Life4 quality for life
Life4 - Looking better for longer
Benefits
Marley rainwater systems perform well. However, time takes its toll on everything and inevitably, gutters fade and lose their shine over the years.
Life4 makes this a thing of the past
Extensive research and development into material technologies has been carried out, the results include five years of performance data. This is based on natural weathering tests on similar capping materials used across the World in New Zealand, South of France and North Australia.
The benchmark for weathering tests for rainwater systems is set out within European standards*. The weathering test essentially mimics actual conditions, but also accelerates them in order that long term performance may be assessed. This artificial ageing type test consists of 1600 hours of exposure to high intensity UV lighting with specified levels of irradiation and condensation, which is designed to emulate approximately 3 years of natural weathering.

Life4 has been tested to three times the length of the standard BS607:2004 accelerated weathering test. Life4 satisfied the pass criteria.
In order to demonstrate the enhanced performance of Life4, products were exacted to three times the standard test duration or 4800 hours. Measurements taken after the extended test showed that the extent of colour fade was still well below that permitted in the European Standard after 1600 hours. The results can be seen below.
