Do you want to reduce sound transmission from your floor? Then it is important to first find out what type of subfloor you have. In this article, we will explain step by step how to effectively insulate a wooden subfloor against sound.
A wooden subfloor typically consists of a plank construction. It often contains gaps and openings that act as sound leaks. For good sound insulation, two types of materials are required:
By combining these materials, both airborne and impact noise are significantly reduced.
Step 1: Place soundproofing mass sheets
Lay solid sheets, such as EASYmass, directly onto the wooden subfloor. The thicker the sheet, the better the insulating effect. This layer seals sound leaks in the floor and adds mass.
Step 2: Add a vibration isolation layer
Apply a layer of vibration isolating material over the mass sheets, for example EASYbond. This absorbs the vibrations caused by direct (contact) sound, such as walking or sliding furniture, and indirect (airborne) sound like voices and music.
Step 3: Fit a edge strip against the wall
Place an edge strip of vibration isolating material along the edges of the floor, against the wall. This prevents the floor structure from making direct contact with the wall and reduces sound transmission via the walls.
Step 4: Install OSB or underlayment sheets
Lay OSB or underlayment sheets on top of the vibration isolating layer. Boards with a tongue-and-groove connection ensure a secure fit. In this case, one layer is sufficient. For even better sound insulation, and for heavily loaded floors, you can opt for a finishing with two layers of cladding. These sheets do not need to be tongued and grooved. Be sure to install the layers in a staggered pattern. Ensure that the sheets connect to the edge strip and do not lie directly against the wall.
Step 5: Finish the floor with a material of your choice
Choose, for example, laminate or PVC. It is also important that the finishing layer does not lie directly against the wall, but neatly connects to the edge strip.
For applications with stringent sound insulation demands, a professional installation system such as the EASYmount floor support offers the ideal solution. This system has been specifically developed to create a floating floor according to the mass-spring principle, ensuring the floor is fully acoustically decoupled from the substructure.
The EASYmount floor supports are placed in a grid, onto which wooden joists are mounted. Cavity insulation can be added between the joists for additional acoustic damping. The structure is then finished with a double top layer, resulting in a stable and highly sound-insulating floor system.
This solution requires greater technical expertise but provides a durable and scalable way to minimize both impact and airborne noise. It is ideal for residential buildings, commercial projects, technical rooms, or other projects with elevated acoustic requirements.
Discover the world of acoustics
A cavity is the hollow space between two parts of a construction, such as between two walls. This space often plays an important role in sound insulation and can be filled with suitable material, also known as cavity filling.
Would you like to improve the acoustics in your space and reduce sounds from above? Then enhancing the sound insulation of the ceiling is an effective solution. The right approach depends on the type of sound and the existing construction.
Do you want to make a wall soundproof? Sound insulation works well for airborne noise such as speech. If it concerns impact noise like vibrations from a washing machine, wall insulation is often not enough. In this article, you will learn how to effectively improve the sound insulation of a wall with the right system and material.
