This anchored resilient system utilizes factory assembled panels with natural rubber pads and allows air circulation throughout the subfloor structure while supporting heavy loads. The Aero HL (High Load) also allows complete movement as a system when the floor expands or contracts. This floor system is highly resilient, has uniform playability and consistent shock absorption to enhance safety for athletes. Action’s Aero HL Floor System is an excellent choice for gymnasiums, multipurpose, indoor running, dance floors and aerobic projects.
