Sound protection is becoming increasingly important when building a new home. Living on or near a main road, in medium to high density housing estates or underneath a noisy flight path are all situations where you may need to consider ways to reduce noise transmission around your home. Many new homes are required to reach certain acoustic ratings to ensure they receive building certification.
Sound and your home
The entire structure of the home – including the walls, roofing, windows and doors – all work together to keep out unwanted noise. When it comes to your windows and doors, they can really have an impact in helping insulate your home from noise pollution. Sound travels in a variety of ways, so it is important to note that window and door frame design, seal type and glass type all play a part in noise reduction.
The acoustic performance of windows and doors is measured by an RW number (also known as a Weighted Sound Reduction Index). This number is used internationally, as a standard by which to measure how well a window or door blocks out sound. The higher the rating, the better the performance of the window or door at blocking out sound.
Good Design Practice
Thinking about acoustic protection is important and ideally should be detailed in the design phase. Using good design practices can help you plan for ways to limit the amount of unwanted noise that enters your home.
When it comes to your windows and doors, some design practices worth considering are:
Positioning: The way that windows are positioned in a space can have a big impact. It is important to carefully plan the layout.
Seals: Using high quality, full perimeter seals on windows and doors in noise prone areas throughout the home will help protect from outdoor noise pollution.
Product Combinations: Different types of windows will perform better acoustically than others. For the best acoustic results, consider a mix of fixed panel windows, awning windowsand casement windows with full perimeter seals, and a high quality, double glazed laminate glass for added protection.
Maintenance: regularly check seals – through everyday use, seals may need to be adjusted over time. Dirt and grime can build up in windows and door tracks so it is best to ensure that these are wiped out on a regular basis to help them operate at their best.
