ALL-WOOD ENERGY RESPONSE SYSTEM
CAD* | WORD | PDF | WARRANTY | ENVIRONMENT

The All Wood ERS and ERS R1 are DIN compliant, state of the art resilient sport flooring systems that maximize the comfort, safety and performance characteristics today's athletes demand from beginners to the most advanced professionals.

The All Wood ERS System exceeds the recommendations of the Otto Graf Institute's DIN 18032, Part II Safety and Performance Standard. ERS floors exhibit a higher Impact Force Reduction Factor (shock absorption) than required by the standard and meet the minimum deformation (deflection) requirements at point of impact. The ERS System offers a high level of returned energy to the athlete combined with the system's shock absorption properties, this helps reduce injuries and fatigue.

The ERS R1 System includes extra restraint in the form of metal clips, which help stabilize the entire floor system. Both systems are manufactured from materials with proven longevity and wide use in the construction industry, which keeps costs low and helps make the ERS systems the most economical of their type available today.
