Our take on the Universal Foam Outlet Insulation Pads & Seals

These are thin EVA foam pads that sit behind an outlet or switch cover plate to seal the gap between the wall and the plate. Each pad measures about 2.5 by 4 inches and can be trimmed with scissors to fit standard outlets and switch covers. They are a low-cost weatherproofing step for drafty exterior walls, and they work best alongside caulk, door sweeps and insulation rather than as a fix on their own. The pack of 30 covers a whole house's worth of outlets and switches, which is more than most single-room kits offer.

Pros
  • Pack of 30 covers many outlets and switches
  • Trims easily to fit standard plates
  • No wiring work needed; installs behind the cover plate
  • Lightweight foam adds little bulk under the plate
Cons
  • Thin foam only blocks air leaks, not heat transfer through the wall
  • Must be trimmed by hand for a clean fit
  • White foam can show at the plate edges if cut poorly
  • Little effect on its own in a poorly insulated wall

Questions and answers

Do outlet gaskets actually save energy?
They stop air leaking through gaps around outlet and switch boxes, which helps on drafty exterior walls. The savings are modest on their own; they work best with caulk, weatherstripping and insulation.
Will these fit my outlets and switch plates?
The pads are about 2.5 by 4 inches, sized for standard rectangular outlet and switch plates. Trim them with scissors if your plates are smaller or shaped differently.
How do I install them?
Turn off the circuit, remove the cover plate, place the pad over the outlet or switch, and screw the plate back on. No wiring changes are needed.
Can I use them on light switches too?
Yes. The foam trims to fit switch plates as well as outlet plates.
How many do I need for a house?
Count your exterior-wall outlets and switches. The 30-pack usually covers a typical home with spares left over.
