How to Make a Window More Soundproof

Soundproof windows are always a viable purchase. They not only prevent unwanted sounds from entering your home; many of them can also perform the functions of security windows. Therefore, any homeowner who purchases a soundproof safety or security window in Malaysia or elsewhere can expect to reap various benefits. Although soundproof windows do serve important functions, there are always additional steps that can be taken to make a soundproof window even more effective than it already is. Thus, once you already own a soundproof safety or security window in Malaysia, you might consider one of the suggestions listed in the following paragraphs to make it even more useful for the prevention of sound transmission.


The use of fabric can increase any soundproof window’s resistance to sound. No matter the type of fabric used, most are able to absorb noise that enters a room or home. The most effective fabrics for making a security window or any other window more soundproof are polyester, velvet, and burlap. On the other hand, it is not advisable to use vinyl, acrylic, or leather for this purpose. These fabrics reflect much of the sound energy and therefore cause your security window to become less soundproof, not more. You might consider placing rugs made of suitable fabric near your soundproof window. Another suggestion is to hang curtains over such a window. Some might even choose to place furniture covered in a sound-absorbing fabric near the soundproof window. No matter the exact manner of application, all use fabric to make a window more soundproof.

Secondary Glazing

If your noise-related issues are not too severe, secondary glazing is a viable and affordable option for increasing the effectiveness of your soundproof window. Secondary glazing, as is implied by its name, adds a second sheet of glass to any soundproof window. The thicker this sheet of glass, the more the window will be able to shield you from sound. It may also be helpful to place a layer of polyvinyl butyral between both sheets. Doing so will reduce the amount of noise you’ll hear without reducing the clarity of the glass. If there is a large gap between your soundproof window’s glass panes, it will be better at protecting you from undesired sound. To make your soundproof security window even more effective, you could also choose to have a heavy gas such as argon added between the panes. Heavy gases muffle noises that enter a room; they can do so when used with any type of window including security windows.

Acoustic Sealants

Also known as acoustic caulk, acoustic sealants are fluids formulated to make a non-soundproof window soundproof or to increase the effectiveness of a soundproof window by absorbing sound. They can be used on any window, whether a conventional or a security window. Acoustic sealants do not harden and will remain flexible. They are also a permanent noise-reducing solution because of their high degree of durability. Acoustic sealants will neither crack nor shrink. Non-flammable and non-toxic, most acoustic sealants work well with windows made of any material; wood, concrete, and metal windows, whether conventional or security windows, can all benefit from these sealants.

Soundproofing Tape

Soundproofing tape can be used to enhance the efficacy of any soundproof window. This tape is used to fill any tiny gaps in a security window or any other window. Its texture makes it customizable and suitable for use by most people. Soundproofing tape is easy to install; it will cover the gaps of any soundproof window including a soundproof security window. To install soundproofing tape on your soundproof window, you may either use glue or double-sided tape. Cut the soundproof tape according to the size of your window’s gaps. Once installed, the tape will absorb and reflect any sound waves which might make their way into your room.

Interior Acrylic Sheet

Similar to secondary glazing, an interior acrylic sheet is only suitable for conventional or security windows which only need minor soundproofing. Before this sheet can be installed, a metal frame must first be installed over the existing soundproof window. After this installation, magnets will be used to attach the acrylic sheet. However, not all generic or security windows lend themselves well to the installation of an interior acrylic sheet. For example, it is very difficult (and in some cases, impossible) to install this sheet over double hung windows. Therefore, ensure that your soundproof windows will be able to work well with an interior acrylic sheet prior to installation.

Even if your security window is already soundproof, you can never go wrong by choosing to reinforce it. After all, noise pollution is a serious problem. It isn’t just irritating - it can be a cause of serious health problems including tinnitus, hearing loss, fatigue, and even cardiovascular disease and cognitive impairment. As long as you make use of the proper steps to make your window, whether it be a generic or a security window, soundproof, you can expect to enjoy a more peaceful and stress-free life in your home.
