Answer:
There are different kinds of insulation (electrical, thermal, etc.), but I'm assuming you mean thermal insulation.
Insulation should be as thick as practicable because the thicker the insulation is, the less heat loss there is.
Insulation should be as thick as possible since the thickness of the insulation reduces heat loss.
What is an insulator?
Insulators are commonly employed in physics. Insulators are often defined as materials that do not allow electricity to flow through them.
Insulators are also referred to as poor electrical conductors. We may discover various instances of these insulators in our daily lives. Insulators include materials such as paper, glass, rubber, and plastic.
There are other types of insulation (electrical, thermal, etc.), but I'm guessing you're referring about thermal insulation.Insulation should be as thick as possible since the thickness of the insulation reduces heat loss.
Hence,the thickness of the insulation should be as thick as feasible.
