First wrap shiny foil around your bottle to reflect radiant heat. I think bubble wrap is good for the next layer, because it has the most air. Use foam to cover the first 2 layers to prevent heat loss or gain due to conduction. And there you have it, a heat shield!
Insulators are the complete opposite of conductors. Insulators insulate the heat, but conductors let it pass straight through.
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.
the substances that allow heat to pass through them easily are called heat conductors. the substances that do not allow heat to pass through them easily are called heat insulators. ruchi
Materials that do not allow heat to pass are insulators. (In real life, there are no perfect insulators, but if not much heat passes, then it is an insulator.)
Pumice would be among the best. Mica flakes would be good also.

the best insulater would probably be aluminum foil. the reason for this is that it reflects heat and light. That's how solar ovens work.
Insulators are the complete opposite of conductors. Insulators insulate the heat, but conductors let it pass straight through.
Usually nonmetals. Rubber, plastic, wood, cloth, paper, Styrofoam, tinfoil (to reflect the heat.)The most common insulator for electricity is plastic.
The substances that don't conduct heat through them are called as 'insulators of heat'. Eg - Plastic, Wood etc.
Non-metals such as carbon are insulators of heat.
