What is insulation?

---

Insulation is a general term used to describe products that reduce heat loss or heat gain by providing a barrier between areas that are significantly different in temperature. There are several items in the home that benefit from insulation – such as central heating boilers and hot water pipes – however buildings themselves need some extra help to make them more energy efficient. Home insulation therefore reduces the amount of heat that escapes from a building in the winter and protects it from getting too warm in the summer.
