Window Noise Reduction / Sound Proofing
Today’s world is one of noise. Traffic, trains, aircraft, machinery, appliances, television and music systems – sound comes at us from everywhere, much of it unwanted.
Whatever the noise source, the correct selection of glass for the window systems and construction method are crucial for a peaceful environment. Once the required sound reduction is established for the application, a glass type and thickness can be selected.
For example, street noise is 70 dB while a bedroom requires 35dB: therefore 70 – 35 = 35dB of sound reduction required in the windows (and walls).
Thermawood Double Glazing can be used to reduce noise combining laminated glass or soundstop laminated glass in the double glazed unit to help reduce and in some cases all but eliminate the noise. It is important that the rest of the building envelope is also designed to reduce the noise, to ensure a complete barrier to the noise.
While toughened or patterned glass behaves acoustically the same as standard float glass, laminated glass reduces sound due to the vibration-dampening effect of the interlayer in-between. Special acoustic grades of laminated glass are available such as SoundStop, which comprises two glass sheets with a layer of acoustic resin.
Draft / Acoustic seals
Reducing the gaps and drafts around your opening windows is another way of reducing the unwanted noise from outside. Thermawood have a range of draft / Acoustic seals available for all opening windows from Casement, awning and double hung windows that are all machined into your windows as a permanent fitting as opposed to a stick on solution that wont last.
