Using Radiant Barriers

Radiant barrier is a type of heat insulation that looks like a shiny foil sheet. It is often used during construction workUsing Radiant Barriers to reflect heat but can also be installed in the attic of a house to prevent radiation as it works well in closed and narrow spaces.

The attic is the top covering of a house. In hot weather, the attic gets extremely hot and passes the heat to the house. The temperature of the attic and of the house, however, can be controlled by installing radiant barriers sheet. Heat waves flow from hotter region to the cooler region. The radiant barriers work as an obstacle creating it difficult for heat waves to pass through it and enter the house through the roof.  The radiant barriers require airspace in front of them to work.  They may become heat conductor if placed in-between the two pieces of siding. Besides, any dust accumulated on the barrier sheet may reduce its ability to reflect heat.

There are two types of radiant barriers – perforated and non-perforated. The non-perforated can increase the level of moisture and warm air in the house as it doesn’t have any hole to release it outside. The perforated barrier, on the hand, has small holes on it to pass moisture and warm air of the house.

The radiant barriers are a great way to control temperature and humidity in the attic. Here are some of the notable benefits of using a radiant barrier:

  1. The radiant barrier sheet can reduce attic temperature by 30°F as the sheet reflects around 97% of the solar radiation.
  2. Heat travels from hot air to cool air. Radiant barrier cools down the temperature of attic reducing the heat flow to other areas of the house.
  3. The radiant barrier sheet works tremendously well in hotter places. In the scorching heat, the radiant barrier sheet won’t fail but work even more effectively.
  4. The radiant barrier sheet installed in attics may reduce the requirement for AC, significantly.
In short, radiant barriers are a must for homes for its property to reflect heat and prevent radiation from entering the house. It also helps control room humidity.
