4. Insulation properties

The qualities of a good insulator are :

• good resistance to heat transmission;

• good mechanical strength ;

• a very wide temperature range ;

• good resistance to operating temperatures;

• be non-flammable;

• be chemically neutral (non-corrosive);

• be resistant to external aggressions (humidity, rodents, etc.);

• low specific mass to avoid overloading the systems;

• low implementation costs.

However, no single insulator has all these properties. Depending on the goals and constraints of the insulation project, you need to select the insulation with the...
