Heat Transfer Through Windows occurs by Conduction, Convection And Radiation

Our task, if we want to be energy efficient, is to cut down on heat transfer through windows. There are three ways that heat transfer occurs: Conduction, Convection and Radiation. Window engineers use the physics knowledge of heat transfer to develop window technology that cuts down on heat transfer. Dr Peff Puff and Heat Team A sent us a site that has great windows for sale that cut down on all three types of heat transfer. They use the heavy gas Argon instead of air in the window cavity. This cuts down on convection. They have a special low e coating that reflects heat back into the house but allows heat pass in from the sun. They have spacial insulated spacers that cut down on conduction of heat through the frame.
