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 irregular subfloors.

The top solid hardwood is fastened to a resilient subfloor system consisting of 2-layers of cross-laid engineered sleepers. The top sleeper has pre-attached pads that snap-lock into the lower sleeper’s J-locks. This ensures a fast, accurate and secure connection between the upper and lower sleepers.

The lower sleeper rests in our patented DuoWedge cradle, making it easy to correct even the most complicated subfloors into flat, ideal playing surfaces.

Support blocks are available in a variety of thicknesses to easily increase the height of the floor system as needed.

Solid hardwood flooring choices

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

The floors are extremely stable and therefore minimizes challenges when humidity levels change through the year. We take far longer than normal over the drying process to ensure 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 installed. This is because Junckers floors are sealed in the factory with our own produced hard wearing polyurethane.

All Junckers solid hardwood sports floors have the Danish Indoor Climate Certificate for low emissions of organic substances and can be delivered with either a FSC® or PEFC™ accreditation.

The installation process is always fast, easy and clean. Each prefinished plank is 12 foot long, and covers approximately 5 square feet.
