Insulated sports halls

Energy-efficient halls for sports use

Weather conditions can be challenging for year-round practice of many sports. Janus halls can be used to cover even large areas without support columns. This makes it possible to practice many different sports at every time of the year. Moderate construction costs and energy efficiency ensure a cost-efficient alternative to traditional hall solutions.

The illustrative images include a football hall, an ice rink, a tennis hall, a padel hall, and a multi-purpose sports hall. For example, a four-court padel hall measures 25 metres in width and 52 metres in length.

Janus Oy has provided hall solutions for many different sports, such as tennis, ice hockey and golf. Get to know our sites and request a quote!
