    Energy costs continue to rise with homeowners and developers requesting that builders use energy efficient products. EnergyLock from Langboard is a value added product where every one is a winner. You increase your profits and the customer saves big bucks on heating and cooling bills.

    EnergyLock is a radiant barrier installed in buildings to reduce summer heat gain and winter heat loss. Tests have shown that radiant barriers reflect 97% of radiant heat. Extensive testing by the US Department of Energy, The Florida Solar Energy Center, Tennessee Valley Authority, and The University of Mississippi confirm that radiant barriers provide significant resistance to heat transfer.

    • EnergyLock prevents up to 97% of the sun’s heat from entering the attic, reducing the attic temperature
