One of the most significant noise sources you need to deal with when you have a Velux window is rain. But other noises can also get into your home through the window. For this reason, it is essential to know what factors you need to consider when installing a Velux window.

When installing a Velux window, the first thing that you need to consider is your glazing. You must make sure that your Velux window has a double or triple pane of glasses. This way, the window will have the ability to block the noise from getting into your home. 

However, it is worth noting that not all double or triple-paned windows are the same. So, you should consider the size and the gap of each pane. The more significant the gap, the more protection you will get against annoying sounds. 

Additionally, proper installation is also essential as it plays a significant role in blocking the noises and preventing them from disturbing you.

That said, you should hire a professional roof window installation service. It will help you make sure that your window is fitted securely without any gaps. A professional doing the work is also an assurance that there will be no errors in the Velux window installation. 

After installing your Velux window, you can use accessories to further soundproof it. For instance, you can use soundproofing blinds that can also block the sunlight when it becomes too hot. In addition, there are many Velux window accessories that you can purchase. That includes shutters and roof window blinds. 

Furthermore, combining these three considerations when having your Velux window installed will allow you to get satisfying results. Doing this will also ensure that you are blocking the noises made by the rain and other kinds of noises from bothering you.  

Steps To Soundproof Velux Windows

The noisiest types of Velux windows are the ones that are single-paned as they do not provide enough insulation from external noises. If you know that your Velux window is single-paned, consider replacing it with a double or even triple-paned Velux window. 

Such will allow you to dampen the noise coming from the outside effectively. However, if your window is already triple-paned but the noise persists, then another option is fiberglass insulation. 

Here are the steps that you can take to soundproof your Velux window:

1. Determine your window’s pane number

You can do this step visually. Each pane is parallel to one another. For this reason, looking at the window from an oblique angle will allow you to see the edges of the glass. 

Once you found out that your Velux window is single-paned, that means it cannot block outside noises from passing through it. It can even amplify any noise, including raindrops. 

2. Pane replacement

Now that you have examined your window, it is time to replace it with a double or triple-paned one. This step will allow you to reduce the ambient noise from outside and the amount of heat that can get into your room through the window. 

You can get a double or triple-paned Velux window from a local hardware store. Most of the time, they also offer installation for additional installation service that comes with an extra charge. 

3. Get fiberglass installation

Alternatively, you can opt for fiberglass installation to soundproof your Velux window. The person who will install it will layer the fiberglass around your Velux window’s shaft. As a result, the noise that passes through your Velux window will be significantly reduced. 

People with double or triple-paned windows can also install fiberglass. Doing such will further reduce the noise coming in from the window. 

How to Take care of Your Velux Window

Your Velux window may be sturdy and durable. However, without proper care and maintenance, it will have to be replaced in the long run. That said, you need to ensure that you are taking care of your window to remain an excellent design for your home. 

The first step to maintaining your Velux window is to keep the panes clean all the time. You can rotate the sash 180 degrees for you to reach the outer pane for cleaning. But it is important to note that you must keep the sash secured in its position. 

To do this, slide the barrel bolt into the blushing that you can find right at the bottom of the side frame. It is a safety feature that prevents the window from sliding. 

Now, clean the pane using a clean, soft, and lint-free cloth. You can also use a non-metal window squeegee. 

When cleaning your window panes, it is worth noting that:

  • You should never use any cleaning products with abrasive chemicals
  • Do not use any sharp or abrasive objects cleaning your Velux window panes
  • Never try to take off the dirt from your pane without applying water first
  • If you need to do any work, such as wall repainting near your Velux window, make sure to cover it with clean plastic so you can prevent staining it

Moreover, it is also vital for you to clean your Velux window’s air filter. You can remove the air filter to clean and wash it. To do this, rotate and secure your window in a cleaning position. This way, you will be able to remove the air filter from the filter rail safely. If you can no longer clean the air filter, you can also buy a new one for replacement.

In addition, you should remove leaves and debris from the window’s flashing from time to time. This way, you will be able to allow rainwater to flow freely. 

Soundproof Velux Windows: Is it Important?

Noise pollution can be one of the most annoying things we deal with, and no one would ever want to deal with it if they don’t have to.

When noises get into your room through your Velux window, it can disturb your rest time or sleep. Fortunately, there are several actions we can take to reduce the amount of noise that is passing through. 

It is safe to conclude that soundproofing your Velux window is an important thing to do. Such will allow you to rest and sleep time undisturbed by the annoying noises coming from outside. You would not want any noise to wake you up during a good sleep, right?
