Air-Tight Insulated Electrical Box
Air Infiltration is one of the many problems builders of energy-efficient
homes struggle with on every job. One of the most difficult areas
to stop air infiltration is around and through electrical boxes.
This is caused primarily by the large number of variables in the
insulation installation process. The “Energy Block”
eliminates these variables and gives a consistent and flawless installation
every time. This difficult problem can be completely eliminated
very inexpensively, without the need for additional electrical products
or support. Forget the call-backs and complaints about air leaking
through the outlets, the “Energy Block” makes this a
thing of the past. Besides the increased energy efficiency, the
energy block also greatly reduces the chance of MOLD forming as
a result of moist air leaking to exterior walls, a major concern
in today’s market!
The Solution
A simple, inexpensive
block of foam insulation, molded to fit perfectly around
the electrical boxes. The "Energy Block" is designed to
fit a 2X6 wall, but can be modified to fit a 2X4 wall.
The total installation can be accomplished without
electricians in less than 2 minutes per box. The result
is a near perfect seal around and behind every
electrical box that essentially eliminates air
infiltration. No need worrying about stuffing insulation
behind the box, since the "Energy Block" provides R-10
insulation behind the box. "The 'Energy Block' is molded
from material that is UL
Classified for surface burning characteristics."
Also meets IBC requirements.

Simple Installation
Installs in less than two minutes with repeatable results every
time. Simply apply latex caulk on one side and press to
permanently
secure in place. This will not allow the seal to be broken around the electrical wires when the electrician trims out the boxes. Smooth sealant around the electrical wires and you are ready
to apply insulation. A cutout template is available for perfect
insulation cuts every time. Next, install the precut insulation tightly
around the box. Install poly over the finished insulation
as normal, and cut it out around the electrical box, but overlapping
the "Energy Block". Apply caulk between the poly and the "Energy
Block" and the perfectly sealed installation is complete. You have
just achieved:
- Near Zero Air Infiltration
- Full insulation around and behind the electrical box
- Greatly reduced chance of MOLD forming due to moist inside air escaping and condensing on an exterior wall
