UV stability testing on WIENERBERGER roof tiles

Wienerberger is one of the largest producers of high quality, durable façade bricks, wall clay blocks, roof tiles, pipe systems and pavements.

Increasing durability, sustainability and circular economy are primary goals for Wienerberger. In order to improve and check quality of their products and new developments, Sirris was contacted to perform long term UV stability testing on varnished clay roof tiles. Colour stability and water repellency are important properties which are evaluated during the testing period.
