UnoBat 45

The UnoBat 45 System is a low profile, high performance sleeper based system. It is designed for use over flat subfloors.

The top solid hardwood is fastened to a resilient subfloor system consisting of 12’ long, ply-construction sleepers with pre-attached neoprene shock absorbing strips.

The shock absorbing strips are inset into a “U” shaped channel on the underside of the sleeper. This design creates a built-in stop block, ensuring the long-term resilience of the system.

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.
