In this blog, I’ll discuss some effective methods for soundproofing skylights, as well as answer some common questions concerning skylights and how to reduce outside noise through them.
Skylights are useful home ideas that allow light to enter a space and enlighten it. These rectangular skylights are popular among homeowners who want to create a more appealing interior. Even a brand-new skylight window, on the other hand, can let in annoying noises like passing traffic or aeroplanes.
Single-paned skylights are the noisiest and give the least amount of noise isolation. If you have a single-paned skylight, substituting it with a double- or triple-paned skylight will significantly reduce noise.
If your skylight is already double- or triple-paned, fibreglass insulation will help to minimize noise even more.
Granted, some individuals appreciate the sound of rain splattering over glass windows, but for others, it is a source of sleep disruption, thus knowing how to soundproof a skylight is essential. Soundproofing a skylight used to entail entirely covering the window with some sort of barrier; this installation essentially prevents any light from entering the window. Currently, certain solutions can be used to permit light in while blocking most noises around the skylight’s surrounding curb.
How to Soundproof a skylight?
Here are some suggestions for reducing unwanted noise without sacrificing the benefits of having a skylight.
- Replace single-paned skylights with double-paned or triple-paned skylights
- Install fibreglass insulation
- Fill up any cracks or gaps around the frame
- Sound sealing for an air-tight seal
- Install soundproof curtains
- Utilise window frames or inserts
Advantages of Skylights
- Skylights provide natural light, which will save you money on your electricity costs and give your eyes a break from artificial light.
- If you reside in a cold climate, a skylight with a greater SHGC will provide you with a warmer environment.
- They’ll let in natural air and make your room more ventilated.
- You can seek professional assistance to have a skylight that is custom-made for your environment and requirements.
- During the day, you can get lost in the clouds, while at night, you can gaze at the moon and stars. This aesthetic delight is enough to entice some individuals to purchase it.
Disadvantages of Skylights
- Skylights can create a space too bright if they are not installed at a specific angle range.
- It can also make your home overly hot if you choose it without considering SHGC.
- In the winter, if your skylight doesn’t have excellent specs, you may experience heat loss.
- Skylights that are installed incorrectly might cause leaks and moisture concerns.
- You may be accustomed to opening and closing your windows when you want, but skylights are not the same.
- Sound can easily enter the space, causing disruption for some.
- For some people, cleaning a skylight might be a stressful undertaking.
Why does skylight make noise?
Skylights, as you may know, are primarily comprised of glass and acrylic.
As the temperature outdoors fluctuates during the day, the acrylic material will expand and contract gently and constantly.
A crackling sound is produced by this expansion and contraction. The skylight well in the ceiling might sometimes even accentuate this minor noise.
Replace single-paned skylights with double-paned or triple-paned skylights
Another material utilised in the construction of skylights is glass. Knowing how to soundproof it, on the other hand, can make a major difference in your ability to live a quieter life.
If your skylight is single-paned, it will let a lot of outside noise in, amplifying the sound of any noisy events like rain droplets, birds, and debris that may fall on the window. Plastic bubble skylights are the thinnest and noisiest of the skylight types, as compared to flat pane skylights.
Determine how many panes your skylight has. This can be done visually. The panes are parallel to each other, so if you look at them from an oblique angle, you can see the margins of the glass.
If possible, replace single-paned skylights with double-paned or triple-paned skylights. Both your noise problems and your air – conditioning expenditures will be greatly reduced as a result of this.
Choose a double- or triple-paned skylight from your local hardware store, which will almost certainly include installation.
Install fibreglass insulation
Fibreglass insulation can be found at your local hardware shop. It should be layered around the skylight shaft. The noise will be reduced as a result of this. This is the ideal option for further lowering noise if your skylight is already double- or triple-paned.
Fill up any cracks or gaps around the frame
First and foremost, check for any cracks in your windows. They have the potential to be a source of sound leakage.
Sealing off this section is another “Must do” phase in the noise management procedure since air and sound can seep through holes surrounding the frame.
This problem can be solved by sealing in a layer of Green-glue around the frame. A big caulking gun is required, and it is advised that the caulk be applied in a bead all around the entire frame.
You can look at other places to improve once you’ve achieved an airtight seal around the frame and there are no holes around the frame itself.
Sound sealing for an air-tight seal
To provide complete coverage and regulate sound seeping in through the frame, airgaps must be corrected. It’s great if you performed this on all sides of the frame and at the top. Weatherstripping takes little time and effort, but when done correctly, it is an excellent sound management technique.
The majority of items have a peel-and-stick feature. Surface preparation is essential since the adhesive requires a clean surface to adhere to. Although an alcohol rinse is not always necessary, it is highly suggested. The placement should be done on the frame’s inner side.
You can do this in one of two ways:
This is a hollow “D”-shaped foam rubber composite material. The Acoustic gasket seals off and stops airflow when compressed. If the gap is large enough, you may create an air pocket that works just as well as soundproofing.
Remove the protective strip from the tape to reveal the sticky side, then adhere the gasket to the framework on all sides as needed.
The most typical material for this is acoustic treated foam. It’s crushed between the inside door frame and the door itself, so sound can’t get through.
Peel-and-stick techniques are typically used for the application, making it simple to install.

Install soundproof curtains
These curtains have up to 20 STC ratings, which is about the same as a hollow-core door on its own. Nevertheless, this is only true if an MLV or comparable lining is present. The majority of “soundproof” curtains are essentially light-blocking, with minimal sound-blocking ability. When done correctly with the appropriate soundproof curtains, there will be a perceptible difference between the amount of sound that enters a room. Even at an STC rating of 10, it will sound half as loud as previously.
When you have mild sound concerns, soundproof drapes made to filter out sound waves can be a handy solution. They can also utilise it in conjunction with your other attempt to enhance efficiency.
Install a curtain rail with a width and height overlap of 4 inches. The curtain should also be hung as close to the wall as feasible. Sound will not leak out from behind the curtain as a result of this.
Utilise window frames or inserts
On an existing skylight, window inserts or frames can be used. These frames can be made to order. As frames or inserts, they cover the full window. This leaves a space between your current and new windows. The amount of sound that is blocked as a result is significant. They are difficult to install and do not allow for ventilation, depending on where your skylight is located.
A skylight can bring the beauty of natural outdoor light into your home, but it can also bring the unwanted sounds of jackhammers, highway traffic, and leaf blowers. Skylights have many uses, but they’ll require some work and make them perfect.
In this article, I’ve discussed some solutions for blocking outside noise that you can try. They can save you money, but you’ll need to inspect for any leakage. Adding a window insert or buying double-glazed windows to soundproof your skylight will make it perfect.
Frequently Asked Questions (FAQs): Skylight soundproofing
Is it possible to soundproof a Velux window?
To make your Velux window soundproof and keep any noise from going in, you simply need to install specialised, translucent panes. You can either wrap them around the curvature of your Velux window or triple-glazed them for noise reduction.
Is there any noise from the skylight?
Is it possible for an acrylic skylight to produce noise? As the temperature outdoors varies during the day, acrylic will stretch and shrink somewhat. There may be a minor cracking sound as a result of this. Because of the skylight well in the ceiling, this minor noise may be magnified substantially in some applications.
How do I silence the rain on my roof windows?
Heavy rain will be muffled by blinds that are fitted on the exterior of the window. They are designed to block the sun’s rays before they contact the glass, preventing the room from becoming too hot. Install a few shutters. Although shutters are a costly alternative, they can help reduce rain noise.
Why are my skylights so bright?
Expansion-contraction noises from the skylights were audible. This is most evident when the sun is shining and clouds are passing over it. As a result, the aluminium was allowed to expand and contract at a different rate than the steel, resulting in the popping noises.
Is it true that roller shutters filter out the noise?
Yes, roller shutters can block off undesirable sounds, but sound can still come into your home through other channels. Soundproof shutters can be purchased, which will greatly lower noise levels. However, for roller shutters to be more effective, you’ll need to combine them with something else.
Is it necessary to insulate skylights?
If the attic they travel through is not insulated, the skylight shaft walls must be insulated to the same R-value as other outside walls. Spray foam or stiff foam can be used, or SIPs can be used to form the shaft walls.
Is it necessary to insulate skylights?
While skylights can be a wonderful addition to any home, they can be difficult to insulate. If not properly insulated, skylights are susceptible to air and moisture leaks. To guarantee that the job is done correctly, it is critical to engage with a certified contractor.
Is Velux triple glazing a good investment?
Triple glazing reduces noise pollution significantly, making it excellent for those who live in busy environments. Triple glazing is a great solution to this problem since it minimises the U-value differential between the windows and the rest of the structure.
