All AIRFOIL® products use the same sealing chamber and knockout system to create a visible, airtight seal around electrical wires, cables, and phone lines that effectively prevents the infiltration of air and moisture. Each design has a 1 1/8 inch flange around its perimeter, making it very easy to establish the seal between box and drywall or vapor barrier.

To seal the wiring in place, just fill the upper and lower cavities with low expansion foam. Click on the thumbnail pictures above for installation and sealing instructions.

AIRFOIL, INC has developed a line of airtight electrical outlet and device boxes that play a fundamental role in energy efficient home construction. The AIRFOIL® product design is the result of over 20 years of experience in building energy-efficient homes by Minnesota builder and super insulation pioneer Doug McEvers. They're easy to install, and once sealed, they stop air infiltration at the electrical opening every time. 

For full box customers: 24 pieces per box

AIRFOIL® products are made in Doug's home state of Minnesota USA.
