What Is Thermal Insulation And Why Is It Important?

Thermal insulation is not simply about keeping out the cold, it is also about maintaining a comfortable ambient temperature indoors and reducing the amount of energy consumed in homes offices and other buildings.

To use the scientific terminology, thermal insulation reduces the transfer of heat between adjacent environments. Having the right amount of insulation and using the right type of material will ensure a good balance between letting heat escape when the temperature is hot outside and keeping it in during cold spells.

If a building is insulated correctly, no matter what the weather is doing externally, the affect on the indoor temperature shouldn’t vary a great deal.

Various kinds of materials are used to insulate houses and offices with most popular material being Fibre glass. Foamed plastic is also used widely, as well as mineral wool, and even cotton slag. There are new materials being trialled all the time with many recycled materials proving to be interesting alternatives.

Aerogel is one insulation technology that is expected to grow rapidly in popularity in the future. The material once formed the basis of insulation for the space shuttle and consists of 95% air. The downside is it currently costs several times more to use this material than others on the market.
