SPECIFIER INFORMATION

GENERAL DESCRIPTION OF FLOOR SYSTEM

Junckers Portable Flooring System is based on 22 mm solid boards, prefabricated into panels/elements and laid floating on resilient foam underlay. The floor system is an area elastic type of sports floor with medium shock absorbency and elasticity suitable for fitness and aerobics as well as a temporarily sports floor, e.g. with special line markings for a given sports game.

The construction height is 27 mm or 32 mm, depending on the thickness of the foam underlay.

The floor system when 10 mm foam is used will conform to EN 14904:A3.

Please note that full documentation of a floor system comprises the data in D 1.0, D 1.1, 3.1 and D 3.1.1, see Fig. 1.

SYSTEM SPECIFICATIONS

The Portable A3 Sports Floor System is installed as a floating floor on a dry, load-bearing floor of concrete, lightweight concrete or wooden materials, e.g. an existing sports floor.

The subfloor must be flat with a maximum deviation of 2 mm under a 1.5 m straight edge (UK: 3 mm under a 2 m straight edge). The surface must be smooth. Any minor irregularities must be corrected. The choice of intermediate layer depends on the structure of the subfloor and the moisture conditions. 

FLOOR ELEMENTS

The elements are laid in an interlocking pattern so that all joints are staggered 900 mm from row to row. The elements are locked together with pre mounted assembling fittings. Lengthwise the elements have a tongue and groove connection and at ends the elements are joined using loose tongues.

NB: Centre Row elements are available on request with this system. Centre Row elements comes with assembly frames on each side of the elements, and are laid out in the middle/centre of the floor as a starting row

SPACING TO WALLS AND FIXED INSTALLATIONS

2 mm per metre of floor width on each side, min. 30 mm. Is also required at fixed points, e.g. columns.

RESILIENT MAT

The choice of resilient mat depends on the properties of the subfloor. If the subfloor is fully or partly inelastic Junckers 10 mm Sports Foam is used, while for elastic subfloors, e.g. existing sports floors with certain resilient properties, Junckers 5 mm Sports Foam. 

ACCESSORIES

Transport trolley: Designed to load 40 pcs. of 1/1 elements
Perimeter trims: Metal ramp as finish of the floor
Removal hook: For removal of loose tongues when dismantling the elements
Loose tongues: Supplied in plastic

MOISTURE BARRIER

On ground floors and where there is a risk of moisture penetration a moisture barrier of 0.20 mm PE membrane, e.g. Junckers Moisture Barrier, is laid directly on the concrete.
