Soundproofing Wooden Floors in Existing Homes

This application is a little more complicated than installing it at the building stage. Sound transference is the biggest problem with floors already in place with a ceiling below. Sound transference is carried 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 in 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, we must either lift the floor or remove the ceiling. It will add cost to the application. Ideally, we must tightly fit two 135mm Aerolite Insulation layers between the beams. There must be no airspace gaps between the top and bottom.

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

Application Was Floor Boards Have Been Removed

This is the ideal scenario rather than removing the ceiling, as this application reduces walking noise. In this application, all the Floor beams will need a 10 to 15mm Sondor rubber fitted along the beams’ length.

The advantage of fitting the Sondor rubber is reducing the impact of walking noise. However, this will not eradicate noise but substantially improve noise levels.

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

Best Case Soundproofing 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 of 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 is the most important application if you want the best soundproofing option. We must remember that we do not want sound transference to get the best result.

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.

Ideally, fit wooden beams below the floor and ensure 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 and almost 100% of music and talking pollution.

Stop Sound In Adjacent Rooms

To stop sound in adjacent rooms, we will also have to insulate the roof space to prevent noise from entering the home via the roof space.

Soundproof A Room

To Soundproof a Room, we need to insulate the floor and the roof space. Because Noise Pollution moves, we must track the noise to solve the noise pollution issues.
