INTRODUCTION

These guidelines concern Junckers sports floor systems installed over underfloor heating.

Please note that full documentation of a sports floor system with a built-in underfloor heating system comprises the data in E 4.0, E 4.4, see Fig. 1, and the data sheets of each sports floor system, see D 1.0. 


MOISTURE CONTENT IN WOODEN BASED MATERIALS

Battens and other wooden based materials included in substructures with underfloor heating systems should generally have lower moisture content than normally specified.

This because the wood will dry out more – in ideal conditions max. 10%. Engineered battens supplied with Junckers Sports Floor Systems with a moisture content of 8-10% are therefore particularly suitable.

Insulation up to the underside of the heat-distribution plates and heating pipes will reduce the heat loss.


COMPONENTS


1 - Boards
• Junckers 22 mm boards for sports floors

2 - Nails
• 22 x 45 mm machine J-Nails

3 - Batten systems
• Unobat 45, batten thickness 23 mm
• Blubat 52, batten thickness 30 mm

4 - Junckers Moisture barrier
• 0.20 mm PE membrane

5 - Subfloor
• Concrete with embedded heating pipes or cables

UNOBAT 45 AND BLUBAT 52 OVER UNDERFLOOR HEATING

Junckers Unobat 45 and Blubat 52 sports floor systems can be laid on concrete or screeded subfloors with cast-in heating pipes or cables. It is extremely important that the floor heating system is designed to achieve a stable temperature across the surface of the concrete or screed. The following applies to heating pipes in concrete or screeded floors:

To ensure an even temperature distribution, on casting there must be min. 30 mm of concrete or screed above the heating pipes. The pipes should not be spaced more than 300 mm apart, and the cables not more than 150 mm apart.

The residual moisture contained in the concrete or screed should not exceed 90% RH (UK: Concrete moisture max. 65% RH acc. to BS 8201, when checked by measurement).

Moisture barrier: All overlaps must be taped using 50 mm wide tape.

For detailed sports floor system information, see D 11.2 and D 6.2.

It is extremely important that the floor heating system is designed to achieve a stable temperature across the surface of the concrete or screed. The following applies to heating pipes in concrete or screeded floors:

To ensure an even temperature distribution, on casting there must be min. 30 mm of concrete or screed above the heating pipes. The pipes should not be spaced more than 300 mm apart, and the cables not more than 150 mm apart. The residual moisture contained in the concrete or screed should not exceed 90% RH (UK: Concrete moisture max. 65% RH acc. to BS 8201, when checked by measurement).

Moisture barrier: All overlaps must be taped using 50 mm wide tape. For detailed sports floor system information, see D 2.1.
