  • Saves energy and reduces heating costs

  • Quick and easy installation

This kit, together with an additional glass layer, is a superb choice to help in soundproofing a window and minimize the sound originating from outdoors.

But you can try attaching an additional laminated or acoustic grade glass, or piece of acrylic over your windows’ inner surface.

Remember that you’ll need to install a metal frame on your window to join the new layer in the right way.

This choice can offer sufficient sunshine, and you can fast take out the frame to clean up your window. Conversely, it’s a costly solution that needs the effort and time to install.

  1. Using window plug

This the easiest solution to the window noise issue. A window plug is simple to build, is created with cheap materials, and is very effective.

A window plug works by using layers of wood, soundproof matting, and acoustic foam to fill the gap in front of the window.

The wood backer board and the mat block any sound that enters the foam. Handles are added to the wood’s back surface to make installation and removing easy.

Plugs have the benefit that they are permanent. You can add them when you want and remove them when not. And this is great as they do come with some major drawbacks.

First, they are especially appealing, either from across the road or inside your home. In addition, they help in blocking all entering light.

If the sound issue is continuous, you will not have the chance of taking out the plugs. This means that you won’t enjoy natural sunshine during the daytime.

If you reside in a region that has a lot of light pollution, the light-blocking properties of these plugs can be an advantage.

To create window plugs to should first measure the depth, width, and height of the window gap. Make the plug a bit taller and wider than the window gap to guarantee a firm seal.

The measurement of the window depth is essential as it can establish the thickness of the plug.

Keep in mind that when calculating this thickness, you should leave one inch of space between the window glass and the plug’s foam.

To create the barrier, you should cut the wood board, soundproof mat, and the acoustic foam to size a bit wider and taller than the window gap. After that, glue the foam to the mat and the mat to the wood.

Once the glue dries, just press the plug tightly into the window gap, which leaves a small opening between the glass and the foam. You will see a great reduction in the intrusion of sound.

  1. Sealing all the openings around your windows

Windows may have some gaps around them, particularly space where they’re attached to your walls.

Though these openings might appear small, they permit lots of sounds to enter the room.

You’ll find ways of sealing the openings that include acoustic caulk and weather stripping. In weather stripping, you’ll require weather stripping tape.

This tape is created with materials like silicone, foam, rubber, and others. You can select your preferred material based on the windows.

The best weather stripping tape, which serves as the best opening sealer is a closed-cell foam tape. It’s waterproof, airtight and inexpensive.

It is easy to install the weather stripping tape. All you should do is clean up the area you would like to stick the tape.

After that, cut the tape based on the window’s size. Simply apply the strip on the widow’s four sides. Repeat the whole procedure for all your home’s windows.

An advantage is that this strip will help prevent water leakage through your window and provides you with protection against bugs as well. Additionally, you can seal the tiny openings on the windows with acoustic caulk.

The installation procedure is fast and simple. Ensure that you clean up the surface you’re applying first. Dust and dirt hinder acoustic caulk’s elasticity and curing time.

When you have a clean surface, the caulk can stick better when it’s unclean. The caulk is more durable compared to standard caulk and offers a 3-year guarantee. It’s made to be flexible, helping to keep it shrinking-free.
