As well as an appearance very close to that of natural slate, Swisspearl Westerland slates do not need to be graded and sorted like natural slate, enhancing its cost competitiveness with natural roof slate. 

 

Westerland slates are manufactured using Portland cement, superior blended synthetic and cellulose fibres and hard-wearing surface coatings. Westerland slates are pigmented during production and are fully compressed. Swisspearl fibre-cement slates are high-quality fibre cement products for new and refurbishment projects on residential, commercial or publicly owned buildings
