Floating Floor Foundation for Chiller, MEP & HVAC Isolation: How Farrat Floating Floor Systems Combat Noise and Vibration.
A Floating floor or Floating Foundation system is designed to create an insulated layer between the main concrete slab of a building and the base of the Chiller, MEP or HVAC equipment. The floating foundation comprises from several layers including rubber dampening Isolators and mats that will absorb vibration and prevent noise from entering the main structure of the building.

Our Floating Floor Foundation System will eliminate the floor slab vibration and minimize the airborne sound transmission that usually occurs from operating the electromechanical equipment such as, MEP, Chillers and HVAC systems.
Floating Floor Foundations have become increasingly critical, especially in urban environments where high-rise structures are the norm. With MEP (Mechanical, Electrical, and Plumbing) systems, HVAC units, and chiller installations commonly placed on rooftops, the challenge of preventing disruptive vibrations from penetrating through the main concrete slab is paramount. Farrat floating floor systems, also known as floating foundation systems, provide an effective solution for minimizing these issues. They are specifically engineered to address these challenges by creating a resilient barrier that separates vibrations from the main concrete slab. This innovative system comprises of several essential components designed to absorb and isolate vibrations effectively.

Common Application and Sources of Noise and Vibration:
As essential components of modern buildings, MEP and HVAC systems are notorious for generating noise and vibrations during operation. Chiller units can produce significant chiller vibrations that travel through structural elements, causing disturbances in lower floors. This can lead to discomfort for occupants and increased noise complaints, making it vital to implement effective control measures.
- Chiller Units: Generate low-frequency vibrations that can resonate throughout the building.
- HVAC Systems: Create both airborne noise and structural vibrations.
- Mechanical Equipment: Pumps and compressors contribute additional sound and vibration.
- Mechanical and Pump room Insulation: Pumps and compressors are insulated by providing a box-to-box system.

Installation Method of a Floating Floor Foundation:




Key Components of the Floating Floor Foundation:
- Underlay: This high-performance underlayment is designed to absorb vibrations and reduce sound transmission. Its rubber mat composition enhances its ability to dampen low-frequency vibrations from MEP equipment, ensuring a quieter environment.
- Isolators: These critical devices are strategically placed beneath mechanical units to decouple them from the building structure. Isolators play a vital role in minimizing vibration transfer, effectively absorbing shocks and vibrations before they can reach the concrete slab.
- Floating Floor: The design of the floating floor foundation allows it to “float” above the main slab, creating an effective barrier against vibration transmission. This design is especially beneficial in high-rise buildings where noise control is essential.
- Insulation Materials: The incorporation of rock wool, stone wool, or glass wool enhances the soundproofing capabilities of the system. These materials provide excellent thermal and acoustic insulation, further reducing noise transfer and improving overall building comfort.
Benefits of Implementing Farrat Floating Floor Systems
- Superior Vibration Isolation
The combination underlay, rubber mats, and isolators creates a robust system that effectively isolates MEP vibrations and chiller vibrations. This results in a significant reduction in the transmission of disruptive sounds and vibrations to lower floors.
- Enhanced Acoustic Comfort
With the installation of a floating floor foundation, occupants enjoy a quieter, more comfortable environment. The reduction in noise levels leads to improved concentration and overall satisfaction, particularly in residential and office settings.
- Compliance with Building Standards
Many building codes require specific noise and vibration control measures. Farrat floating floor systems help meet these standards, ensuring compliance while enhancing occupant comfort.
- Long-Term Cost Effectiveness
Although the initial investment in a floating floor system may be higher, the long-term savings from reduced soundproofing needs and improved tenant satisfaction make it a financially sound choice. Fewer complaints and a more pleasant environment lead to lower turnover and maintenance costs.
Real-World Applications
Chiller units can produce significant operational vibrations that travel through structural elements, causing disturbances in lower floors. This can lead to discomfort for occupants and increased noise complaints, making it vital to implement effective control measures.
Farrat floating floor systems have been successfully deployed in various building types, from luxury residential buildings to commercial spaces. In one notable instance, a high-rise mixed-use development implemented a floating foundation to manage rooftop HVAC units. As a result, tenants reported a significant decrease in noise complaints, attributing their comfort to the innovative design of the system.
Conclusion
As urban living continues to evolve, effective noise and vibration control is crucial for enhancing the quality of indoor environments. Farrat floating floor systems offer a practical and efficient solution to prevent the transfer of MEP and chiller vibrations through the main concrete slab. By integrating components like GenieMat FF underlay, rubber mats, isolators, and high-quality insulation materials such as rock wool, stone wool, and glass wool, these systems significantly improve acoustic comfort and building performance.
For architects, developers, and building owners looking to create quieter, more comfortable spaces, investing in Farrat floating floor systems is a strategic choice. To learn more about how these systems can benefit your building project, reach out to a specialist today!
Neoprene Isolators
Neoprene isolators are devices made from neoprene, a synthetic rubber, designed to absorb and reduce vibrations, noise, and shock in various mechanical or structural systems. They are commonly used in applications where controlling vibration and ensuring structural integrity are critical, such as in HVAC systems, machinery, and building foundations.
Key Features of Neoprene Isolators:
- Durability: Neoprene is resistant to wear, weather, oils, and chemicals, making it suitable for long-term use.
- Elasticity: It provides excellent cushioning and vibration damping due to its flexible nature.
- Wide Temperature Range: Neoprene can function effectively across a broad temperature spectrum, typically from -20°C to 120°C (-4°F to 248°F).
- Noise Reduction: It helps minimize noise transmission through machinery or building structures.
Types of Neoprene Isolators:
- Pads: Flat neoprene sheets used under equipment to dampen vibrations.
- Bushings: Cylindrical isolators used in automotive or industrial machinery to absorb shock.
- Mounts: Often combined with metal components, these isolators support equipment while dampening vibration and noise.
- Seismic Isolators: Used in buildings to reduce the impact of ground vibrations during earthquakes.
Applications:
- HVAC Systems: Placed under compressors, fans, or ductwork to prevent vibrations from propagating through the building.
- Machinery: Protects sensitive equipment from external vibrations and reduces noise transmission.
- Automotive: Used in suspension systems to absorb shocks and enhance ride comfort.
- Construction: Isolates structural components to prevent vibration transfer between floors or sections of a building.
