batts perpendicular to the rafters. This will help tp minmize thermal bridging.
Is a thermal carafe coffee maker better than a glass carafe one?
A glass carafe is better to use. In a glass carafe you can see how much coffee is left and is much easier to clean.
Are good thermal insulators good electrical insulators too?
no A2: Not necessarily. Solid plastics or solid glass or ceramic have high dielectric strength but not good thermal insulation. Closed-cell foam has good thermal insulating properties but not as good a dielectric strength as solid--there are pockets of gas or air in it. The D.S. is not much better than using the same volume of gas, alone.
Does glass have a higher thermal conductivity than wood?

Is a glass vacuum thermos vacuum better than a stainless steel vacuum?
Theoretically yes because glass is a poorer thermal conductor than steel.
What is house insulation made of?
Shreds of glass called fiber glass
