Area v Point Elastic

Characteristics of Area Elastic Sports Systems v Point Elastic Floors

We are often asked why choose an area elastic sprung sports floor system rather than a point elastic foam-backed product. Below we illustrate the three types of available sports flooring options and briefly describe their characteristics with regards to shock absorption, comfort and vertical deformation – these are key elements for the protection of an athlete playing on a sports surface with an aim to reduce the risk of injury, enhance sports performance as well as provide a suitable surface for both sporting and non-sporting usage.

Area Elastic


Area elastic floors deflect an impact over a wide surface area. This provides high levels of shock absorption and comfort offering higher levels of performance and reduced fatigue to an athlete. The low rolling resistance is ideal for high performance sport and non-sporting usage.

Point Elastic


Point elastic foam-backed surfaces are prone to indentation and are easily damaged during non-sporting usage. We would not recommend point elastic surfaces for wheelchair sports.

Combined Elastic


Combined elastic floors are area elastic systems finished with a point elastic surface. However they are typically less cost-effective and often unsuitable for non-sporting events which most UK Sports Halls are used for.


Typical Construction of Area Elastic Sprung Systems & Point Elastic Floors

An area elastic sprung sports floor system can be constructed in two ways – the DYNAMIK Komfort Plus and DYNAMIK Flexi-Beam Plus systems can both be finished with a solid sport vinyl, solid sport linoleum, sport polyurethane or sport rubber playing surface.

Area Elastic – DYNAMIK Flexi-Beam Plus

 

The DYNAMIK Flexi-Beam Plus system can be packed and levelled to eliminate variations in the sub floor removing the need for a levelling screed. It is based on factory assembled elastic Flexi-Beams which support a counter floor and load distribution panel to accommodate a range of solid synthetic finishes. The structure of the system also allows underfloor heating and insulation to be incorporated between the beams if required.

Area Elastic – DYNAMIK Komfort Plus

The DYNAMIK Komfort Plus sprung system is designed to be installed on a level slab or screed and has a low construction height of only 22mm. It is an ultra low profile high performance sprung sports floor. The construction of the Komfort Plus system consists of a load distribution panel installed onto a comfort based elastic layer. It is ideal for overlaying existing sports floors and as with all area elastic sprung floors complies with the latest ESFA specification.

Point Elastic

Point elastic flooring comprises of a rubber crumb pad finished with a seamless polyurethane surface. This is typically a factory produced vinyl which combines a foam backing. This foam backing achieves low levels of shock absorption even though it feels soft, therefore is more suitable for facilities which do not require high sports performance such as pre-schools or spaces that do not intend to use heavy equipment, tables and chairs or incorporate non-sporting events such as exams.


Performance Characteristics of Sports Floor Systems

The table below confirms the performance characteristics that each type of sports floor must meet to comply with EN14904 which is the recognised standard for indoor sports flooring. A3 and A4 represent area elastic floors and P1, P2 and P3 point elastic floors.

SHOCK ABSORPTION (%)

Area Elastic (A) Combi Elastic (C) Point Elastic (P)
1 ≥25 <35
2 ≥35 <45
3 ≥40 <55 ≥45 <55 ≥45
4 ≥55 <75 ≥55 <75

VERTICAL DEFORMATION (mm)

Area Elastic (A) Combi Elastic (C) Point Elastic (P)
1 ≤2.0
2 ≤3.0
3 ≥1.8 <5.0 ≥1.8 <5.0 ≤3.5
4 ≥2.3 <5.0 ≥2.3 <5.0

With superior shock absorption and higher vertical deformation, A3 or A4 sprung sports systems not only offer high sports performance but also superior protection and comfort compared to any point elastic floor.

The DYNAMIK Komfort Plus and Flexi-Beam Plus systems can meet Class A3 or A4 performance criteria as required.


Principal Benefits of Sprung Area Elastic Systems v Point Elastic Surfaces

Multi-sport – Multi-use

Sprung systems finished in a solid playing surface, such as sport vinyl or sport linoleum, can be used in both sport and non-sport environments. This is important as a typical sports hall needs to combine sports usage as well as community use or social functions whereby the floor must cope with spillages, indentation caused by tables and chairs, stiletto heels or non-sporting footwear.

Surface Protection

It is essential if using a timber surface or point elastic floor that heavy duty protection such as DYNAMIK Giant Carpet Tiles be used to avoid indentation, tearing or puncturing of the surface. There is no requirement for protection with a sprung system finished with a solid synthetic playing surface.

High Loadings

Sprung area elastic systems can accept high loadings that arise when maintenance equipment or seating systems are used. The load distribution panels within the DYNAMIK Komfort Plus or Flexi-Beam Plus systems distribute and accept the high loadings perfectly.

Wheelchair Use

Point elastic foam-backed floors are generally not recommended or liked by wheelchair users as they provide a surface with a high rolling resistance and poor maneuverability which in turn can cause muscular strains and fatigue issues if the wheels sink into the foam backing. A3/A4 Sprung systems finished with a solid synthetic surface provide an ideal surface for wheelchair use with low rolling resistance and ideal maneuverability as well as high indentation resistance and durability.

25 Year Warranty

The DYNAMIK Komfort Plus or DYNAMIK Flexi-Beam Plus systems finished with a solid playing surface come with a 25 year warranty as opposed to 10 years typically offered for a P3 foam-backed surface.

Floating Floor

The DYNAMIK Komfort Plus and DYNAMIK Flexi-Beam Plus systems are “floating floors” and hence bridge any movement joints that maybe within the floor slab.

Low Life Cycle Costs

The DYNAMIK Komfort Plus and DYNAMIK Flexi-Beam Plus systems finished with a solid playing surface will have a life in excess of 35 years as opposed to 15 years for a typical point elastic floor.

Income Generation

If it is intended to let out your facility as an income generator then the amount of revenue received is directly linked to the performance of the floor. Clubs are becoming more selective as to where they play and have a wider choice. It is therefore worth ensuring you choose a high performance floor.


Pricing Considerations

When considering your new sports floor you may be surprised that the high quality DYNAMIK Komfort Plus or DYNAMIK Flexi-Beam Plus area elastic sprung sports systems compared to Point Elastic floors will give you a more cost effective alternative.

Specific pricing implications are due to the differences in construction methodology which are compared below:

Point Elastic

  • Requires a level slab
  • Usually requires a liquid DPM
  • May require a latex layer between the DPM and final surface
  • Underfloor heating has to be laid in the slab
  • Involves more wet construction processes
  • Requires a heavy duty protection system such as giant carpet tiles to protect the surface

Area Elastic

  • Can be built off the structural slab
  • Typically uses a visqueen DPM
  • A floating floor therefore not stuck down
  • Savings from less construction time
  • Underfloor heating can be installed between the beams
  • Depending on choice of surface e.g. sport vinyl or sport linoleum, no protection system is required

Once the above factors are considered a Point Elastic floor will typically cost more than a sprung area elastic sports floor system.

Feedback and Market Opinion

DYNAMIK regularly receive feedback from end-user clients, specifiers, architects and consultants who have stated that in their opinion a Sprung Area Elastic Sports System – finished in a solid synthetic playing surface – is much more suitable for use in educational facilities when compared to a point elastic surface or a sprung timber finish. It is clear that sprung systems finished in a solid surface provide high indentation resistance and low maintenance/life cycle costs – ideal for school usage.


Conclusion

For longevity, durability and cost effectiveness our DYNAMIK Komfort Plus system finished in a solid playing surface would be our recommendation if you require a Multi-Sport, Multi-Use floor and have a level slab or screed.

Alternatively, if you do not have a level slab or screed we would recommend our DYNAMIK Flexi-Beam Plus system.
