There are many kinds of radiant barriers and one of them is a foil radiant barrier. The installation is done in homes, mostly in attics. This is done for the purpose of eradicating the effect of the summer heat gain, which plays a part in diminishing the cost of air conditioning expenses. The material used here is highly reflective, which re-emits the effulgence of heat rather than imbibing the hotness. Nevertheless the foil radiant barrier does not accomplish heat conduction such as thermal insulation materials. There are lots of benefits attached to foil radiant barriers and few of these are discussed below.
Foil Radiant Barrier Benefits
Not only does this product promote efficiency in terms of accomplishing the purpose of lower rates, but it is also verily effective for both winters and summers. For the summers it takes the heat away from the home and does not let the outside temperature affect the inside ambiance. As for winter it keeps the warmth of the house secure and safe from the harsh coldness of the outside weather. In terms of cost reduction, there are two dimensions to this benefit.
Not only does it reduce the costs of air conditioning and heating as compared to the regular insulators, the United Department of Energy is also offering tax credits to those consumers who chose to utilize this particular product. As for the regular reduction in energy costs as a result of this particular configuration, one can easily save about 70% to 35% of the actual costs on a monthly basis. This is definitely a productive prospect in this era of recession.
There are three determinants that reflect the level of performance of the foil radiant barrier. The first one is its capacity of emission, which is calculated by the ratio of the effulgent energy (that is left by a surface) to the ratio of a black body, which operates at the same degree of temperature and within the same region. Basically it is something between zero and one and the closer it is to one, the greater the degree of emitted radiation. Then the second factor is the capacity of reflectivity which signifies the measure of heat being reflected by a certain material. The third one is the difference of temperatures on both sides of the barrier (the greater the temperature the better). All in all, these factors are very important in judging the performance of a foil radiant barrier.
