To create a barrier that will reduce cooling costs a highly reflective material is used that will reflect instead of absorbing it. These barriers are installed in attics. In general, the attic is cold in winter and a sauna during the summer.The sun’s energy radiates through the roofing materials to the attic. Without the proper attic radiation barrier, the heat will transfer from underneath the roof slowly to the attic; which results in the attic becoming completely heated and so is the home.An attic radiation barrier creates a proper balance that reduces the transfer significantly. The result is a comfortable home temperature and manageable electric bill.
