Westerland slate has an appearance very close to that of natural slate. Its attractive riven surface and natural dressed edges make it an ideal solution for situations where a traditional appearance is important. Like all fibre cement slates Cembrit Westerland is lightweight, pre-holed and easy to cut with hand tools meaning nuisance dust is eliminated. Furthermore, as with other fibre cement slates Cembrit Westerland does 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. Cembrit fibercement slates are high quality fibercement products for new and refurbishment projects on residential, commercial or publicly owned buildings.
Please note that these product properties are not a replacement for the manufacturer's literature and it is always recommended that Cembrit is consulted before specifying.
