Why would you choose to insulate your loft, and replace your windows with double glazing?

To save the environment and reduce your electricity bills
it is essential to adopt methods that reduce the consumption of
electricity.

Heating homes in winter uses a large amount of
electricity. One of the reasons behind this is that only a small percentage of the heat
generated by the heaters actually raises the temperature of the house. The rest escapes
from the house to the outer atmosphere.

Heat rises upwards
and escapes from the tiles that make up the roof very easily. One way to deal with this
is to insulate the loft. In addition, normal windows allow infra-red radiation to escape
easily. Double glazed windows on the other hand are made up of two glass panes with a
small amount of gas sealed between them. These are very efficient in stopping the
passage of heat through them.

By insulating the loft up to
15-20% of energy usage can be decreased. Using double glazed glass for windows reduces
energy usage by 20-30%.
