Insulators or Bad/Poor conductors, thus, are materials that do not allow free and easy flow of ions and electrons from atom to atom. Most non-metals make bad conductors as this easy flow of ions is not possible. Poor Conductors of electricity have a high resistance to electric current.
What is the best lightweight insulating material?
A perfect insulator does not exist because even insulators contain small numbers of mobile charges (charge carriers) which can carry current. In addition, all insulators become electrically conductive when a sufficiently large voltage is applied that the electric field tears electrons away from the atoms.

What is the lowest U-value for walls?
With 50mm of insulation, you can provide a good level of thermal insulation for most applications. To be sure that 50mm is enough, you should calculate the U-value of the entire structure (not just the board in isolation). It is important to reduce cold spots and thermal bridging to get the best insulation value.
What is the U-value of 0.1 wall?
In the walls: Typically, there is not an abundance of space inside your walls, so packing in the insulation isn't a bad idea. To get an R-value of 13 to 16, you will need four to five inches of insulation. However, if you use a more effective type of insulation, you may be able to get away with less.
