Acoustic Aluminium Sliding Door



Everyone wants their home to be a peaceful space – but with bustling traffic, barking dogs, and noisy neighbours, it’s not often easy to achieve! Many aren’t aware, but the secret to blissful urban living actually lies in your choice in windows and doors. Whether you live on a busy main road, or a high-density housing estate, acoustic windows and doors are a non-negotiable addition

In fact, many new homes are required to reach a certain acoustic rating in order to receive their building certification. As such, if you’re building a new home, sound protection should be at the top of your priority list.

Luckily, at Bradnam’s, we have the technology and expertise to help you achieve the best results. Read on to learn more.


The entire structure of the home – including the walls, roofing, windows and doors – work together to keep out unwanted noise. Acoustic windows and doors, although the weakest element among these, actually play an important part in your home’s insulation – essentially determining its ability to fight noise pollution.

Said window and door performance is measured by what’s called an RW number (also known as a Weighted Sound Reduction Index). This number is used across the world as a standard by which we measure how well a window or door blocks out sound – the higher the rating, the better the performance.

However, it is important to note that glass-only RW ratings are non-compliant. Window and door RW ratings are required in order to comply with acoustic standards.

Protecting the peace in your home is not a simple task! Thinking about acoustic protection is important, and ideally, should be detailed in the design phase.

When it comes to your windows and doors, some design practises worth considering are:

Strategic Positioning: Never underestimate the power of positioning. The location of your windows and doors within the home have a significant impact on their ability to block out noise. Prepare accordingly.

Seals: Level up your home’s protection from noise pollution by selecting products with high-quality seals. Sound can easily penetrate windows and doors through gaps between the glass and frame – so seal the deal with quality acoustic windows and doors.

Product Combinations: Different types of windows and doors will perform better acoustically than others – so take this opportunity to mix and match your selections for improved acoustic performance and style! For the best acoustic results, we recommend a mix of fixed windows, awning windows, casement windows and sliding doors.

Maintenance: Give your windows and doors the TLC they deserve, and regularly check your seals. Through everyday use, they may need to be replaced over time.
