Radiant barriers are also called as a reflective insulation. These are types of a thermal heat insulation that inhibits the transfer of heat through a thermal radiation. The thermal energy can be transferred as well through the process of convection or through conduction. However, these radiant barriers may not be able to protect against transfer through convection or conduction.
There are many different definitions that are referred to a thermal or a heat insulation, are usually misinterpreted as mass, batt, or bulk insulation. The purpose of these is actually to resist a conduction transfer with some certain R values. The radiant barrier or the reflective insulation will reflect radiation heat that can help to prevent transfer from one side to another due to low emittance or reflective surface.
There are many benefits that are being provided by insulation. The most common benefit is reducing heat radiation in either direction of material surfaces. Though this barrier serves as reflection for radiant energy, heat which is conducted by the material cannot still be affected. And in order for this to be achieved, the transferred contact must be directed through moist air rising or convection.
Because of this, associating the R values with the barriers can be difficult and can also be inappropriate. The value of the R will test measure the transfer the surface of a material. There are no standard tests being designed for measuring the reflection of the radiated energy. This radiated is the significant means of transfer.
However, at nighttime, there will still be a similar phenomenon and radiations are being described mathematically as linear opposite. The two directions have been prevented on transferring radiation by the radiant barriers. But the heat flow from and to the surfaces may possibly occur through convection having different directions according to some geometries.
Reflective aluminum foils are the most commonly used materials utilized as barrier. These materials do not have significant mass which may be necessary for absorption. E or emittance values are also low, and typically, the amount would only be 0.03 than the bulk type having 0.09. Because of this, transfer reduction by radiation could be more advantage.
The advantages of these barriers would include being effective for warmer climates, may act as vapor barriers, non toxic or non carcinogenic, and do not mildew or mold. Another is there will be no changes in thermal performance because of disintegration, moisture absorption, and compaction. The thin sheets may only take up a lesser compared to the bulk type, and lastly, will limit the penetration of radon through floors.
And therefore, these will surely provide superior quality it is because the reinforcement has been done for maximum strength and durability. These are also resistant to puncture and tear. Installing them can be done safe and easy, requiring no special tools and as well as protective clothing.
But in spite of these advantages, these can possibly bring some common disadvantages as well. One is these would require combining with other types of insulation for cold climates. This might also possibly result on having electrical safety hazards wherein foils are in contact with a faulty electrical wiring.
