The Top 10 Best Door Sweeps for Soundproofing [2021]

Last updated on September 2, 2021

Looking to stop noise from coming into your space from another side of the door? Use one of the best door sweeps for soundproofing.

Which door sweep is the best for soundproofing anyway? It’s this soundproof door sweep.

Living with noisy roommates, I have learned that one of the best ways to soundproof a door is to roll up a large towel and stuff the gap under the door. It reduces the noise significantly (provided there are no other gaps around the door’s frame.)

But you don’t have to resort to the poor man’s solution because there are some great and inexpensive door sweeps you can get to do the job perfectly. Their purpose is more about blocking drafts and keeping the room temperature in control, but soundproofing is often their great benefit.

So what do you have to choose from? Basically, most door sweeps are similar to the good old rolled-up towel. You have two choices — a silicone strip or a foam roll (usually covered in vinyl or fabric). Both options work great, but we have our favorite.

When choosing your door sweep, most importantly, not the size of your door and the height of the gap underneath it.

Do door sweeps reduce sound?

Door sweeps reduce sound if they cover the gap between the door and the floor completely and there are no other gaps in the door frame. You can weatherstrip all gaps if needed.

How do you soundproof the bottom of a door?

Use the correct size of a door sweep to soundproof the bottom. Make sure it’s thick enough or has multiple layers for best results.

Should a door sweep touch the floor?

The door sweep doesn’t need to touch the floor if there’s a threshold bevel. Otherwise, it has to touch the floor to seal the gap fully.

Why is there a gap under my door?

There can be multiple reasons for the gap under a door. For one, a gap is necessary if the floor is not level. The door touching the floor would damage it over time. Another reason is letting the air out of the room when closing the door, thus equalizing air pressure between the rooms.
