With hot summer season hitting its high peaks, air conditioners often work overtime. Marcus Hiles reasons that the excessive energy usage occurs because of the traditional roofing insulations in most buildings. A roof soaks up the sun’s radiant energy, heating up the attic and air pipes, which then increases cooling costs. This, however, can be averted if you use highly reflective roofing barrier panels, which block radiant heat. Installed in the attic, they reflect the heat and can block up to 97 percent of heat emission from the underside of the roof. Hiles notes that this third trick will help you cool down your attic by 30 degrees.
