However, there are various effective methods with the help of which we can soundproof these windows and let less sound filter into our spaces, giving us a peaceful and calmer environment.
We will guide you through the various ways by which we can soundproof our windows and also discuss their advantages and disadvantages. In addition, we have also listed out tips and tricks that will help you in achieving the maximum and best results and also details on materials and products available in the market.
Why Soundproofing for Windows is so Important

Firstly, Sound is an energy form that travels through vibrations that create sound waves. These waves can be transported through mediums such as air, water, etc. Moreover, Noise pollution through air is the most common and can give us a lot of unwanted stress, disturbances and also hurt us physically and psychologically.
The easiest way for sounds to travel into our homes and offices (through air) is through doors, windows, etc. Windows make for the weakest points in buildings for the purpose of sound insulations and even the smallest of gaps or cracks can allow the noise to flow in easily.
Therefore, it is extremely crucial to soundproof our windows so as to reduce the filtration of noise pollution into our spaces.
How does Soundproofing for Windows Work

Sound waves are created by vibrations; vibrations that can be caused by anything such as human voice, the strum of a guitar or the keys of a piano. These waves travel by means of air, water, etc., and when they reach our ears, they transverse into sounds.
Basically, Sound is measured through decibels (dB) and the range a human ear can bear is from 0dB (silence) to 120dB (painful). Soundproofing can be obtained by ways of either blocking sounds or sound absorption. Thus, to block these waves, we need to create a physical barrier to stop them from passing through.
These barriers need to be airtight for us to be able to achieve the optimal level of soundproofing. The effectiveness or levels of sound absorption are measured through NRC (Noise Reduction Coefficient), that ranges between 0 to 1 (no absorption to complete absorption).
Blocking or absorption, both techniques can be used when you are looking at “Soundproofing for windows”. If you want to block out the sounds, you can use products like double pane windows that act as a physical barrier and block out all sounds.
While for absorption, you can use acoustic blinds or curtains that absorb the sound waves and help reducing the transmission of noise and sound.
Factors one must Consider - Soundproofing for Windows

There are several factors one must consider before finalizing on the kind of soundproofing for windows. For you to achieve the best possible results, we have listed some of the factors that needs to be considered:
1. Noise Type: The first and most important factor to consider while deciding on soundproofing is the type of noise. Different noises require different kinds of treatments – living near a busy street and do not want the noise to disturb you? Or a conference room or a wedding venue where you do not want the sound to travel out? Both require different materials and treatments.
2. STC or Sound Transmission Class Rating: This is a rating term used to measure the ability of a material to block sounds. The effectiveness of the materials ability to block sound waves depends on the higher the STC rating is. Depending on the sounds you need to block out, check the STC rating of materials to be installed and if they are compatible with your requirements.
3. Budget: Soundproofing for windows is expensive, be it a window, a door or even your full room or house. It is extremely important to determine the budget for the kind of soundproofing you require before falling into action. There are also several DIY projects and options available in the market that are much more cost effective. Or there are also materials such as soundproof curtains or even sealing any cracks or gaps to make the space airtight and hence soundproof. All these factors can be determined on the level of soundproofing you require.
4. Aesthetics of your space: Soundproofing materials are generally bulky and eat up a lot of space in your room; and can sometimes even look unsightly. It is essential to consider the impact it will have on the aesthetics of your room before finalizing on the materials.
In recent times, there are also several panels and panes designed to match the décor of your room or which can be painted or covered in fabric, but they generally tend to be slightly more expensive.
5. Society or Builder rules and regulations: There are several builders or societies that do not allow alterations to the structure or even disturbances to the outer elevation of the building. Some materials may cause a hinderance and hence it is important to cross check with the builder or society before starting on any projects.
All these factors can help you determine the level of soundproofing that is required and also the perfect materials to solve the crisis you have been facing. Whether you are aiming to block external sounds from filtering in or sounds from inside flowing out, soundproofing windows can give you the calm and peaceful atmosphere you require for a healthy living.
Options Available - Soundproofing for Windows

The layering is done as per the level of sound absorption required. These are the perfect tools for blocking out mid-frequency sounds but are incapable of blocking out high frequency noises. Maintenance is another aspect to consider as these acquire dirt easily and need a regular does of cleaning.
2. Window Inserts: These are also known as secondary glazing and are typically an additional layer of acrylic or glass installed over your existing window frame (typically on the inside of the frame). They are installed in a way to create an air gap between both the layers and that helps in blocking out or absorbing the sound waves.
These window inserts are highly effective and work well with both low and high frequencies. Also, they are energy efficient and do not hinder the décor of your room. However, these window inserts are slightly more expensive and definitely need experts to install them.
3. Weatherstripping: Silicone, adhesive tape, foam, etc., are used to seal and fill all the cracks and gaps around the frame of the window. These are cost effective methods for not only reducing the noise but also provide energy efficiency and prevents drafts.
The drawback here is that they require regular maintenance and may need to be replaced frequently and are also not effective with high frequency sounds.
4. Double Pane Windows: Insulated Glass Units (IGU) or Double Paned Windows are typically two glass panes that have an air gap in between or can also be insulated glass. These windows are energy efficient and effective in noise reduction.
They also add an addition safety barrier for your home or office as these windows are extremely strong. These windows are customizable and are available in several materials to match your requirements – such as wood, vinyl or even aluminum.
The drawback to these windows is that they tend to be on the slightly expensive side and also require you to hire a professional to install.
