Question:

These two kinds of glass wool are used as insulation materials, but one keeps 0.3 in specific gravity while the other keeps 0.5 in specific gravity. Which one should be chosen?

Answer:

Specific gravity has much to do with quality and thermal conductivity.
It mainly depends on what would you use it for and what temperature of thermal insulation do you need. You can directly look through thermal insulation property of glass wool for further information. If you needs better thermal insulation effect, you can choose heavier specific gravity. If you are not so demanding, you can choose lighter ones.
Generally, materials with high density have better insulation effect, consequently leading a relatively higher price. You can make a layer of polyurethane on the outside. Specific gravity is another way of saying density. Materials' thermal insulation effect is related to density. So if you want to get better thermal insulation effect, you can make a layer of polyurethane on the outside. It is noted that common polyurethane has a maximum temperature of 100 degrees, while high-temperature polyurethane requires 120 degrees.
