Most of us living in South Africa are exposed to high levels of noise pollution on a daily basis. The rapid pace of urban development, traffic congestion, aeroplanes, taxis, diesel generators running during loadshedding and construction work are just a few examples of the noise sources contributing to our cities’ overall loudness.
If you live in a busy area or close to a noisy street, you might have wondered if it’s possible to soundproof your windows. We have some good news! The answer is yes. It’s not only doable to soundproof windows, but it can significantly reduce stress and health ailments associated with high noise levels.
What Does Soundproofing Mean?
Soundproofing refers to the process of reducing or eliminating unwanted noise from entering or leaving a room or building. Sound travels in waves, and soundproofing materials work by either absorbing, reflecting, or blocking the sound waves. The effectiveness of soundproofing depends on various factors, such as the noise source, the materials used, and the construction of the building.
When it comes to windows, the type of material used plays a crucial role in determining the level of sound insulation. Aluminium windows are a popular choice for both commercial and residential buildings in South Africa due to their durability, safety, energy efficiency, and aesthetic appeal.
Can aluminium windows be soundproofed?
The good news is that aluminium windows can be soundproofed, and there are various methods to achieve this. Let’s take a closer look at some of these methods.
- Double glazing
Double glazing is a method that involves adding a second layer of glass to the window frame, creating a gap between the two panes. The opening is filled with air or gas, such as argon, which provides additional insulation. This method effectively reduces noise levels, as the extra layer of glass and the air gap act as a sound barrier.
- Acoustic laminated glass
Acoustic laminated glass is another effective method for soundproofing windows. This type of glass is made by bonding two or more glass panes together with a layer of plastic in between. The plastic coating helps to absorb sound waves, making it an effective sound barrier. This method is advantageous when noise pollution is a significant problem.
- Soundproof curtains
Soundproof curtains are made from heavy materials, such as velvet or suede, and are designed to absorb sound waves. These curtains can be hung over existing windows, creating an additional layer of insulation. Soundproof curtains are a cost-effective way to reduce noise levels, but they are not as effective as double-glazing or acoustic laminated glass.
- Sealing gaps and cracks
Silicone sealant or weatherstripping can be used to seal gaps and cracks around the window frame. Cavities and cracks allow sound waves to enter or leave the room, so sealing them can create an effective sound barrier.
While these methods can significantly reduce noise levels, they won’t completely eliminate all sound. The level of noise reduction depends on various factors, such as the type of noise, the materials used, and the construction of the building.
If you’ve tried everything to soundproof your windows, but high noise levels are still perturbing, keep in mind that South Africa has laws in place to regulate noise levels. The Noise Control Regulations, which form part of the National Environmental Management Act, specify acceptable noise levels for different times of the day and different areas, such as residential or commercial areas.
