Floating Floors

TVS Acoustics is a leading national supplier and installer of acoustic floors to commercial cinemas, theatres, gyms, residential and commercial buildings. TVS Acoustics work closely with architects, installers, engineers, construction companies and facility managers in order to provide the very best acoustics products. TVS Acoustics trades across the United Kingdom and internationally.

Both Impact and Airborne sound can be controlled using a variety of specialist noise reduction products. TVS offers a full range of resilient materials to reduce the impact sound transmission between floors, as well as full range of mass loaded systems to reduce the airborne sound transmission.

These solutions include under screed insulation materials, acoustic floating floors and acoustic underlay and underscreed materials. Our technical team can provide specification support and guidance over the suitability of different types of acoustic floor solutions for specific noise and vibration control applications.

TVS can also offer a range of assistance and suitable products if you are building to a Robust detail specification, looking for additional BREEAM credits, or wanting help achieving a Level 6 rating in the Code for Sustainable Homes assessment.

Description

TVS RESi FF Systems are designed to create a floating floor or slab to dramatically reduce impact and airborne sound transmission within building structures. The system can be used to support lightweight floors and screeds through to heavy raft foundations, with typical air gaps between floors ranging from 50mm to 150mm plus.

TVS RESi FF Systems will be designed by TVS engineers to meet key project specifications for natural frequency, load/deflection, air gap and ultimately acoustic performance.

The TVS RESi Floating Floor (FF) Systems utilises isolators produced from the high-performance range of Sylomer materials to support floated floor above. The low frequencies that these isolators can achieve dramatically reduce impact and airborne sound transmission within building structures. The system can be used to support lightweight floors and screeds, through to heavy raft foundations, with typical air gaps between floors ranging from 25mm to 200mm (although larger voids are easily achieved).

Through varying the Sylomer grade and isolator spacing, the RESi FF System can provide natural frequencies down to 5Hz, under a whole host of loading conditions. TVS RESi FF Systems will be designed by TVS engineers to meet key project specifications for natural frequency, load, deflection, air-gap and ultimately acoustic performance.

The Sylomer material is a high-performance polyurethane that offers a number of key advantages over other isolators:

- Low static to dynamic stiffness ratio (1.2-1.3 as opposed to typically 1.5-2.5 for rubber).
- Long service life (50+ years).
- Minimal creep.
- Excellent resistance to shock loads making these isolators ideal for gym environments.
- Ozone, temperature and chemically resistant to oils, grease, fuel etc.

  • Isolators can be custom made to meet project objectives

TVS RESi Concrete Systems

Concrete floating floors are the most common type of floated build-up as the additional mass that this system provides offers the greatest acoustic benefit. These systems also offer the greatest strength, whilst the large dead load that the floated slab provides ensures minimal movement under the addition of any live loading.

The TVS RESi FF System allows for a ‘pour in place’ construction, where the acoustic formwork is built and then the concrete is poured at the final design height with no requirement for any additional levelling or ‘jacking up’. This is very beneficial in terms of a projects programme and as such is often utilised in cinema auditoria where these floors are the last thing to be constructed before the shell is handed over to the fit-out contractors.


TVS RESi Dry Systems

It is not always possible to install concrete floating floors. The additional mass and point loading that a floated concrete slab can provide often makes it unsuitable, particularly within existing structures. Often there isn’t the floor height available to allow the addition of a concrete floated floor.

In these cases, layers of plywood, flooring grade chipboard and cement particleboard can be combined to provide a stable floated floor. The more mass that can be added to the floating floor the better the performance will be, however the build-up will often be limited by the available space and load capacity of the structure. These systems are often installed within pre-existing buildings with minimal disruption to adjacent areas.


Description

Floating floor and room-within-a-room structures represent state-of-the-art technology to control vibration and structure-borne noise within buildings. This technology is used to separate TV, broadcasting or recording studios, recital & rehearsal rooms as well as theatres, discos, fitness studios and HVAC areas dynamically and acoustically from the surrounding environment.

At system natural frequencies, ranging from 7Hz down to 2.5Hz, TVS Acoustics steel spring elements provide the most efficient solutions in protecting highly sensitive areas from mechanical vibration and structure-borne noise.

Mitigation of structure-borne noise and vibration starts at frequencies as low as 4Hz thus giving the TVS Acoustics system an advantage over elastic pad material.

Basic Spring Element System

TVS Acoustics offers a variety of spring element systems for floating floors. In addition to a large number of steel springs of different elasticity and load capacity there are several element systems available designed for a wide range of applications such as Embedded 'Jack-Up' Spring Elements or Supporting Spring Elements.

TVS Acoustics steel spring elements provide the most efficient solutions in protecting highly sensitive areas from mechanical vibration and structure-borne noise.
