The Tau Rotunda planter is made from fibreglass, a composite material of glass fibre and synthetic resin that is lightweight while offering a high degree of strength. The structure of the planter is finished in concrete, providing a robust appearance and durability. The product is suitable for both outdoor and indoor use, making it highly versatile. Thanks to its frost resistance, the planter can remain outdoors during cold periods without risk of damage. The UV resistance offers protection from ultraviolet radiation, preventing discolouration and damage caused by sunlight.
