Energy-Efficient Vapor Barrier Boxes



Vapor-barrier boxes are designed to meet the energy-efficient requirements of modern homes. They feature a drywall flange covered with a foam gasket and additional gaskets over the cable entry points. These gaskets provide a vapor-tight seal, preventing the free flow of air through the box and helping control heating costs in the winter and cooling costs in the summer.



  • High strength polycarbonate construction-will not shatter when cold or distort in heat

  • Angled side nails for rapid installation
  • Pre-drilled flanges for additonal mounting options
