How Do Roller Shutters Block Out Noise?

May 15, 2024

Roller shutters are effective at reducing noise, thanks to their design and materials. Whether you’re wondering how to block out traffic noise in the bedroom for a peaceful night’s sleep or simply wish to generally reduce noise from outside, roller shutters are a practical choice. 

Contributing Factors

Materials and Construction

Roller shutters are made from denser materials like aluminium or steel, which help block noise. Their thickness makes them even better at keeping out unwanted sounds, acting as a solid barrier against outside noise.


Built-in insulation within the shutters adds another layer of noise protection. This usually involves foam-filled slats that keep heat in or out and absorb sound, with denser foam being more effective at noise reduction.

Design Features

The design of roller shutters includes features specifically aimed at minimising noise. For example, precision-engineered guides and tight-fitting profiles ensure there are minimal gaps around the shutters when they’re closed. This tight seal prevents sound waves from leaking through cracks and crevices, further reducing the amount of noise that can enter your home.

Installation Techniques

Proper installation is vital to maximising roller shutters’ noise-reducing benefits. Professional installers ensure that shutters fit snugly against window frames, eliminating gaps and creating an acoustic seal around windows.

Secondary Glazing Effect

When installed outside the window, roller shutters can create a secondary glazing effect. This additional layer creates an air gap between the shutter and the window, providing further sound insulation. This effect is similar to that of double glazing, trapping sound waves in the air gap and reducing the transmission of noise into the interior space.

Benefits of Installing Roller Shutters

Roller shutters are a versatile addition to any home, offering several key benefits that go beyond basic security. Here’s how roller shutters can make a difference in your home:

Reduced Noise

One of the key benefits of roller shutters is their ability to significantly reduce noise from outside. Whether it’s the constant hum of traffic, noisy neighbours or the bustling sounds of the city, installing roller shutters can help create a more peaceful and quiet indoor environment. This is particularly beneficial for bedrooms or living spaces facing busy streets, helping to block out traffic or neighbourhood noise and for the improvement of  overall comfort in your home.

Increased Privacy

Privacy is a precious commodity in today’s world and roller shutters offer an effective way to enhance it. With the shutters down, you can completely shield your interior from the outside world, keeping your private life away from prying eyes. This feature is especially valuable in densely populated areas or for rooms that require additional privacy, such as bathrooms and bedrooms.

Weather Protection

The solid build of roller shutters provides a triple-layered shield for your home. They’re not just a barrier against outside noise and potential break-ins – they also stand as a formidable defence against the weather. Be it the scorching summer heat, chilly winter drafts, heavy rain or even hail, roller shutters are designed to offer protection.

Double Glazing vs Roller Shutters: Which is Better for Noise Reduction?

When looking for ways to minimise external noise in your home, two options frequently come up – double glazing and roller shutters. Each option has advantages, but just how do they stack up against each other, especially concerning the question: do roller shutters block out noise? Let’s take a look:

Double Glazing: Known for its noise-reducing efficiency, double glazing incorporates two glass panes with an air gap in between. This effectively dampens sound waves. This setup not only cuts down on noise but also enhances the home’s thermal insulation, leading to potentially lower energy bills. However, the installation of double glazing represents a significant investment and may not be compatible with every window type or architectural style.

Roller Shutters: Providing a versatile approach to reducing noise, roller shutters are constructed from high-density materials that closely abut windows, greatly diminishing noise entry. Beyond their core function of blocking out noise, roller shutters bring added value in terms of increased privacy, heightened security and improved energy efficiency. Their adaptability means they can complement existing window setups, offering a practical noise-reduction solution for any home.

The Verdict: While both options effectively mitigate noise, roller shutters shine in their multifunctional advantages. They not only tackle the challenge of “Do roller shutters reduce noise?” but also outperform double glazing because of the enhanced security features, energy savings and privacy control. This makes roller shutters an outstanding choice for homeowners seeking a comprehensive solution to noise and beyond.

Conclusion: The Clear Choice for Your Home

In the debate of double glazing vs roller shutters for noise reduction, roller shutters emerge as the clear winner for homeowners looking for a versatile, cost-effective solution. They not only effectively block out unwanted noise but also provide added advantages like increased privacy, enhanced security and superior weather protection.
