DuoBat 120+

The DuoBat 120+ System provides the ultimate in high performance and safety, along with virtually unlimited leveling flexibility to accommodate all types of uneven subfloors. The 22 mm solid hardwood floor boards are fastened to a subfloor system consisting of 2-layers of cross-laid engineered battens.

The top batten has pre-attached resilient rubber pads that snap-lock into the lower batten’s J-locks. This ensures a fast, accurate and secure connection between the upper and lower battens. The lower batten rests in an adjustable and locking DuoWedge cradle, making it easy to correct even the most complicated subfloors into flat, ideal playing surfaces. Levelling the floor is conducted without use of nails and tools.

Packing blocks fitting the adjustable DuoWedge cradle are available in a variety of thicknesses to easily increase the height of the floor system as needed.

Choice of floorboard

A Junckers sports floor is made from 100% solid hardwood and will last for generations. Each floor board is made from two rows of staves and is tongue and groove jointed all round.

The floors are extremely stable and therefore cause no challenges when humidity levels change through the year. We take far longer than normal over the drying process to ensure that the movements that occur naturally in all wood is fully controlled and kept to a minimum. Our Beech and Maple sports floors are dried using Junckers unique press drying method.

Our floors are ready to use as soon as they are fitted. This is because Junckers floors are sealed in the factory with our own produced hard wearing polyurethane lacquer.

All Junckers solid hardwood sports floors can be delivered with either a FSC or PEFC accreditation. The floors are A plus rated in the BRE Green Guide and have the Danish Indoor Climate Certificate for low emissions of organic substances. A Junckers sports floor gives you the best floor for your health and the environment.

We guarantee fast and easy installation. Each floor board has a length of 3700mm and covers approx. 0.5 m².
