Thermal insulation is the process by which a certain combination of materials impede the flow of heat. This combination can be used from different materials.
Different kinds of materials can be used not just for this purpose but also to prevent any kind of damage on these materials that can cause thermal insulation. Heat can be said to be the main product that drives this process.
In a common water flask you can see the perfect example of thermal insulation. Often pipe and duct systems work on the principle of thermal insulation and insulation is built in buildings to maintain a certain temperature.
In an automotive this principle is used to maintain the heat sensitive areas like the batteries.
Thermal Insulation Agents
Substances like glass wool, urethane foam, soil and cellulose act as excellent agents for thermal insulation. The effectiveness of these agents of thermal insulation, can be judged by calculating its R-value or rather what is calculated independent of the environment and other factors.
Since they maintain the temperature of a house therefore people prefer using these materials.
By providing the efficiency of cooling and heating, this process of thermal insulation reduces the amount of energy used and thus saves energy.
Applications of Thermal Insulation
The principle of thermal insulation is very effective in the conservation of energy in our homes. If your ceiling is made of such a material then you can conserve the heat during winter and the coolness during summer.
Cavity wall insulation and insulation boards can come in use for ensuring thermal insulation in and around the house. Since the roof of the house receives the maximum heat therefore heat reflecting paints can really work wonders for the roof of the house.
They will reduce the temperature by deflecting the harmful UV rays that fall directly on the roof. Foam insulation within the walls of the house also cause thermal insulation. Insulation can be of various kinds from acoustic insulation to electric insulation. What you use in your home for insulation might depend on various factors like cost and climate.
If the walls of the house are yet to be renovated or finished, then you should use fibreglass as your insulator. For major works of renovation vermiculite is an excellent material though they might require masonry.
Loose fill cellulose are good for attics and ceilings that have not been completed.
