Our panels are embedded with UV inhibitors so there is no specific material deterioration due sun exposure. Additionally, rain or snow will not affect the integrity of the panels; just squeegee or shovel off before using and you’re ready to skate! In hotter climates, a shelter over the rink could be considered to shade athletes from the direct sun...or in regions where there are deciduous trees, the shelter could help limit the debris clean up. As a rule of thumb, an outdoor surface should be covered with a tarp when not in use.
