About

The idea behind solid wall insulation is to stop heat from transferring through the walls of a building. Heat transfer through the walls can happen two ways: conduction and convection. Conduction happens when heat moves through materials like metal, wood, or glass. Convection happens when air moves over a surface and picks up some of the heat energy before moving on to another surface.
