i think it is due to them having air spaces so it takes longer for heat to escape

What are good insulators?
Good insulators include glass, styrofoam, plastic, wood, rubber, cloth, air, glass, and etc. It really depends on what you want to use it for. For example, fiberglass or styrofoam works the best as heat insulators. And rubber or glass as electric insulators.
What are three good insulators of heat?
Three good insulators of heat are, maybe plastic, wood and glass! That's all I can think of right now but plastic and wood are very good insulators (etc. used of saucepan handles)
Is fiber obtics a good conductor of electricity?
No. An optical fiber is a slim hair composed of glass. Glass is a fine insulator, and an optical fiber doesn't conduct electricity at all.
Name 3 good insulators of electricity?
plastic, glass, and rubber_porcelain, wood, and yeah rubber
What are good insulator and bad insulator?
some good insulators are glass styrofoam and almost anything that does not conduct heat very well
Why are foam and air good insulators?
it is
3 examples of thermal insulators?
Expanded polystyrene (packing foam) is generally considered a good heat insulator. Aerogel is considered to be one of the best insultators: You can place a Bunsen burner flame on one side of a thin slice of aerogel and your hand on the other side and not get burned.
What substances are the best insulators?
Usually nonmetals. Rubber, plastic, wood, cloth, paper, Styrofoam, tinfoil (to reflect the heat.)The most common insulator for electricity is plastic.

Are glass and wood good insulators?
Yes they r
What are 2 good insulators of heat?
glass rubber
What are for good electrical insulators?
Rubber, Glass, Plastic, Porcelain, etc.
Are good thermal insulators good electrical insulators too?
no A2: Not necessarily. Solid plastics or solid glass or ceramic have high dielectric strength but not good thermal insulation. Closed-cell foam has good thermal insulating properties but not as good a dielectric strength as solid--there are pockets of gas or air in it. The D.S. is not much better than using the same volume of gas, alone.

Make a sentence with the word fiber glass?
Fiber glass is a synthetic building material. It is really made of glass, but is processed in such a way as to be strong, light weight, and durable.My tennis raquet is made of fiber glass. Speed boats made of fiber glass really go fast. Fiber glass makes good insulation.
What are good examples of heat insulators?
vacuum, styrofoam, plastic, wood, glass, rubber
Is fiber glass a good shock absorber?
Yes it is.
