Radiant barriers can be called also as the reflective, and these are thermal heat insulation types that are inhibiting heat transfer by thermal radiation. Transferring thermal energy can be made possible by the use of the processes either conduction or by convection. However, radiant barriers do not have the capability of protecting against the transfer by convection or by conduction.
There are a lot of definitions being referred to thermal or heat insulation, usually are misinterpreted as a bulk, mass, or batt insulation. These are actually used for resisting the conduction transfer having certain values of R. A radiant barrier reflects the radiation heat, and thus, preventing the transfer from a particular side into another because of a reflective or a low emittance surface.
There are a number of benefits which can be provided by this insulation and one common benefit is reducing a heat radiation from or to a material surface. Even though a barrier is a reflection of a radiant energy, the heat may still not be affected that is conducted through the material. Achieving this can be done by directing a contact transferred by moist air rising or by convection.
This reason has made the association of barriers with R values become inappropriate and much more difficult. An R value will be test measuring a material surface. There have no designed no standard tests in order to measure a radiated energy. A radiated one is an important means of transfer.
However, during nighttime, the phenomenon will still be the same and the radiations will be mathematically described as a linear opposite. Both the directions are being prevented from transferring the radiation through these radiant barriers. However, the flow of heat to and from the surfaces may also occur through a convection which is in different directions based on some geometries.
One most common material that is being utilized as barrier is the reflective aluminum foil. The material does not contain any significant mass of absorption. The E values or emittance values are very low as well, typically having only and amount of 0.03 compared to a bulk type with 0.09. And for this reason, it would be very possible for the reduction of transfer through radiation.
These barriers can be able to provide some helpful advantages and benefits including not having molds and mildews, non carcinogenic or toxic, act as vapor barrier, and effectiveness in warmer clients. Thermal performances will not be changed because of the disintegration, compaction, and moisture absorption. Thin sheets take only much lesser than bulk types. And lastly, radon penetration through the floor is limited.
So therefore, these can be able to provide a superior quality since these are being reinforced for a maximum durability and strength. These have resistance to tear and puncture. The installation is being done easy and in a safe manner which requires no protective clothing or special tools.
However, some disadvantages may possibly be brought as well by these barriers. One is requiring the combination of other insulation types in cold climates. Also, this might probably result to some hazards of the electrical safety in which foil is having a contact with faulty electrical wiring.
