However, soundproofing sweeps will give better results than household items.

Most of the soundproofing door sweeps come with soft rubber gasket. Others come with dense brushes. This makes most of the door sweeps effective.

Let’s discuss how each type of door sweep functions.

1. Draft Stoppers

Draft stoppers function just like its name suggest. They are long pillows. They have a heavy filling in them. They prevent drafts from entering your room. At the bottom, they have a large flat surface the size of the stopper. This helps it to slide easily under the door.

The draft stopper soundproofs a door easily.

Soundproofing requires density, mass, or both. Draft stopper comes with both properties when installed under the door. Even better, they have added weight on every side. This eliminates the slamming noise when shutting or opening the door.

Draft Stopper

If you are thinking of using household items to act as a draft stopper, don’t worry. It’s easy to make draft stoppers on your own. Staffing a towel under the door acts as a draft stopper. Other options would include using a long stretch of fabrics, foam products, or even pant legs. Basically, using any material that can be stuffed below the door and cover the air gap between the door and floor.

Making your own draft stopper at home could be a perfect idea if you are under budget. Use a hot glue gun to create the shape of your draft stopper. To gain the right density, stuff it with bagged or loose beans, rice, or sand. The final step would be to install it under the door.

However, if you are looking for a more professional draft stopper, buy them on Amazon. You will get a draft stopper of your choice. You will be able to get materials that are ready to install. With ease, all your noises will be blocked from entering your own house.

Installation of Draft Stoppers

Draft stoppers are the easiest to install. You just slip them under your door. Most of the draft stoppers have padding over them on both sides. They are also made of fabric.

Therefore, when slipped over the door, draft stoppers pad on both sides of the door. As a result, the door holds the draft stopper tightly against the floor. When the door slides over the floor, the draft still remains intact.

Draft stoppers have a fabric cover. This is what makes them easy to slide over the floor. The padded sides make the stopper hold firmly over the door when it’s moving over the floor.

Other stoppers have wrap-around clips. The clips are installed over the door. The stopper is, therefore, installed over them. Alternatively, you can get the draft stoppers with a magnetic strip over them. The magnetic strip is installed under the door. The draft also has magnetic beads that get attached to the door.

2. Rubber Door Seals

Rubber door seal primary purpose is to soundproof. Unlike, the draft stopper they don’t prevent dirt from entering the house. Their design is to ensure that sounds don’t go out. It also prevents noises from outside from entering the house.

Rubber door seals have two parts; plastic or metal bit and a rubber strip. The metallic or plastic part hung over the door. The rubber part touches the floor. The rubber part is what blocks the air gap. It dampens any sound coming or leaving a room through the door gap.

Rubber Door Seals

The metallic/plastic part has embedment for fixing them over the door.

In the market, there are various brands and types of soundproof rubber door seals. Other rubber seals come with dense brushes or gasket.

Rubber seals with gaskets make the doors airtight. Gaskets are materials fixed over the doors of cooling units or refrigerators. Their role is to make the doors airtight. As a result, they dampen all noises leaving or entering into a house.

When choosing a rubber door seal, buy solid rubber seals. They are effective. Compared to nylon brush sweeps, they give better results in soundproofing a noisy area. The nylon sweeps also drag on the floor when it’s opening or closing.

However, as compared to draft stoppers, rubber seals are difficult to install.

Installation

We have already seen that rubber seals have two parts. The rubber and metallic or plastic part. The plastic or metallic element of the door seals have holes drilled over them. These holes are for screwing the seal over the door.

Most of the rubber door seals come with screws. These are screws needed for attaching them over the door.

Therefore, to install, check the number of screws that comes with your rubber door seal. Screw them over the holes on the rubber or metallic part.

Installation Rubber Door Seals

But first, start by measuring the seals over your door. Check whether they can fit well. If the seals are too long, cut them to the desired size. Remove the extra parts before you attach them on the bottom of the door.

This is the only procedure you need to apply when installing the door sweeps over your door. Installing the rubber seals are more complicated than draft stoppers. As we discussed, draft stoppers you only squeeze them below the door.

In this case, use the door sweeps.
