The radiant barrier is all of the rage for homeowners concerned with keeping their home both comfortable and energy efficient this summer. As most homeowners know, San Antonio’s grueling summers can take their tolls on anyone’s home. This is where the radiant barrier comes in. In addition to great insulation installed by quality, professional experts, a radiant barrier can seriously cut down on the radiant energy the sun transfers to your home. This of course means that a radiant barrier can help keep your home cool in the hot months of San Antonio summer.
Most insulation systems seek to absorb the unconditioned air that inevitably can enter your home. A radiant barrier, on the other hand, will reflect this energy instead of trying to absorb it. This means that your home will not take on as much radiant heat as would a home without a radiant barrier. But how important is keeping out radiant heat? Studies have shown that radiant heat transfer is one of the most effective ways of transferring heat. So, while your freshly installed attic insulation does a great job at trying to absorb radiant heat as it enters your home, a radiant barrier will deflect this heat before it even enters your home.
A radiant barrier could also be a great help during the winter months as well. This is because studies of heat loss in both winter and summer months have shown a great need for the management of radiant heat that can often only be offered by a radiant barrier. In the winter time, 50-75% of heat loss through the ceiling or roofing system and 65-80% of the heat loss through walls is radiant. A radiant barrier can both help keep radiant heat out of your home in the summer, and, in the winter, when you need those extra degrees, it can be a boon to the comfort and warmth of your home. This is why counting your R values alone sometimes is not the best approach, as a radiant barrier can offer you the kind of protection from radiant heat you need in the summer and a radiant barrier can keep that same radiant heat inside the home during the cool winter months. This is why when professional, expert radiant barrier installers diagnose your home needs, they will tell you that a radiant barrier is the best solution for any homeowner to consider.
