Is a fiberglass a conductor or insulator?

Answer 1

Fiberglass and foam board insulation work well because they

interfere with the convective flow essential to that mechanism. The tiny air- or

gas-filled spaces in the insulator frustrate heat flow because they greatly extend the

time necessary for convective and conductive flow to occur. Foe heat to move through such

a material, each cell -- and there are millions -- must relay the heat across it. The

longer it takes, the slower the heat flow.

Answer 2

Fiberglass (at least the stuff that is glass fiber in an epoxy or polyester matrix) is an insulator. I am sure additives of conductors can make it into a conductor though.

Many printed circuit boards are fiberglass just because it is such a good electric insulator.

Answer 3

Fibre glass is not a conductor of electricity.

Answer 4

No. Fiberglass is just like rubber...except breakable. No. Fiberglass is just like rubber...except breakable.

Answer 5

No, fiberglass is not a conductor.

Fiberglass is like rubber but expect it breaks.

Answer 6

Fiberglass is a good insulator. It's often used in home insulation!

Answer 7

If you make it according to the directions on the package, it is.

Answer 8

yes
