Sprung Subfloor, Shock Absorption Underlay

FlexiPro Series – Ballet, Sprung Dance Floor

FlexiPro Series is a high performance area elastic sprung floor, installed floating on levelled concrete or wooden sub-floors. Total height construction is 30mm for vinyl surface, or 35mm for timber surface.

The resilience of the floor system is secured through an elastic FlexiPro base floor, where continuous rubber strips in two thicknesses, placed in grooves on its back and feature progressive shock absorbency executed by low intensity impacts, from children for example.

The sports functional characteristics feature high shock absorbency and resilience combined with great stability under foot, ideal for multi-purpose use with a focus on dancing, active movement, and gymnastics, tested and conforms fully to EN 14904, Class A4.

A built-in deformation control secures ultimate loading capacity to the floor.
