The Great Barrier Leaf is guaranteed for five years from date of purchase against premature UV breakdown (embrittlement) of the High Density Polyethylene (H.D.P.E.) provided the product is maintained in accordance with the manufactures instructions.
The guarantee will not cover any colour fading in that period.

Experience in the Plastics Industry indicates that black (H.D.P.E.) has a life expectancy of around 15 years subject to climatic and pollution conditions.

The Great Barrier Leaf System uses the natural elements of wind and rain to clear away excess leaves.
