Junckers Winning Sports Floor Solutions are ideal for all types of athletic activities, from multi-use gymnasium and dance floors, to Olympic venues. Junckers is the recognized leader in solid hardwood sports floor systems all over the world. 2 EN 14904 The European standard for indoor sports floors The performance of a sports floor is measured according to the European standard EN 14904, which specifies the requirements on the properties of sports floors. The standard divides the sports floors into 4 types: 1. Area-elastic floors: When a point force causes deflection over a relatively large area around the impact point (wood). 2. Point-elastic floors: When a point force causes deflection only at or close to the impact point (vinyl). 3. Combi-elastic floors: An area-elastic floor with a point-elastic top layer, a point force will cause both localized deflection and deflection over a wider area (wood/vinyl). 4. Mixed-elastic floors: Point-elastic floor combined with a synthetic material. The standard relates to both safety and sports technical properties. The most important factors are described below. Key factors for safety and performance EN 14904 SHOCK ABSORPTION A shock absorbing floor minimizes the risk of injuries. Test results display the percentage of shock energy absorbed by the floor when 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. Test results display the floor’s vertical deformation in millimeters when exposed to a dynamic impact equivalent to that of light jogging. BALL BOUNCE A good ball bounce increases the ball control and the speed of the game. 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 athletes move rapidly on the floor. The ideal friction number is between 80 and 110. A friction number less than 80 makes the floor too slippery. A friction number above 110 makes the floor too sticky. ROLLING LOAD The floor’s ability to withstand rolling loads is important in 150 circumstances where heavy carts and retractable bleachers are KGS used. Test results display whether or not the floor can withstand a rolling load of 1,500 N (approximately 331 lbs or 150 kgs). 3 JUNCKERS SPORTS FLOORS – always area-elastic Junckers solid hardwood sports and dance floors are categorized as area-elastic, which is the flooring type that provides the best sport performance properties. An area-elastic sports floor allows optimal freedom of movement. It supports the game and protects the player against injury. A large quantity of all sports and dance injuries relate to poor performing flooring. EN 14904 sets demands for performance in two classes for area-elastic flooring. The standard performance class A3, and the higher performance class A4. Junckers offers solutions in both the “standard performance” class A3 and the “high performance” class A4. Floors in class A3 perform well for dance studios, group exercise, and multi-use gymnasium applications. Floors in class A4 provide the best in safety and performance, and exceed all performance standards set for the most elite sport and dance facilities. Junckers comprehensive testing In addition to the European standard testing, Junckers believes in testing a floor’s strength regarding durability and life span. Therefore Junckers has integrated two additional internal tests for results of these properties. Fatigue test This test is conducted on all Junckers “High Performance” class A4 sports and dance floors. The floor system is exposed to a series of controlled, dynamic point impacts of 3 kN (approximately 661 lbs or 300 kgs) no less than 100,000 times. This effectively simulates the equivalent of 25 years of normal use. Test of point loads The demands to the floor’s ability to withstand point loads are stepped up with the increased use of sports floors for exhibitions, trade shows, concerts and major sports events where retractable seating is moved across the floors. Here the demands of the EN standards are simply not sufficiently extensive. Therefore, Junckers sports floors undergo rigorous tests in order to ensure durable and versatile floors.

The product range of subfloor systems is extensive. Low profile systems allow for easy upgrades to existing facilities without a slab depression. Other systems are “shimmable” which allow for almost any finished floor height to be obtained, over most every type subfloor.
