The Harlequin Activity sprung dance floor is a permanently installed sprung floor system, based on the well-established ‘triple sandwich’ construction originated by Harlequin over 30 years ago. It’s a fully-floating system with no fixings to the sub-floor and can be laid on any reasonably smooth and flat surface without prior preparation.

Features and benefits:

Harlequin Activity is shock-damped to avoid a ‘trampoline’ effect and provides area and point elasticity to offer identical characteristics across the whole floor.
It is an ‘industry standard’ choice with many hundreds of installations worldwide, effectively reducing injuries to both teachers and performers.
Harlequin Activity is installed by highly-skilled technical team and all work is fully guaranteed.
Finished with solid wood in beech, oak, maple or bespoke.
Area elasticity providing 'give' or flexion over the section where a performer lands.
Point elasticity offering compression at the point of contact.

Tested in accordance with EN 14904-2006:

Shock absorption: 64%.
Vertical deformation: 3.8 mm.
Area deflection: 7.2%.
Rolling load: >1500 N.
Theatre Stage Concentrated Load: 3.6 kN/m² (367 kg/m²).
Theatre Stage Blanket Load: 5.0 kN/m² (509 kg/m²).

Installation:

A polymer damp-proof membrane is laid across the subfloor onto which is placed a layer of cellular polyurethane of proprietary density. Two layers of moisture-resistant semi-flexible panels are then installed and staggered, so that the joins do not coincide.
The top layer of panels is bonded to the one below with a non-setting adhesive and fastened mechanically.
The damp-proof membrane is folded onto the surface and secured to form a damp-proof seal. Then the solid wood top surface is installed and adhered. Finally, the gap between the flooring and the wall is filled with a matching wooden scotia fitted to the edge of the floor structure to form an attractive edge to the wall.

Components:

Top surface: Approximately 20 mm solid wood surface in oak, beech, maple.
Top panel: moisture resistant semi flexible board.
Cellular layer: cellular polyurethane.
Damp proof membrane: PE membrane.
Overall thickness: 52 mm including solid wood surface.
