Heat Insulation in Buildings.
What is an Insulator and what are U-values?
Something that slows down the rate
of heat transfer
is called an insulator.
for buildings are given U-values.
The lower the U-value, the better the material is as an insulator.
The word "insulator" is also used in
for a material which does not conduct.
insulation can take different forms
depending on the type of heat transfer involved.
We shall look at examples of heat insulation in buildings involving
Conduction Convection Radiation
