Electrical block insulator

EnergyBlock is a piece of foam insulation molded to fit securely around standard electrical boxes, which reduces the chance of mold forming due to moist inside air escaping and condensing on an exterior wall. Electricians can install EnergyBlock in less than two minutes, and it’s sealed after rough wiring is complete so there’s no chance of breaking the seal. The block provides a solid R-10 insulation behind the outlet every time and meets the International Building Code for flame spread and smoke development.
