Insulation is Basically the slowing down of heat so not as much heat can get to you. But you need something thick like a jacket insulates your body heat.
If something FEELS cold but it has more mass than a match then it has more HEAT than said, match. Because if you have an ice sculpture and you hold a match under it then the match will burn out faster than the ice sculpture. The heat that comes from fire is radiant heat and it travels through the air and warms up a substance or molecules.
Here is the Columbia Space Shuttle and In order to keep the RADIANT heat from the sun from imploding with The heat of the sun.
Conduction is like when you touch the window in your moms car when its really sunny. Convection is when hot air rises or the circulation of air. And Radiant heat is basically the heat of the sun and how it heats up the inside of your body and heats you from the inside out.
Convection is the rise of heat like in a clothes dryer the clothes on the top are hotter than the clothes on bottom or it can be when something hot goes into something cold and warms it up.
