In the summer, the heat from the roof emits down through the attic into the living space. When Copperflect radiant barrier is installed in the attic, the infrared heat is reflected out before it can penetrate any further, reducing the temperature of the attic by as much as 30 degrees F.
With the attic cooler, the insulation below won’t have to work as hard because it will be under a lighter load, and the A/C doesn’t have to work as hard and won’t have to cycle on as often to maintain the lower temperature.
Copperflect radiant barrier works best in the summer, but it also helps during the winter. The heat generated inside the living space needs to be prevented from escaping, especially at night when the temperatures drop the most.
As heat conducts to the drywall and attic insulation, the mass of those objects store and re-emit the heat in the form of infrared energy. Copperflect is the best solution because only a copper radiant barrier can reflect 97% of the infrared heat without losing its reflectivity over time.
