Your cart is empty. Letting cold drafts sneak through your door frames can affect the power output of your HVAC.
Some doors sit perfectly against their frames but still manage to let air and debris pass freely. Unfortunately, come winter or summertime, this can cause your electricity bills to spike. While you may think it's just a bit of extra dust to clean up, it's like keeping your window open. Everyone knows that leaving even just the tiniest gap can let air escape, messing with your indoor temperature.

The lower corners of my back, front and garage door had gaps that was letting air out and bugs in. Once these were installed the performance of my AC improved (surprisingly) and no bugs. I don’t know why i waited so long to fix this problem with such a simple fix

Once it’s on, it stays on.PROS: • Easy installation. Just peel, stick, and let your doorframe experience its personal makeover. • The 4-pack is perfect for all your door needs, front, back, side door, basement…you get the idea. You’ll feel like you’ve got the whole fortress sealed up. • Keeps drafts out, which means fewer cold spots in the house and more money in your heating bill fund. • The sleek black color blends into the doorframe like it was always meant to be there.

They do just exactly what they say they would do in the description. Very easy to apply doesn't interfere with the way your door closes in fact it makes it seal tighter. I bought these so bugs and other things couldn't get through and also to keep my heat an air inside. I always want to keep some of these just in case.
