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:

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.

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.

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).

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.
