TECHNICAL ANALYSIS

TVS RESi floating floor systems

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.

  • Suitable for concrete and timber floating floors

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 Floating Floor 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.
