Posted: Nov 27, 2010 |Comments: 0 |

So you have tried all the zany methods to keep out the heat, but none of the processes has worked? You are tired of trying all the possible ways and looking for something worthwhile that really works. If that is the case, then a radiant barrier is the right solution for you. Whether you are a homeowner or a renter, the benefits of installing radiant barrier insulator in your home is priceless. If you are looking for a practical solution to keep away the intense summer heat, radiant insulation barrier is an inevitable tool for you. Installing radiant barrier foil in rooftops and windows will keep away the intense summer heat.


How it works?

The working mechanism of a radiant barrier is simple and need a basic understanding of science. The barrier works by keeping away radiant heat through the mediums that they are applied to. A radiant barrier foil when applied to such a medium reflects away the heat making your room cool. To get the maximum benefit from a radiant barrier, you need to understand the components of heat propagation.



What is heat?

Heat is a source of energy that is usually measured by the temperature of an object.


What is emissivity?

The amount of energy that an object emits at a particular wavelength or energy level is called emissivity. Emissivity varies from object to object depending on its material.

When any object receives energy, it absorbs some energy and reflects the rest.  So a high reflective object will have low emissivity and vice versa.


A radiant barrier has both these properties. An ideal radiant barrier should be highly reflective so that the maximum energy or heat is reflected back. You can install radiant barriers at rooftops so that the heat received will be bounced back and your home will be kept cool. Radiant barrier foils can be also installed on windows and walls to keep away the heat. Investing on radiant barriers is worthwhile, as the foils are durable enough to keep away heat for a long time. Plus, it also helps to cut down your electricity bill. With a properly installed radiant barrier foil, your home can be kept cool naturally even when the outside temperature is rising high.
