Insulation
An insulator is something that slows down the rate of heat transfer. The amount of thermal energy escaping from a house can be reduced by using domestic insulation systems that work by reducing the effects of thermal conduction, convection and radiation. Heat insulation can take different forms depending on the type of heat transfer involved. The question arises as to which solid material is good for heat insulation. Non- metals are good heat insulators. Examples of non- metals used as insulators include wood, glass and plastics. Gases are good insulators if you can stop them moving. This prevents them from transferring heat by convection. An example of trapped gases used as insulators is a layer of air trapped by our clothing to keep us warm. The trapped air slows down the rate of heat loss from our bodies by conduction. Materials that trap air can be used in various ways to insulate buildings. . Examples are loft insulation, hot water tank, cavity insulation, double glazing etc.
Why Insulate?
Home insulation costs money, not just to buy the heaters, but also to pay for the fuel that has been used. The amount of fuel we use as a nation each year to keep warm is equivalent to 30 million tons of coal. Better insulation in our homes reduce the amount of energy used to heat homes and reduce energy bills. The government has identified improving households’ energy efficiency as the best way to reduce carbon emissions at the same time as keeping a lid on rising utility bills. According to the renewable energy centre, the average house spends on average: £1230 on fuel bills each year which can be up to 50% more than necessary due to the lack of energy saving measures being implemented in the home.
According to the Energy Saving Trust in an uninsulated home:
Up to 20% heat loss through doors and windows
Up to 25% heat loss through loft/roof space
Up to 33% heat loss through uninsulated walls
