Sound Proofing Wooden Floors

We must get at least 200 requests a month on Sound Proofing Wooden Floors. This is a simple operation however the process must start at the building stage of the home. Having said that there are a few ways to cover the existing floor. In this post, we will try and touch on both aspects of Sound Proofing Wooden Floors. In fact, Noise Pollution is very unpleasant when the problem can’t be solved.

Sound Proofing Wooden Floors in Existing Homes

This application is a little more complicated than doing the installation at building stage. The biggest problem with floors that are already in place with a ceiling below is sound transference. Sound transference is carried from through all components.

 Floor to the Wooden Beams to the Ceiling. As all components are attached the sound travels through all three. Fitting insulation between the floors and the ceiling will result in a reduction of speech noise. However, the walking noise will still be the same. The benefit is that you will reduce talking and TV noise.

However, to do this either the floor must be lifted or the ceiling removed. This will add cost to the application. Ideally, two layers of 135mm Aerolite Insulation must be fitted tightly between the beams. There must be no airspace gaps between top and bottom.

The 135mm Aerolite Insulation has an NRC 1.1 so installing two layers is great your NRC will be in excess 2.2. The wonderful thing about the Aerolite is that the fire rating is also Class A/1 this means Aerolite will not burn. In fact, this insulation has the best fire rating in South Africa. This is essential between floor and ceiling space.

Application Were Floor Boards Have Been Removed

This is the ideal scenario rather than removing the ceiling. As this application allows for the reduction of walking noise. In this application, all the Floor beams will need to have a 10 to 15mm Sondor rubber fitted all along the length of all beams.

The advantage of fitting the Sondor rubber is to reduce the impact noise of walking. This will however not remove this type of noise totally but it will improve the noise levels substantially.

Then the two layers of Aerolite can be installed reducing the noise pollution and talking noise substantially.

Best Case Sound Proofing Wooden Floors at Building Stage

Fit Sondor rubber 10 to 15mm thick and 30mm wide to all beams. This application reduces floor contact noise.

Fit two layers 135mm Aerolite tightly between the floor beams. These beams are approximately 400mm apart.

This insulation must be cut wider than the beams and forced into the gap.

Installing the ceiling. This is the most important part of the application if you want the best sound proofing option. To get the best result we must remember we do not want sound transference.

We discussed this at the beginning. No part of the ceiling must come in touch with the floors above. Not even a single wire strand.

The idea is you want to fit your ceiling grid below the floor section above and the ceiling must not make contact in any way or form.

So ideally fit wooden beams below the floor beams and make sure that your builder does not nail or wire any part of the ceiling woodwork to the underfloor section.

This application will be the best as you will eliminate 90% of all walking noise as well as almost 100% of music and talking pollution as well.
