Soundproofing for Wooden Floors

Soundproofing structural wooden floor

Soundproofing structural wooden Floor
Due to a lack of weight (mass), wooden structural floors allow lots of sound and vibrations to travel through. You can almost literally follow conversations and footsteps sound like dull thumps. A good starting point for soundproofing is therefore by adding mass in the shape of Isomat KE Fiber. Two types of Isomat KE J are available, aa variant of 8 Kg/m² and of 14 Kg/m². Use the heaviest type for the optimal result. The heavier the floor, the better the soundproofing. You can compare Isomat with a subfloor sheet of 1 by 1 meter and about 6 mm thick.

How to soundproof a structural wooden floor
In short, make the wooden construction floor dust-free and seal all seams and cracks. Equip the Isomat KE14 with a layer of Stauf Extreme Tack on the side that contains fiber inlay and put the Isomat plates tightly against the walls and against each other. Gluing is not necessary if the floor is smooth and does not creak.

Now that you have the Isomat in place, you can choose to immediately add a floor covering or, even better yet, a plywood finishing board of at least 12 mm. This covering can be screwed upon the Isomat and gives the floor more rigidity. Due to the additional weight (more than 14 kg per m²) the soundproofing value increases considerably and the nuisance decreases.

Adding weight to the construction is generally not a problem. If you have any doubt about this, consult your contractor or the architect of the building/home. You will find the extensive step-by-step plan for insulating wooden floors on our tips page.
