Why is cardboard a bad insulator?

Cardboard has air pockets between two layers and this slows down the transfer of heat from one side to the other, and any warm air that gets into the air pocket can stay between these layers for a long period of time and maintain its temperature.

It is the air pockets that do the insulating more than anything else, reducing conduction and convection. It has an R value of 0.65-0.7 which is better than cardboard, wool, fiberglass, straw bales, wood, bricks and glass.

What is the best insulator?

The best insulator in the world right now is most probably aerogel, with silica aerogels having thermal conductivities of less than 0.03 W/m*K in atmosphere. of aerogel preventing ice from melting on a hot plate at 80 degrees Celsius! Aerogel has its amazing properties because it’s mostly made out of air.

How do you insulate cardboard boxes?
