Soundproof windows can help out if you have trouble sleeping. Especially if the reason you can’t sleep is that the noises of the outdoors are too much for you, namely those street noises.

One of the easiest ways, yet often forgotten, to soundproof your house is to soundproof your windows. Soundproofing your windows is an important step so make sure you don’t forget them when soundproofing your home. 

What Are Soundproof Windows? 

Soundproof windows can refer to either a window that is soundproof naturally or windows that have been layered and sealed to cancel out sound. The methods are similar to the way one would soundproof a room

You can seal it, put up barriers, and even use temporary means to get some relief from the sound. Some people simply move furniture in front of their windows as quiet is more important than a good view in their eyes. 

But most of the time, something more than a dresser in front of the window is needed. We will go over both permanent and temporary solutions that can help you block out those street noises and get some sleep.

Installing Noise-Canceling Windows

One easy way to soundproof windows is to get laminated glass windows that are made to be soundproof. These windows can cancel nearly 100% of outside noises and block them from getting into your house.

This works because laminated glass has an extra protective layer of plastic that provides a sound barrier. Whereas other glass does not offer this soundproofing quality and sound can get through fairly easily.

So if you want a permanent solution that should be paired with sealing your windows, then get some good noise-canceling windows. You will probably need to hire a contractor for this job for practical reasons.

How To Soundproof Windows With Sealant 

Soundproofing windows can mean a variety of things. But we are going to go over the surest way to soundproof windows in your home after you install new soundproof windows using caulk to seal the edges. 

Here we have a short guide that will help you caulk your windows by first removing the old caulk and applying the new caulk the proper way. Don’t forget that this is just one step you can take, but it is the most important one.

Step 1: Ensure It Needs Re-Caulked

Unless there is no wind at all outside, you can hold a small flame up to the edges to find out if the air is passing through. If the flame moves, then air is passing through and the windows need to be caulked. 

Another way to tell is if the windows ever rattle. Say, whenever the front door is shut or whenever it’s windy outside. While these are weatherproofing tips, they work for soundproofing as well because gaps let more sound in.

Step 2: Remove Old Caulk

There are a few ways to do this. You can either try scraping away any old caulk with a putty knife dry or you can use a softener to ensure it soaks for a few hours. Then, try to scrape it off and it should peel right up. 

You can do the same thing for window glazing if your windows have been glazed before. Make sure you apply a softener that works for glazes to let it soften and it will peel up like glue, flaking as it does. 

Step 3: Applying New Glaze 

After you clean the window and the window seal, you can apply a new glaze and caulk. You can re-glaze the entire window if you like but make sure you buy the correct type of glaze for your window. 

Then, apply the caulk by using a caulking gun and following the instructions on the bottle. The caulk will dry out after it is opened so don’t open it until you are ready to use it. It should take a day or so to dry completely after applying it.

  • Can Be Hard To Install

    While it can be easy to install window insulation kits in perfect conditions, if you have anything holding you back, things change. AC units, strange window sills, non-symmetrical windows, and other things can make things difficult. 

  • Voiding Your Warranty

    If you apply a window insulation kit to your window there’s a good chance it will void the warranty in place on your window. So check the warranty conditions of your window manufacturer before getting started. 

  • Not Permanent 

    Window insulation kits are great for the winter months, but they won’t offer long-term relief from the outside elements. Especially not for soundproofing. But it can offer relief while you are preparing for something more secure. 

  • Hard To Uninstall 

    This depends on the type of insulation kits that you use, but in general, it can be tricky to remove them. Most of the time, the tape can leave marks on your paint or be difficult to peel off in the first place.
