The best windows for noise reduction
April 18, 2019 admin

Homes should be peaceful and quiet from the outside world. It’s easy to shut a door to stop wind or to close the curtains to eliminate light, but it’s not quite that simple when it comes to noise.

In general, the majority of sound enters through windows, being that a windowpane is usually 3mm thick. This does little to insulate against noise, regardless of whether a window is open or closed. So what options do you have if you’re sick of noise and it’s starting to impact your life?

Should I retrofit new windows in existing frames?

Choose uPVC and double glazing for noise reduction

You may be wondering whether retrofitting your existing frames with new windows will help reduce noise. So let’s take a look at the possibilities. To understand the noise reduction abilities of windows, it’s important to first take a look at the types of windows on the market alongside their Sound Transmission Class (STC). Keep in mind that a window can have an STC rating of anything from 18 – 38, with 38 being the highest.

Single pane: 26-28 STC
Double pane: 26-32 STC
Soundproofed single pane: 48-54 STC
Soundproofed double pane:48-54 STC

These ratings aren’t final, but they give a good indication of what is expected with each type of window installation. As you can see, replacing existing window panes with a higher quality single or double glass still won’t exceed more than a 50% reduction. Acoustic experts generally say that for there to be a noticeable difference in noise reduction, at least 75% is required, so just replacing glass alone will not suffice.

What are the best windows on the market for noise reduction?

Choose uPVC and double glazing for noise reduction

To put it plainly, double glazed windows with uPVC frames are the best option for noise reduction. uPVC frames are built with unplasticised polyvinyl chloride, and unlike traditional wooden or metal frames, they don’t require sealing (or painting). This not only aids in noise reduction, it also significantly reduces the maintenance required over the lifetime of the window. Pairing a uPVC frame with a double glazed window further enhances insulation and is the best bet for noise reduction. This combination also provides numerous other benefits over traditional windows such as self-extinguishing abilities, high wind load performance and rot-proof characteristics.
