About Lesson
Thermal insulation
- Insulation is used to reduce the flow of heat into an out of the structure by using proper materials of low thermal conductivity.
Functions of thermal insulation:
- It reduces the heat loss from building in winter and cause heat flow into building in summer.
- It keeps the building safe from sudden fluctuation of weather i.e. temperature.
- It saves the fuel cost.
- It controls the condensation.
