Duck Brand Socket Sealers Variety Pack, 16 Outlet Sealers and 6 Switch Plates, 2 Decorative Covers, White, 283333

They seem to be a perfect option for many reasons with only a single tiny flaw we found.1) They are an affordable option (at least at the moment of writing this) when comparing them to some of the other options out there. They also work just as good if not better in various ways.2) You get a good number of them per box.3) They are indeed flame retardant. This was a HUGE deal when comparing to some of the other options we had laying around. We took a few other options that claimed to be retardant and lit them to find out they lit up like a candle. These ones, however, burned where they got hit by a flame and stopped (no spread). As you can see in the image. We held a flame to it for 4 seconds for that piece in the image. (update: I guess they aren't letting us post the picture for some reason...that makes their policies feel a little shady here)The only flaw? The decorative switch ones (only 4 in each pack) have a gap around the switch itself which prevents it from being a really good seal. It is still enough to make a difference (creating somewhat of a seal), but it isn't perfect in any way. It's a tiny flaw, but if half the pack contained these, this would lower the score. In this situation, we didn't see that as necessary.So, we felt these to be an excellent option for your home for both function and fire safety. You'll feel better at night using these vs some of the other options out there, and your insurance will love you to (god forbid, something happens where they have to even know about them).

I bought these to insulate the electrical sockets on the exterior walls of my house against outdoor temperatures which leak through the sockets, especially with wind. While they do a good job insulating the wind that was seeping in around the electrical box, I'm disappointed to say they *don't* thoroughly block the wind coming in from the sockets themselves. I'm not sure how that happens, but with gusty cold winds, I can definitely feel a light draft when I place my hand over the electrical sockets.On the plus side, these are super easy to install with an electric drill. Just be careful to *not* tighten the plate covers so they're flush with the wall again because you'll break the plate cover around the screw since these do add about 1/16 of an inch to the depth of the outlet. The small gap that creates isn't hugely noticeable unless you're closely inspecting them.The package comes with several different precut insulation pieces for wall sockets and light switches. Most of my light switches on exterior walls are doubles though, so I couldn't use the single light switch insulators provided. Overall, I'm satisfied with the improvement these bring to my home's insulation, especially at the price.

I would give it 5 stars if they included markings for where to cut out for GFCI outlets... how much to cut-off to fit two of these side-by-side for 2-gang boxes... and similar. I'd like to get some foam inserts for the round ceiling light & fan electric boxes, too.Insulation (R-value) is always a trade-off, up-front cost versus ongoing heating/cooling prices, but sealing all the air infiltration is a huge and inexpensive win everyone should strive for. Electrical boxes are the worst and most often overlooked offenders. Just think, if somebody drilled a 2" hole right through your wall, you wouldn't just keep turning up the thermometer, would you??? you'd plug the hole, first.Insulation often gets screwed-up around obstructions, like electrical boxes. I can take the face-plates off of mine, and clearly see huge gaps where the fiberglass bats were cut too short, all because the contractor couldn't be bothered to spend a few more seconds to line everything up, or at least insert some small fiberglass scraps around the holes and gaps he left. So the very small R-value of these inserts is still a huge improvement the over nothing at all you might have. And that goes double if you've blown-in loose fiberglass or cellulose insulation into uninsulated bays with a rented machine, where they have the hardest time filling-in the gaps.I must disagree with other reviewers, and say you'll probably benefit from using these on inside walls as well. Gaps in the framing and/or holes drilled into the walls from the crawl-space, allow air infiltration, unless the contractor did a perfect job with the vapor barrier step, which most do not. I know I clearly get drafts from my inside outlets, though the high winds in the area probably make it more obvious in mine than in most houses. And even if I didn't know I had drafts, sealing all those electrical boxes makes it much harder for bugs (ants, roaches, spiders, etc.) to get into your living space, and only requires me to buy two packs of these inserts, instead of one.

Socket sealer. Say it with me. Socket sealer. Alliteration can be so much fun. Okay, now with that out of our system, down to brass tacks. I love these. They're cheap and easy to install. They block the draft that is sure to come out of an electrical outlet or a light switch. I've used these in apartments and in houses. They work both ways. Just unscrew the plate, slap one of these bad boys in, and screw the plate back in. Just be sure to not touch metal to metal or skin to metal. It's a good idea to flip the breaker to deactivate the outlets you're installing these on. Otherwise you'll give yourself a nice jolt. Or three. You know how everyone tells you not to stick a fork into an outlet? Same principle applies here except your finger is the fork and you can't taste purple for a while. So do yourself the favor of flipping the breaker before installing these. Don't make the same mistake as I did. Once. Or maybe three times. I can't remember too good now.

Each section is perforated and easy to separate and easy to install. Another added protection to the house to help conserve energy. Every little bit helps!
