Principles of Heat Transfer. Heat is transferred to and from objects -- such as you and your home -- through three processes: conduction, radiation, and convection. Conduction is heat traveling through a solid material. On hot days, heat is conducted into your home through the roof, walls, and windows. Heat-reflecting roofs, insulation, and ...

Within the seal jaws the heating elements are thermally and electrically insulated and supported with a non-stick cover. An impulse of electrical current is passed through the heating element where its resistance develops heat, and passes this heat through to the film layers. This fuses the film layers together, creating a weld. The sealing ...
