materials such as fibreglass are good insulators because they contain pockets of trapped air. :)
Air is an excellent insulator. Fiberglass is a good insulator because of the vast amount of air spaces trapped in it.
Fiberglass is a good insulator. It's often used in home insulation!
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.
it is good heat insulator, as it has air in it. as air is a good insulator of heat, the sponge, which has lots of pockets of air also becomes a good insulator
It is a good insulator of heat :)

a good insulator of heat keeps the heat in, so you stay warm
A: Glass is a very good insulator and fiber glass are just fibers of glass. VERY dangerous if inhaled because of it.

insulator is a object that is not a good conductorSo it keeps the heat in.

A good insulator is good at stopping heat escaping, whereas a bad insulator is not very good at trapping heat and lets it out.
