Assessing a Floor for Soundproofing
When soundproofing a floor there are various elements to look out for when you are progressing into the world of soundproofing, we will go through these step by step to give you clarity when looking to purchase soundproofing.
You are welcome to call on 01937 588 226 to go through in more detail.
Our document on ‘Science of Soundproofing’ goes into more detail about how sound works.
iKoustic provide a variety of different options depending on the results you are looking to achieve, the space you can lose and of course your budget.
Assessing the property
At this first stage you will want to investigate the current make up of your floor as well as adjacent walls for flanking as best as possible. (we will come on to Flanking on part 3)
Properties differ from each other depending on their period of construction and size -where most apartments will be constructed of concrete, early period and single dwelling properties will in most cases be a brick and timber construction.
Another part of the assessment is to indicate whether the building is listed or not, this would determine what solutions we can put in place.
- Structural Wooden Joist
With structural wooden joists, these will be of a large depth in most cases of 200mm + and depending on the properties age, a variety of joist filling materials could be present such as sawdust, sand or lime pugging. If the property has gone through a recent renovation, Mineral Wool may be present which could be as soft as loft insulation or in some cases a much denser Mineral Wool which could be an acoustic grade and beneficial to the overall performance.
- Existing Floorboards
Depending on the age of the property, flooring could range from a traditional nailed down, exposed floorboarding which would appear to be thinner slats, to more recent constructions of a chipboard or ply flooring which would appear less desirable.
- Direct Fitted
Floors can be direct fitted to the concrete, once any existing flooring is removed you will find the concrete structure underneath
- Suspended Flooring
Underneath the structural flooring, this would appear to have large timber battens across the flooring to suspend away from the concrete slab. There may be a joist filler in this cavity which would be like the Structural Wooden Joist.
What are the noise issues?
Noise can come in various forms in which you may be familiar with, this is Airborne, Impact or Structural Vibration
These can be present in all types of construction and the severity of this can be dependent on construction too. For example, due to the density of concrete – sound will tend to travel further as a basic principle which is why impact noise is more of a concern in these types of constructions.
We have listed a quick summary of common noise issues below;
- Airborne; conversation, television, music, kitchen appliances in operation
- Impact; footfall, moving furniture, doors shutting
- Vibration; similar principles as impact noise as well as mounted audio devices on walls, other external noises
Are there any flanking issues?
Flanking Transmission is a term you may have heard of, but if you haven’t – this is where sound takes an alternative path so in the case of treating a floor you will want to investigate whether sound is also transferring down adjacent walls.
What Flooring Soundproofing options are there available?
We have a range of systems available for flooring in which the 3 variables you will need to consider is budget, performance and space loss.
We can help to pick the best option for you, you can contact us via email on our Contact Page, or call us on 01937 588 226.
