What can I do to stop the noise coming into my home?
Everyone likes to have the convenience of living near services that they need every day like Trains, Buses, Highways and Schools but not to many people like the noise from these services invading their home at all hours of the day and night. That is where a quality home insulation specifically designed for sound Attenuation in your external walls and ceiling might help stop these unwanted noises.
Insulation is a very effective solution for stopping sound and while Thermal insulation is measured in R-Value, Acoustic insulation is rated in terms of a Sound Transference Coefficient or STC Rating. Although, these ratings do have some approximate correlation, so it is important to understand that there is a different rating system for sound insulation.
How do I stop plane noise from coming into my home ?
Cellulose fibre pumped in insulation is much more effective at stopping overhead Air traffic or plane noise. One of the main reasons is that it is pumped in and so there are no gaps but the other major benefit is that it can cover the joist timber as well. Batt insulation just lays in the bays and it does not cover the joist, so the joists become the weak spot in transferring that plane noise into your home.
Have a look at the video below and you will see the difference it makes to be able to pump the insulation in and have such a complete coverage that the maximum sound that can be stopped is stopped.
Existing floor with kids upstairs & tenants downstairs. What do I do about the Noise ?
This is the type Question I get a lot for sound insulation between floors and this is my typical advice.
Just 1% Gaps in batt insulation Reduces the sound benefit by as much as 50 -70 %
This is where batts belong and it is where most end up, in the rubbish...
