Wall material and its ability to withstand heat radiation

Modern home

Using the air conditioner is the biggest monthly expenses include electricity for homes, if we know that there are ways to reduce heat in the house with an alternative way, maybe we can apply it in residences. One way to reduce the heat into the room, is to use appropriate building materials. A variety of building materials has to heat absorption, ie how long the wall material was hot on the inside of the building. For example, in the afternoon, how many hours the wall can withstand heat up to maximum heat into the room.

Surely the wall in question is a wall with a material that is used as a wall, not as a patch alone (exposure). The material described here is a natural stone wall material, concrete, brick and wood walls.

Natural Stone Wall Materials

Natural Stone Wall Materials

The walls of natural stone is one of the most material stores heat radiation, therefore the walls are made of stone cold longer, while other material was hot. Most recommended natural stone wall to the house so much cooler and reduce or even eliminate the use of air conditioning. 30cm-thick walls of natural stone can withstand heat up to a maximum of 8 hours, meaning that the heat from the outside will be retained in the wall for 8 hours before the really hot. Dutch-made houses many ancient walls using natural stone on the bottom of the home, which also serves to hold the heat. Natural stone wall can be an extension of the foundation stone.





Concrete materials

Concrete materials

Concrete walls including a second material that can hold and keep the heat radiation from outside. Because it's concrete wall is also good for us to reduce or eliminate the use of air conditioning. Material 15cm thick concrete walls (normal wall thickness) can withstand heat up to a maximum of 3.8 hours before the walls of the room is really hot.







The stone-brick wall material

The stone-brick wall material

Brick wall is the wall of the most widely used for housing in our country. This wall can also store heat for a long time, where the walls of 10cm can withstand heat up to a maximum of 2.3 hours. Therefore, if exposed to direct sunlight, brick walls will be felt the most heat up to 2.3 hours. Although these materials are less able to store heat when compared with natural stone and concrete, but is most readily available materials and includes the most economical, because it is the most widely used as well.




Materials wood wall

Materials wood wall

Wooden walls are widely used in Kalimantan, Sulawesi, Sumatra, Irian and other outside Java. Readily available wood materials are still a lot of island wood production, as well as a way to build hereditary. Unfortunately this is not the old wood materials in retaining heat, because the timber wall 5cm heat radiation can only hold a maximum of 1.3 hours. Because it is a wooden house should have plenty of ventilation to be cooler. Similarly, when using the AC, will require more electrical power.


Of various materials for walls, it is best to use natural stone walls, but we need to consider also the height of buildings, number of vents, wall height, and so if we do not plan on using the AC. However, given the wall like a rock could damage the natural environment due to take the natural stone of the rivers, it is still advisable to use a brick wall.
