Insulation material for piping

[pantheist]

It is noted that the material having high density could be considered as a stronger material in regard with strength, but it is thermally weaker in the other way.Also it is not practical to achieve both parameters (Mechanically stronger and Thermally efficient) in a material.

How less density material is suppose to be called as less thermally efficient?.,Is it because of the composition?Can anyone please clarify the reason behind this?

Yes its the composition. Most insulation works on trapping air or gas in little pockets or bubbles. The bigger the bubbles, the better the insulation, the lower the density, but also lower compressive strength.

Vague question so vague answer.

My motto: Learn something new every day

Also: There's usually a good reason why everyone does it that way

Seriously? Consider that the worst thermal conductor is a vacuum, which has zero structural strength, and literally, zero density.
