The performance of any sports floor is dependent upon both the construction of the sub structure and the flooring itself and as well as the interaction between the two. Solid hardwood is the choice of athletes because it provides area rather than point elasticity. All Junckers sports floors are of 22mm solid hardwood with timbers especially chosen for their tensile strength, straight grain structure and optimum area elasticity, ensuring the maximum freedom of movement. A choice of timber grades and sub-structures ensures the optimum flooring for everything from dance and general purpose sports floors to squash courts, and all at a choice of performance levels - all are designed to enable athletes to train longer and play harder without fear of injury (more information on sub-structures can be found on the right). Furthermore, a Junckers sports floor provides a healthy indoor climate - they are certified to Danish Indoor Climate Certification rules and are the only solid hardwood floors to conform to the British Allergy Foundation specifications.
PERFORMANCE TESTING
In order to meet EN14904 Junckers sports floors must undergo the following performance tests:
SHOCK ABSORPTION
A shock-absorbing flooring minimises the risk of injuries. Test results display the percentage of shock energy absorbed by the floor when, for example, landing after a jump.
VERTICAL DEFORMATION
The floor’s ability to absorb shock depends on its ability to flex when exposed to a dynamic load. The test results display the floor’s vertical deformation in millimetres when exposed to a dynamic impact equivalent to that of light jogging.
BALL BOUNCE
Correct ball-bounce increases the ball control and the speed of the game. The test results display the rebound achieved by the floor as a percentage of the rebound measured on a concrete floor.
FRICTION
Correct friction is important when, for example, ball-players move rapidly on the floor, and the ideal friction number is between 80 and 110. A friction number less than 80 makes the floor too smooth; a friction number above 110 makes the floor too rough.
POINT LOAD
The floor’s ability to withstand point loads is important in circumstances where carts and the like will be utilised. The test results display whether or not the floor can withstand a point load of 1.500 N (approximately 150kg).
In addition to these tests Junckers have introduced further tests for strength and durability:
FATIGUE
Conducted on all high performance floors the floor is exposed to a series of controlled, dynamic point impacts of 3kN (approximately 300kg) a minimum of 100,000 times, simulating the equivalent of 25 years of normal use.
HIGH STRENGTH
Given the increasingly diverse useage many sports floors are subject to - exhibitions, fairs, concerts and major sporting events - when retractable seating is moved across the floor, Junckers consider the rolling load requirements of the EN testing to be insufficient and have introduced their own, far more rigorous strength tests.
