Have you ever felt that the house feels very hot during the summer and too cold in the cold weather? This can happen because your house does not have insulation. Insulation can keep the temperature in the house stable and help save electricity use in the summer because there is no need to turn on the air conditioner. In addition, insulation can also keep the house warm enough during cold weather. So, what is insulation and how to use it at home?

Insulation is a coating that can help to keep the temperature in the house stable or comfortable throughout the year and protect the house from cold and hot weather. Insulation is also useful in reducing noise pollution. A properly insulated house can save energy use as well as electricity costs. Insulation can applied to roofs, floors, walls, or windows and doors. However, the walls are the most important to insulated.

To understand how insulation works, there are three basic mechanisms related to heat flow, they are conduction, convection, and radiation. Conduction is the way heat moving through an object such as a spoon in a hot cup of coffee can transfer the heat to the handle of the spoon. Convection is the way heat circulates through liquids and gases. This is why lighter and warmer air rises, while cooler, denser air descends. Radiation, on the other hand, is heat moving in straight lines and heating up anything solid in its path, which absorbs its energy. Regardless of the mechanism, heat flows from the hotter area to cooler area until there is no longer temperature difference.

Insulation is made of different materials and qualities, but generally good insulation consists of a product with structure similar to wool. Fabrics like cotton and flax are also good insulating materials. Thus, having curtains with this material can help insulate the house properly. Then, wooden doors. This can help keep the house warm.

Types of home insulation as mentioned above, can installed at several points in the house as below:
Wall
For the cavity wall, the insulation material will inserted into the wall through the drilled hole, then covered again with cement. There are also solid walls that can sheathed with internal or external insulation. For external insulation, the insulation material will usually cover the entire facade of the property. Internal insulation has applied indoors.

Roof
For the roof area, there are types of insulation that can installed, they are right under the roof (roof insulation) or right above the house ceiling (ceiling insulation). Usually, roof insulation is the better type.

Windows and doors
Insulation of windows and doors done by installing double-glazed windows on a single frame. It is not only able to help the house choose a stable temperature, but also protects the house from noise.

Floor
Floor insulation is quite expensive. Usually, modern homes have insulation under the concrete floor surface. Alternatively, you can use carpet on the floor.
