Floor soundproofing is one of the most effective methods for reducing noise in indoor environments. Whether it’s a home, office, or commercial building, minimizing unwanted sounds improves quality of life and productivity. In this article, we will explore seven top solutions for silent spaces, catering to different needs and budgets.
Below is a detailed analysis of each category, focusing on the scientific principles and practical applications of floor soundproofing:
1. Soundproofing Underlays (Under Screed)
Soundproofing underlays, including foam-based (Polymant, Microbit 4+2, SuperCanalee) and rubber-based options (Minigran, GreenSound), act as intermediate layers that absorb vibrations and impact noise (e.g., footsteps). The porous structure of these materials effectively reduces airborne noise by absorbing the energy of sound waves, offering high anti-vibration protection. High-density materials are particularly effective for heavy floors or high-traffic areas. Ensuring uniform installation is critical to avoid gaps or inconsistencies, which could compromise the anti-vibration performance.
2. Soundproofing Membranes Under Finished Floors (Direct Under Floor)
Direct under-floor soundproofing membranes are among the most efficient floor soundproofing solutions, especially designed for retrofitting existing constructions. They target a significant reduction in impact noise, such as footfall, and airborne noise.
This method involves the use of soundproofing materials like high-density membranes placed directly under the final flooring surface. These materials exhibit excellent acoustic properties while also providing durability against wear and moisture resistance. Due to their slim design, they are ideal for spaces where preserving available height is essential without sacrificing performance.
Direct under-floor solutions are perfect for residential or commercial renovations where installation speed and minimal structural alterations are crucial. For optimal results, proper installation by specialized teams is necessary to ensure complete coverage and avoid gaps or joints that diminish soundproofing efficiency.
3. Raised Acoustic Flooring
Raised floors, such as the FLS system, stand out for their exceptional acoustic properties, significantly reducing the propagation of structure-borne and impact noise due to innovative anti-vibration components integrated into the foot system. Additionally, the void created between the existing floor and the system can be filled with specialized sound-absorbing and soundproofing panels, further enhancing acoustic performance.
These features make it ideal for spaces requiring acoustic comfort and high anti-vibration protection, such as homes, offices, theaters, hotels, and studios. Furthermore, raised floors facilitate easy management of cables, pipes, and infrastructure, offering access for maintenance and upgrades. The robust construction ensures load resistance, while the modular structure adapts easily to space requirements. Raised flooring is a versatile solution combining functionality, durability, and acoustic performance.
4. Floor Soundproofing with Viscoren Floor Blocks in Lightweight Constructions (Wood or Cement Board)
Applying Floor Blocks under final surfaces like wood or cement boards is an optimal solution for vibration absorption and sound transmission reduction. This method is suitable for floors requiring acoustic comfort and easy installation, making it ideal for offices, homes, and medium-level soundproofing spaces. It is also recommended for studios where the appropriate weight of the final surface can effectively load the Viscoren Floor Blocks to achieve a low system resonance frequency.
Floor Blocks serve as an intermediate soundproofing layer, offering durability and stability with an emphasis on aesthetics and practicality.
5. Composite Floor Soundproofing Systems with Viscoren Floor Blocks Under Concrete Slabs
For demanding applications requiring superior soundproofing performance and anti-vibration protection, Floor Blocks are used as the base layer, followed by lost formwork and a concrete slab of appropriate thickness based on the desired loading level. This composite construction leverages the heavy mass of concrete to absorb low-frequency noise, while Floor Blocks provide exceptional vibration isolation.
This solution is ideal for industrial spaces, machinery rooms, and studios where durability and acoustic performance are critical. The system ensures long-term stability and effectiveness, even in high-stress environments.
6. Perimeter Isolation & Joint Soundproofing Coverage
The success of the above floor soundproofing applications requires careful consideration of perimeter isolation from existing structural elements. Materials like Superfascia AD (self-adhesive) or Polycell 22 AD (self-adhesive) ensure separation from sidewalls, making them entirely floating systems. Additionally, attention must be given to soundproofing membranes/underlays to ensure overlaps between joints using special adhesive tapes like Rotocell AD.
7. Combined Solutions
Combining different techniques (e.g., underlays with floating floors or membranes) provides comprehensive protection against all types of noise. These approaches are typically more effective for spaces requiring high acoustic performance.
Professional Installation of Certified Soundproofing Systems
For optimal results, professional installation of certified soundproofing systems is the best choice. It involves a combination of materials such as floating floors, soundproof panels, and other specialized products.
Advantages of Floor Soundproofing
Investing in soundproofing offers multiple benefits:
- Comfort: Reduces noise from footsteps, vibrations, and conversations.
- Increased Property Value: Soundproofed homes are more appealing to tenants and buyers.
- Health Protection: Noise reduction improves focus and reduces stress.
