Combat Poor Insulation and Lower Your Energy Bills

If you have areas of your house that are not comfortable or energy bills that are too high, then your current insulation may not be doing enough. Copperflect is a high-performance copper insulation foil that reflects up to 98% of the infrared heat in your home. This means lower utility bills and greater comfort.

How It Works: Summer Through Winter

  1. The 99.99% pure copper reflects up to 98% in both directions, helping to reject heat in the summer and retain heat in the winter.
  2. Copperflect insulates HVAC equipment, allowing for fewer air exchanges to reach target air temperatures, lowering utility bills.
  3. More moderate attic temperatures with higher efficiency heating and cooling mean greater overall comfort in your home.
