How do insulators reduce heat loss

Heat escape routes. Take a look at this thermogram of a house. The roof and windows are the hottest, showing that most heat is lost from the house through those parts. Heat energy is transferred from homes by conduction through the walls, floor, roof and windows. It is also transferred from homes by convection. For example, as hot air in rooms rise, cold air can enter the house through gaps in doors and windows to replace it.

This stops the movement of air in the space between the two layers of glass and reduces heat loss from the window. Science is based on and derived from observations of the world around us from which interpretations are made. Scientists depend on empirical evidence to produce scientific knowledge.

For example, cold air can enter the house through gaps in doors and windows, and convection currents can transfer heat energy in the loft to the roof tiles. Heat energy also leaves the house by radiation - through the walls, roof and windows. There are several different ways to reduce heat loss:.
