Energy-Efficient Vapor Barrier Boxes
• High-strength polycarbonate
construction — will not
shatter when cold or distort
in heat
• V-clamps provide self-
clamping cable entry (multi-
gang and fan/fixture box)
•
1
⁄2" offset flange to ensure
a flush fit in
1
⁄2" drywall
• Angled side nails for rapid
installation
• Pre-drilled flanges for
additional mounting options
Vapor-barrier boxes are designed to meet the energy-efficiency 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. This helps control heating
costs in the winter and cooling costs in the summer.
