Triple glazing and noise reduction

Recent years have seen window technology come on leaps and bounds and since windows are essentially the fabric of the building - their job has become increasingly important in terms of noise reduction and thermal insulation. With so many options nowadays, home owners often find themselves wondering if triple glazing is a worthwhile investment and upgrade on existing single and double pane windows. Triple pane windows provide a step up from double glazed windows for various reasons. Let's examine them:

Reduction of Noise Pollution

With the many existing ways to improve sound reduction and noise cancelling, triple glazing is a cost-effective alternative that produces long-lasting and reliable results. The three panes of glass and two spacers make them better insulated in terms of heat, noise and performance.

Triple glazing is known to reduce noise penetration more than double glazing as this feature is a factor of two things:

The thickness of glass

size of gap between panes

Window panes of equal thickness block noise of equal frequency and a triple-glazed window with 4mm panes each separated by a 14mm gap (adding to a 40mm thickness overall) will provide better noise reduction than a double-glazed window. The thickness of the glass used is one of the key elements of the sound insulation. As different glass thickness blocks a different frequency, ideally the most efficient way of keeping noise out is achieved through a combination of panes of different thickness. This is a method known as asymmetrical glazing, where even the weight of the glass plays an important part as the compact mass reduces sound.

The two compartments, resulting from the tree panes of glass add to the sound reduction of outdoor noise that is being transmitted through the windows. The specific structure of triple pane windows makes them more suitable to cover a wide array of noise frequencies - from low to high - which is a common occurrence in urban areas, providing the best sound insulation.

Heat absorption

When compared to double-glazed windows - triple-glazed can save 2 to 3% of your usual heating bill during colder months, which makes them a worthwhile investment. When comparing the SHGC, or U-values, there is an obvious improvement of about 20-30% in the energy ratings of triple pane windows. Scandinavian countries like Sweden and Norway have recently started to adopt triple glazing as the standard as it takes down the U-value of the windows to around 0.8. This is a considerable improvement as it provides consistency in the insulation of floors, walls, roof and windows and eliminates the issue of condensation. The lower U-values make triple glazing more energy efficient and in combination with a fiberglass pane - this alternative performs better than double glazing and is extremely durable.

Given the fact that modern insulation results in colder windows - triple glazing is an ideal solution to eliminating cold patches in your house. Coupled with its significant reduction in noise pollution - it becomes clear why it would be the better choice for people living in urban areas with lots of traffic and other noise pollution.
